Abstract
In this study the resistivity effect of laboratory-produced S2Cl2 as an additive in Portland cement PC 32.5 which was hydrated at the water/cement ratio of 0.5 and room temperature against sulfate attack in the curing solution of 0.35M sodium sulfate was investigated. Hydrated cement products were determined by using X Ray Diffraction (XRD) and Thermogravimetry—Differential Thermal Analyses (TG-DTA) techniques. The additive substance, S2Cl2 in Portland cement, was used 5 and 10 percent by weight. The highest compressive strength value was found as 36.7 MPa in case of hydrated cement PC 32.5, samples containing 5% S2Cl2 (additive) after curing time of 28%21 days.
