Aksüt, Yavuz Selim; Çullu, Mustafa; Yetgin, Sukru
The indirect assessment of concrete compressive strength using non-destructive techniques, including the Schmidt rebound hammer and ultrasonic pulse velocity methods, is crucial for evaluating and tracking the strength of structural concrete used in construction and rehabilitation projects. However, studies focusing on alkali-activated concrete (AAC) remain insufficient. This study investigates the mechanical properties of fiber-reinforced alkali-activated concretes (FAACs) produced with short curing times, addressing this gap in the literature. Ground blast furnace slag (GBFS) was used as the binder, and waste volcanic rock dust (RD), produced in a natural stone processing plant, served as a fine filler. These materials were activated with sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) to produce alkali-activated concrete, both without fibers (AAC) and with fibers (FAAC). Steel fiber (SF) and polyester fiber (PYF) were used separately and in hybrid forms at 0.25%; 0.50%; 0.75%, and 1.0% volume fractions, resulting in a total of 117 cubic specimens (15x15x15 cm). The specimens' mechanical properties were evaluated using regression analyses based on data from Schmidt rebound number (RN), ultrasonic pulse velocity (UPV) non-destructive methods and uniaxial compressive strength (UCS) destructive tests. Optimized functions predicting compressive strength based on RN and UPV measurements were developed, highlighting the significant effects of fiber type, ratio, and mode of use. Additionally, multivariate prediction models were statistically developed using data from the three test methods.

Aksüt, Yavuz Selim; Çullu, Mustafa; Yetgin, Şükrü
Alkali Activation Concretes (AAC) have many superior properties compared to Ordinary Portland Cement Concrete (OPC). However, it shows traditional concrete behavior with its brittleness. In this case, the tensile strength and flexural strength which are weak in addition to ductility is being studied to be increased by using various artificial and natural fibers. In this context, it is inevitable to conduct multifaceted research to improve the behavior of Fiber Alkali Activated Concrete (FAAC). In this study, 13 different mixes were made using steel and polyester fibers in different proportions by volume (0%; 0.25%; 0.50%; 0.75%; 1%) separately and hybrid. The mechanical properties of cubic (150 × 150 × 150 mm), cylindirical (100 × 200 mm) and prismatic (150 × 150 × 600 mm) specimens were determined including compressive strength, modulus of elasticity and poison ratio, splitting tensile strength and flexural strength (toughness-energy absorption capacity and modulus of rupture). crack formation in concrete occurs early and a significant decrease in strength is observed due to the high flexibility and low flow resistance of polyester fibers. Steel fibers with high strength and higher yield strength were used in hybrid form to solve this problem. It was revealed that the blend ratio that contributed the most to the mechanical behavior of the specimens was the case where the fibers were used as hybrid at a ratio of 1% by volume evaluation from both the experimental results and the optimization.

Aksüt, Yavuz Selim; Çullu, Mustafa; Yetgin, Şükrü
In this study, ground granulated blast furnace slag (GGBFS) and quarry rock dust (RD), both industrial and natural mineral wastes were used as binder materials in geopolymer concrete. The influence of these mineral admixtures on the concrete’s durability under aggressive environmental conditions was investigated. Steel, polyester, and hybrid fibers were incorporated at volume fractions of 0%, 0.25%, 0.50%, 0.75%, and 1.0% to further enhance durability performance. Freeze-thaw and sulfate resistance tests were carried out to evaluate the effects of fiber type and content on the durability behavior of the geopolymer concrete. The test results showed that the mineral waste-based binder system itself offered considerable durability while the addition of fibers significantly improved resistance to freeze-thaw cycles and sulfate attacks. Among all types, the geopolymer concrete with 0.5% polyester fiber exhibited the highest resistance to freeze-thaw while hybrid fiber usage provided a balanced enhancement across both test environments.

The objective of the study is to determine the effects of different fibre types and ratios on the mechanical and physical properties of alkali-activated concrete (AAC) and to optimise important properties such as workability, unit weight, water absorption, compressive strength, modulus of elasticity and abrasion resistance of these concretes. Concrete samples were produced using steel and polyester fibres at ratios of 0.25%, 0.50%, 0.75% and 1%. The fibre ratios were varied, and various tests were conducted to determine the mechanical and physical properties of the concrete samples. The experiments clearly revealed the effects of fibre types and ratios on the performance of concrete. These results clearly demonstrate the effects of different fibre types and ratios on the mechanical and physical properties of AACs. Particularly noteworthy is the water-retaining property of polyester fibres, their effect on workability and their enhancing effect on abrasion resistance. The effects of steel fibres on compressive strength and modulus of elasticity are more pronounced, but they may present disadvantages in terms of workability and abrasion resistance. It is observed that mixed fibre usage provides a good balance in some properties. This study provides a roadmap for evaluating sustainable material options in the concrete industry and guiding future research.

