The density of a material is defined as its weight per unit volume for blasting. Explosive densities are expressed in grams per cubic centimeter (g/cc). Blasters can relate to these metric units because water density is 1 g/cc. Therefore, explosives with densities higher than 1 g/cc will sink in clear water.

Gypsum Board - an overview ScienceDirect Topics

Gypsum boards or plasterboards are typical materials used to build light walls. The production process is based on gypsum hydration technology. At the very beginning of the process dehydrated calcium sulfate (gypsum) is converted into CaSO 4 0.5H 2 O by heating. Once dehydrated, gypsum is mixed with water, starch, a foaming agent, and other additives.
