Floor Leveling with Gypsum Concrete. Gypsum Concrete continues to be one of the most versatile and cost effective floor levelers that we offer. It can be installed from 1/4"-4" thick in a single lift, it dries faster than concrete, it finishes flatter than concrete and it costs less than cement based self leveling products.
The terms cement and concrete are used interchangeably, although cement is actually an ingredient of concrete. Gypsum is often added to cement and concrete to slow down the drying time. Cement dries quickly and retarding that process allows workers to pour the mixture into the various forms or frames needed.
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of ...
Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needle-like gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