Eker, Hasan; Demir Şahin, Demet; Çullu, Mustafa
This study aimed to determine the effect of fly ash added to concrete with high calcium content (C class) and different fineness on durability properties such as the alkali–silica reaction (ASR). By substituting ultra-fine fly ash for cement at specific proportions in concrete mixes and increasing the fly ash fineness, fly ash filled the spaces between cement grains or aggregates in concrete and accelerated the hydration process. Thus, the mechanism of ASR development was reduced. Class C Afşin Elbistan ash was used and was ground in a ball mill for 0, 10, 20, 30, and 45 min, and Blaine fineness values of 1555, 1632, 2347, 2589, and 2766 cm2/g were obtained, respectively. For each fly ash fineness, the effect of mixtures with 10%, 30%, and 50% replacement of cement on the ASR mechanism was observed during curing periods of 3, 7, 14, and 28 days compared to concrete without fly ash admixture. Furthermore, the effect of the increased fineness and substitution rate of fly ash with high calcium content in cement on the microstructure was revealed by microscopic mineralogical images. The prepared fine fly ash added to concrete mixes at different replacement ratios showed ASR reducing properties compared to the concrete mix without additions. The fly ash fineness and the substitution rate in the concrete had a reducing effect on the ASR, and this effect resulted in values lower than the reference concrete value.

Beton bileşiminden biri olan çimentonun hidratasyonu ile sülfat iyonları arasında oluşan kimyasal reaksiyon sonucu sülfat korozyonu oluşmakta ve bu oluşum betonda bozulmalara neden olmaktadır. Sülfatın beton üzerinde oluşturduğu hasarı azaltmak ya da en aza indirmek için çimento yerine uçucu kül gibi puzolanlar kullanılmaktadır. Bu çalışmada betonun ana bileşenlerinden biri olan çimento yerine çimentoya yakın bileşene sahip olan Afşin Elbistan Termik Santralinden temin edilmiş uçucu kül atığı kullanılmıştır. Uçucu külün (UK) bilyalı değirmende 0, 10 ve 20 dk öğütülmesi ile elde edilen farklı inceliklere sahip örnekler % 10 UK ikame oranı ile hazırlanarak uçucu kül katkılı beton örnekleri oluşturulmuştur. Daha sonra bu örnekler; % 5 ve % 10 katkılı sülfat çözeltisine maruz bırakılmış ve beton örneklerinin sülfat direnci üzerine etkisini araştırmak için basınç dayanımı ve ultrasonik dalga hızı ölçümü testlerine tabi tutulmuş, ağırlık kayıpları incelenmiştir. Elde edilen sonuçlara göre uçucu kül öğütme süresine bağlı olarak % 5 ve % 10 sülfat çözeltisine maruz bırakılmıştır ve daha sonra katkılı beton örneklerindeki basınç dayanım değerlerinde artışlar gözlenmiştir. Sülfat çözeltisi miktarının artmasıyla birlikte beton örneklerinin basınç dayanımının azaldığı ve bu beton örneklerinin referans örneğine göre daha yüksek basınç dayanımı değerine sahip olduğu görülmüştür. Bununla birlikte; öğütme süresinin artmasıyla ağırlık kayıplarının azaldığı görülmüştür. Ayrıca; öğütmenin etkisi ile uçucu külün inceliğinin artması sonucu ultrasonik dalga hızı değerlerinin de arttığı belirlenmiştir.

Külekçi, Gokhan; Çullu, Mustafa
Various studies on the disposal or storage of the wastes generated due to mining activities have been carried out until today. With the developing technology, the use of alternative products instead of aggregates in Composite and the effect of fiber addition were investigated. The most common of these studies is the bending strength tests on the beam sample. In this study, solid wastes generated by mining operations were used instead of aggregate used in Composite. Beam samples were poured with the dimensions of 40x40x160 mm by adding 4-6 kg/m(3) polypropylene fiber to the mixture obtained by using these solid wastes; then, its effects on ultrasonic pulse velocity test, tensile test, and compressive strength tests were conducted. According to the results of these tests, it was found that the fibers had a positive effect on compressive strength and bending strength. Also, it was found that water absorption rates and densities did not have an effect, while the ultrasonic pulse velocity decreased with increasing fiber content.

