A natural mineral, gypsum is known as hydrous calcium sulfate or selenite and is aggressively mined in Iowa, Oklahoma, Texas, Nevada and California. A popular product for the construction industry, gypsum is used in wallboard (sheetrock). As an ingredient, it can be found in chalk, plaster of Paris and Portland cement.
The effects of the additives are reduced or enhanced by modifying the additive or by using additional additives. For most downhole requirements, more than one additive is needed. This give-and-take relationship between additives is the basis of cement-slurry design. Effects of additives
Forton® VF-774 is the world-wide standard concrete additive for making lightweight GFRC panels. It is recognized by the PCI as the only polymer supported with a 20 year durability study. Alpha gypsum additives make gypsum far stronger and more weather resistant. Forton® and Matrix products are a lower cost alternative to resins.
This method of mix proportioning is especially popular when producing high-strength concrete and fiber-reinforced concrete. Adding 1-2% plasticizer per unit weight of cement is usually sufficient. Adding an excessive amount of plasticizer will result in excessive segregation of concrete and is not advisable. Depending on the particular chemical ...
PLASTiFLO acts as a cement and colour dispersion agent in the render wet mix as well as a water reducer. The work effort necessary applying the wet render to brickwork is far less than conventional cement sand mixes. It is quite noticeable there is less strain on the elbows and shoulder joints.

Cementitious plasters that contain Portland cement have been traditionally lightened by the use of inorganic lightweight aggregates, such as vermiculite and perlite. Gypsum plasters have been lightened by using chemical additives to create bubbles that displace solids, thus reducing the bulk density.
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 .
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 cement".
