Abstract
Abstract To address questions concerning the behavior and performance of white cement concrete, a research program was designed to conduct comparative studies of type I gray and white portland cements. Different properties of cement paste and cement mortar, made with the two different cements, were measured and compared. Test results indicated shorter setting time of white cement paste and greater ultimate tensile and compressive strength for its mortars than the corresponding values for the gray cement. Results of tests on samples of fresh concrete indicated greater slump and shorter times of initial and final set of mixes prepared with the white cement. Tests conducted on samples of hardened concrete indicated greater ultimate compressive strength of the white cement cylinders. Finally, full-scale companion reinforced concrete beams, identical except for the type of cement, were designed to fail in shear or in flexure. Test results indicated no difference that could be attributed to the type of cement used. Advanced Cement Based Materials 1995, 2, 161–167