Demir Şahin, Demet; Çullu, Mustafa; Eker, Hasan
Too much CO2 is released during cement production. In many researches, the use ofnatural or recycled compounds plays an important role in the cement composition.The use of these components contributes both to reducing the amount of waste andto protecting the environment in nature. It is possible to produce an environmentallyfriendly concrete, thanks to its being a fly ash thermal power plant waste and its useas mineral additive in terms of its composition. In this study, it is aimed to produceimpermeable concretes with the use of C type fly ash as substitutes for cement in concrete composition in substitution rates of 10 %, 30 % and 50 %. In order to reduce thepermeability of concrete in this direction, as a result of grinding the fly ash in the ballmill for 0, 10, 20, 30, 45 and 60 minutes, concrete samples were prepared with andwithout admixture (Reference). Capillarity test was performed to determine the permeability at the end of cure periods of 28 and 90 days on concrete samples. Accordingto the results obtained at the end of 28 days, the best impermeability was achieved inthe mixture with 50 % fly ash replacement and 60 minutes grinding time. In 90 days,the best impermeability was obtained in the mixture with 30 % fly ash replacementand 0 minutes of grinding time. As a result, it was seen that permeability decreasedwith increasing thinness and substitution rate of fly ash in concrete composition.

Bu çalışmada Afşin Elbistan/ Kahramanmaraş termik santral atığı C tipi uçucu kül (UK) kullanılmıştır. Bu kül öğütülmüş ve 6 farklıincelik değeri elde edilmiştir. Uçucu küle ait değişik incelik değerleri ile betonda çimento yerine % 10, % 30 ve % 50 ikame oranlarındakullanılarak katkılı ve uçucu kül katkısız referans beton örnekleri hazırlanmıştır. Sertleşmiş beton örnekleri üzerine uçucu kül incelikdeğerinin etkisini belirlemek için aşınma ve karbonatlaşma direnci deneyleri yapılmıştır. Aşınma direnci ASTM C 944-99 standardındaifade edilen Rotating Cutter yöntemine göre 28, 56 ve 90 günlük kür süresini tamamlamış beton örnekleri üzerine uygulanmıştır.Karbonatlaşma direnci için örnekler 360 gün karbondioksit miktarı yoğun bir ortama bırakılmış ve karbonatlaşma derinliğibelirlenmiştir. Elde edilen deney sonuçlarına göre; % 10 ve % 50 uçucu kül ikameli beton numunelerinde öğütme süresinin yarmadaçekme dayanımı üzerinde pek fazla etkili olmamış, ama referans numuneye göre uçucu kül ikamesinin dayanımı artırdığı anlaşılmıştır.Ayrıca % 30 uçucu kül ikameli beton numunelerinde öğütme süresinin yarmada çekme dayanımını çok az artırdığı görülmektedir, ancakbu karışım oranıda referans numunenin elde ettiği dayanım değerinin altında değer almıştır. Beton karışımlarına ikame edilen uçucu küloranlarının artmasıyla birlikte karbonatlaşma derinliği artmıştır. En yüksek karbonatlaşma derinliği değeri 0, 20, 30 ve 45 dakika öğütmesürelerine sahip % 50 UK ikameli beton örneğinde (1,0 cm), en düşük karbonatlaşma derinliği değeri (0.3 cm) ise 10 ve 45 dakikaöğütme süresine sahip % 10 UK ikameli beton örneklerinde elde edilmiştir. Elde edilen sonuçlara göre; beton karışımlarında kullanılanUK’ün öğütme süresinin karbonatlaşma derinliği üzerinde pek fazla değişikliğe neden olmadığı görülmüştür. % 10, 30 ve 50 UK ikamelibeton karışımları içerisinde en fazla aşınma miktarı 28 günlük kür süresinde meydana gelmiştir. % 10 UK ikameli beton karışımındaöğütme süresi artıkça 28 günlük kür süresi numunelerinin aşınma miktarınında genel olarak arttırdığı söylenebilir, ama 56 ve 90 günlükkür sürelerinde pek etkisi olduğu söylenemez. Diğer UK ikame oranlarında (% 30 ve 50) öğütme süresinin artmasıyla 28, 56 ve 90günlük kür süresine sahip numunelerinin aşınma miktarlarında belirgin bir değişiklik gözlemlenmemiştir.

