(Gazi Univ, 2017) Tekin, Ilker; Kotan, Turkay; Yurdakul, Muhammet; Oner, Erdal
In this study, the limestone, natural aggregate, serpentine and Bayburt stone located in the province of Bayburt used as aggregate in conventional concrete production. In the experiments, the cement dosage and workability were kept constant. Slump, Ve-Be, unit weight and the highest temperature values in first 2 hours of the fresh concrete were measured. The concrete samples prepared with Bayburt stone were cured for 90 days and the others were cured for 28 days in lime-saturated water. Strain-stress data and water absorption values were measured on the hardened concretes at 7 and 28th days age through the records of stress and strain data during compressive strength tests. According to results of this study, the compressive strengths of the concrete samples with limestone, natural aggregate and serpentine were on average of 40, 35 and 5 MPa, respectively, on the 28th day. Also, in concrete samples with Bayburt stone, the compressive strengths were reached to 16 MPa for 28 days and to 22 MPa for 90 days.
