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.

Aksüt, Yavuz Selim; Yetgin, Sukru
In this study; the engineering properties of volcanic rocks obtained from four different quarries in the province of Erzincan region in the Upper Euphrates Part in the Eastern Anatolia Region were investigated. In laboratory studies, the experiments including bulk and aggregate tests (bulk and dense unit weight, specific mass, water absorption, Los Angeles test for resistance to wear, freezing resistance and uniaxial compressive strength) were conducted on 5 volcanic samples according to the standards (Turkish Standard, British Standard and ASTM) and in the second stage, grading of concrete tests (grading of the concrete aggregates, concrete preparation, slump test, specific density of concrete, uniaxial compressive strength, modulus of elasticity, splitting tensile strength, abrasion resistance and capillarity) were performed on the concrete samples with volcanic aggregates. For fresh concrete composition, water/cement ratio was selected as the main variable providing homogeneous mixing and the highest strength to the concrete samples with a specific granulometry. Cylindrical concrete samples were produced with a variety of water/cement ratios cured for 7 and 28 days in water and their compressive strengths were assessed in the light of their physical and mechanical properties. The results obtained from aggregates and concrete tests, which were performed in line with the standards showed that especially Yassitepe-Dogu (YTD) sample, one of the volcanic rocks from Erzincan region can be used as concrete aggregate. It was observed that compressive strength of the concrete samples could satisfy C25/30 strength class and upper classes. In addition, it was understood that they can be used in highways, bridges, dams, buildings etc., especially as structural concrete.
