Questions & Answers Concrete FAQ’s. A small amount of gypsum is added during the grinding process to control the cement's set or rate of hardening. days after placement for conventional concrete-the concrete surface needs to be kept moist to permit the hydration process. new concrete can be wet with soaking hoses, sprinklers or
Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into arocklike mass. This hardening process continues for years meaning that concrete getsstronger as it gets older.
(A) The degree of grinding of cement, is called fineness (B) The process of changing cement paste into hard mass, is known as setting of cement (C) The phenomenon by virtue of which cement does not allow transmission of sound, is known as soundness of cement (D) The heat generated during chemical reaction of cement with water, is known as heat
May 12, 2020· Grinding is the next step in the cement manufacturing process, and it can occur in either wet or dry forms. Wet grinding involves combining all of the materials in a mill with water and grinding it into slurry. In contrast, dry grinding processes combine and grind the materials without water, creating a substance known as kiln feed.
