Strength and Durability Characteristics of CementSand
May 05, 2020 Varying proportions of cement, coarse sand (CS), and fine sand (FS) were used in a quest to find an optimum combination for producing CSEB that meet the design criteria outlined in several standards. Inclusion of 50%60% CS is found to provide maximum density and compressive strength, and beyond 60% CS content, strength begins to drop.
