Influence of sulphate soil on concrete behaviour belonging Siirt and Batman region

In this thesis, the ratio of sulphate was determined from the samples of sulphate soil which was taken from Siirt and Batman site field. The performance of mineral additives concrete was obtained both in the sulphate and water cures. In this context, three series of concrete samples was produced; in two concrete samples series the certain ratio of fly ash and granulated blast furnace slag was used as additives, and one series of sample was used without additives. The cube samples were rested individually in water cure and (15%) sodium sulphate solutions at room temperature. The compressive strength and surface hardness of samples, which were exposed to effect of sulphate, was measured at the certain time intervals. Furthermore, the weight difference and surface deformation of these samples was also observed periodically. Consequently, in this thesis the used soil was taken from Siirt-Batman region, the observation was primarily focused on how the sulphate soil effects on the compressive strength of concrete was researched, and it showed that sulphate decreased the strength of concrete.
