An investigation was carried out on white cements for its different strength properties such as setting times and strength for different proportions of aggregates and curing periods. Similar test were performed on gray cement to compare the results. Three different colour of mosaic stones such as white, black and gray were used as coarse aggregate in this investigation. White and gray portland cement was collected from the local market. In this purpose fineness of white cement was determined using 200 No. Sieve and the initial and final setting time of both the cement were determined. Concrete cylinders of size 3"x6" were fabricated for three different proportions 1:1, 1:1.5 and 1:2. Mortar cubes of size 2.78" and Briquette at different proportion were also made. Compressive strength of cylinders was tested for 7, 14, and 28 days of curing periods. Compressive strength and tensile strength of mortar cubes and Briquette were also determined at 3 days of curing period. The test results revealed that maximum strength of cylinders was obtained for proportions 1:1 and strengths increased with curing period. It was also found that strength properties of white cement are almost two-third to that of the ordinary portland cement.
