Specific Gravity of Cement - Detailed Explanation – Civilology

If the specific gravity of cement is greater than 3.19 then, the cement is either not minced finely as per the industry standard or it has more moisture content which will affect the mix and bonding. This is why you find lots of chunks while mixing old stock cement for concrete.
