gypsum as an additive to cement smokys-pizza.fr

Sodium silie cement uses either sodium silie (2Na 2 O·SiO 2, water glass) or sodium metasilie (Na 2 O·SiO 2) as an additive to Portland cement. Sodium silie is a liquid additive, while sodium metasilie is a soluble granular solid. The action of both additives during solidifiion is similar. gypsum,cement additive

What is the purpose of adding gypsum in cement?

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”. If not added, the cement will set immediately after mixing

Gypsum: An additive for stabilization of swelling clay

However the use of gypsum as a stabilizing agent is currently not clear. This paper deals with the performance of the gypsum as an additive for treatment of the expansive clay soils by means of swell potential and strength. Optimum water content for the best compaction of the bentonite was first determined by standard compaction tests.