Çullu, Mustafa
The purpose of this study is to investigate the physical and mechanical properties of concrete produced from lead-zinc mine waste (tallow) products. In this context, the physical chemical, mineralogical and petrography characteristics of rocks obtained from zinc-lead mine were analyzed first. Concrete strength classes of C16/20, C25/30 and C35/45 5 replaced with 25%, 50% and 75% rates of limestone were prepared with lead mine waste. The physical and mechanical properties of the prepared concrete samples were determined. As a result, when lead-zinc mine waste is used as concrete aggregate, while the porosity and the water absorption of prepared samples were decreased, the physical density were increased as compared to limestone. As the result of the positive effect of physical properties, compressive and tensile strength were increased.

The objective of this study is to observe the radiation shielding efficiency of concrete produced by using the lead wastes that are stored in lead-zinc mines processing of which is not financially viable in the mines they are extracted from that have negative effects on the environment. Within this scope, concretes were produced to be used as radiation shield concretes. The samples were prepared by altering the amounts of heavy aggregates such as lead–zinc mine waste, Magnetite, Limonite, and Barite at 25%, 50%, and 75% ratios, and concrete samples were prepared in C16/20, C25/30, and C35/45 concrete strength grades to determine the effects of these grades on radiation absorption properties. In order to determine the radiation absorption coefficients, absorption coefficients at 662 keV, 1173 keV, 1332 keV, and 1460 keV energy levels from Cs-137, Co-60 and K-40 sources were determined by concrete slabs with dimensions of 20 × 20 × 5 cm.

Çullu, Mustafa; Ertaş, Haydar
The aim of this study is to determine the radiation absorption capacity of concretes produced from lead mine waste which cannot be processed economically as the lead content is low in the mines they are extracted. Lead mine waste (tallow) were exchanged at ratios of 25%, 50% and 75% respectively with barite and limestone aggregates and samples were prepared at C16, C25 and C35 classes. The compressive strength and the unit weight of the prepared samples were determined. The linear absorption coefficients of prepared concrete samples at 662 keV of energy were determined. In addition the relationship between the radiation absorption capacity and the compressive strength–unit weight was investigated. The experiments demonstrated that best absorption was in concrete samples with 100% barite content (100B). On the other hand in the concrete samples prepared from the mixture of limestone and lead mine waste aggregates, it was observed that radiation absorption capacity decreased due to decreasing amount of barite. In concrete samples prepared from the mixture of lead mine waste and limestone aggregates, it was observed that radiation absorption capacity increased due to increasing amount of mine waste aggregates in the concrete. As a result it was observed that lead mine waste aggregates do not absorb as much radiation as barite aggregates depending on the ratio increase of lead mine waste in the aggregate added to the concrete mixture. However the absorbed radiation amount was observed to be higher compared to limestone aggregates.

Mineralogical and chemical properties, as well as the pozzolanic activities, of the volcanic rocks in the northeast of the Black Sea were examined. Physical and mechanical tests were conducted on samples collected from the study area and the feasibility of using volcanic rocks as pozzolanic admixture in the concrete industry was investigated. Mortar samples containing admixture in the ratios of 0%, 10%, 20%, 30%, 40%, and 50% were prepared by keeping fineness of pozzolanic admixtures fixed. By using these mortar samples, prismatic mortar samples of 4×4×16 cm were prepared and the samples were cured in water. Their 7-, 28-, and 90-day tensile strengths, compressive strengths, and ultrasonic pulse velocity were determined. As a result, it was determined that volcanic rocks can be used to produce blended cement by considering their specific gravity, pozzolanic activities, and compressive strengths. It was noted that increase in trass rate significantly reduced tensile and compressive strength of cement in the early stage as expected.

