The dependence of the compressive strength upon dry density, water content, curing conditions, cement type and, most importantly, foaming agents employed in the cement paste is here investigated
2020-7-31Mainly Specific Gravity is the is the ratio of the density of a substance to the density of a reference substance at a fixed temperature. On the other words, it is the ratio of the mass of a substance to the mass of a reference substance. And the theme is also same for cement. Specific Gravity of cement is the ratio of the density or mass of cement to the density or mass of a reference
