More importantly results of flexural strength tests indi e a substantial improvement in flexural strength for gypsum composition 2 that includes an enzyme after 7 days and after 28 days as compared to gypsum
How Much Weight Can a Sheetrock Ceiling Hold? eHow The compressive strength -- resistance to pressure bearing on it -- of traditional 1/2-inch gypsum board is 400 pounds per square inch psi but the boards aren& 39;t rated for live and dead loads. Attaching weight in the form of fixtures directly to the ceiling Sheetrock would add pressure in a localized area -- rather than distributing the weight or transferring the load throughout the material.

Gypsum block - Wikipedia Gypsum blocks are composed of gypsum plaster water and in some cases additives like vegetable or wood fiber for greater strength. Partition walls made from gypsum blocks require no sub-structure for erection and gypsum adhesive is used as bonding agent not standard mortar. Because of this fundamental difference gypsum blocks shouldn& 39;t be confused with the thinner