Bolat, Hakan; Şimşek, Osman; Çullu, Mustafa; Durmuş, Gökhan; Can, Ömer
Attempts to find a construction material having increased strength, ductility, toughness, and durability have led to interest in high performance fiber reinforced concrete. The use of such materials increases day by day. When the fibers are distributed in a homogeneous way and used in appropriate quantity inside the concrete, they reduce cracks, contribute to tensile strength, toughness, ductility and durability, and improve other mechanical properties. In this study, four types of concrete were produced: steel fiber (SFRC), polyester fiber (PYFRC), polypropylene fiber (PPFRC) reinforced concrete and a reference sample made of plain concrete (R1); these were then compared to one another. The ratio of fibers was used 4.25% of volume of concrete. The effects of the different types of fiber on hardened concrete were determined by conducting physical and mechanical experiments. Compressive strength, surface hardness, ultrasonic pulse velocity, carbonation, abrasion, capillarity and freeze-thaw resistance experiments were conducted on hardened concretes. SFRC had higher 12.4%, PYFRC 3.4% higher and PPFRC 4.3% lower compressive strength with respect to R1. PPFRC showed 8.04% higher compressive strength than R1 when it was determined by the surface hardness method. SFRC showed 5.4% higher compressive strength than R1 when we applied the ultrasonic pulse velocity method. In the abrasion experiment, the highest abrasion was found in SFRC with ∼0.5%, while the lowest was found in PPFRC at ∼0.18%. The highest and lowest amount of capillary water absorption was seen in R1 and PYFRC, respectively. In a carbonation experiment, SFRC was determined ∼130.8% higher than R1. It was concluded that the types of fiber used for reinforcement influenced the physical and mechanical properties of the concrete.

This study investigates the effects of corrosive conditions on the physical and mechanical properties of concrete produced in cold weather. 30% calcium nitrate and 5% hydroxyethylaminemixture (HEA) were used as additives in antifreeze. Within 15 min of placing the prepared concrete samples in molds, the samples were put in a deep freezer. They were exposed to frost at 0 C, -5 C, -10 C, -15 C and -20 C degrees in the deep freezer over two days. The samples were taken out of the freezer and removed from the forms one day later. They were cured in water at room temperature until the 28th day. The samples were then exposed to sulfuric acid of 5% concentration (H2SO4), magnesium sulfate of 7500 mg/L concentration (MgSO4), sodium sulfate of 5% concentration (NaCl), and corrosive cure and water-curing until the 120th day. At the end of the curing period, the permeable pore space volume, water absorption ratio, unit volume weight, capillarity ratio, impermeability, compressive strength, static modulus of elasticity, Poisson's ratio and tensile strength values of the concrete samples were determined. The results showed that the physical and mechanical properties of the concrete were negatively affected by the corrosive conditions.

This study examined the effects of antifreeze on the physical and mechanical properties of the concrete which are produced in cold weather. 30% Calcium Nitrate and 5% hydroxyethylaminemixture (HEA), Calcium Nitrate (KN) and Polyhydroxy Amine (PA) were used as additives in antifreeze. Prepared concrete samples were placed in a formwork and exposed to the frost at 0 °C, -5°C, -10°C, -15°C and -20°C for 2 days. Afterwards, concrete samples in the freezer were cured at the room temperature until the 28th day and permeable pore space volume, water absorption ratio, density, capillarity ratio, impermeability, compressive strength, static modulus of elasticity, Poisson's ratio and tensile strength values of the concrete samples were determined after the curing. In conclusion, 30% Calcium Nitrate and 5% hydroxyethylaminemixture (HEA) were found to be giving the best performance among the antifreeze types. The physical and mechanical properties of the concrete were negatively affected from all antifreeze types due to the temperature decrease of the exposed fresh concrete.

Arslan, Metin; Çullu, Mustafa; Durmuş, Gökhan
This study aims to determine the effect of antifreeze admixture used in the concretes subjected to frost action on the concrete compressive strength. Three groups of concrete samples of C30 class were prepared with antifreeze admixtures by using the mixture of 30% calcium nitrate and 5% hydroxy ethoxy amin (A), calcium nitrate (B), Polyhydroxy amine (C). Concrete samples are put in the freezer in a fresh state 15 min after the mixing. Samples are subjected to frost action in 0, -5, -10, -15 and -20°C degrees for 48 hours. On the concrete samples water cured after 48 hours, compressive strength tests of 28 day are conducted. Consequently, it is seen that with the increase of the set temperature that concrete is cured, compressive strength of concrete is decreased and among all types of antifreezes the maximum decrease is seen between 0 and -5°C while the decrease in compressive strength is relatively less for -10, -15 and -20°C.
