| Abstract: | Evaluation of effects of C3A and SO3 contents in Portland cement on its compressive strength, hydration rate and products. Three cement samples varying in C3A content and one varying in SO3 content were used, hydrated initially at three temperatures. Compressive strength, bound water content, free lime content and Differential Scanning Calorimeter curves were determined during the progression of hydration. In interpretation bound water was used as a measure of quantity of binding material and Free Lime to Bound Water Ratio (FLWR) - of chemical constitution and quality. |
