Measure the increase in volume caused by the dry solids displacing some of the water. Assume the new volume is 550 c.c. The displacement, then, is 50 c.c. (550-500). Divide the weight of the dry solids (200 gr.) by the difference in volume (50 c.c.). The result, 4.00, is the specific gravity of the dry solids.

Specific gravity in natural stone ranges from 2 to 3, meaning that stone is two to three times denser than water. Water Absorption and Bulk Specific Gravity in Stone Specific gravity doesn’t exist in a vacuum, however; when it comes to the performance of natural stone products, other physical properties must be accounted for.
