  • Specific Gravity of CementDetails Test Procedure

     · The specific gravity of cement ranging from 3.1 to 3.16 g/cc. By this statement we can ensure that cement 3.1-3.16 times heavier than water of the same volume. And it sinks in water. Because the specific gravity is greater than 1. Every material consists off so many little pores which may contain voids in it.
