MoreJan 11, 2021 The specific gravity defines that the substance is how much heavier than water or reference substance of the same volume. This specific gravity of cement ranging from 3.1 to 3.16 g/cc.By this statement, we may ensure that cement 3.1-3.16 times heavier than this water of this same volume, and it sinks in water.. Because the specific gravity isn’t less than 1, every material consists

MoreSpecific Gravity of cement is the ratio of the density or mass of cement to the density or mass of a reference substance. But in both of the state's density or mass, the volume should be same. If the volume does not remain same the specific gravity has no existence then.
