Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "C-S-H," the dashes indicating ...
Water vapor leaves the surface of a concrete slab at a rate that is called the Moisture Vapor Emission Rate (MVER). When you read in a sealer data sheet that the MVER needs to be 3 pounds or 5 pounds, what that means is the number of pounds of water vapor per 1000 square feet per 24 hours.

The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added. The basic components of the cement production process.
Batch dry grinding tests of cement clinker were performed in a ball mill measuring the power input investigating the effects of operating conditions and material environment on the specific energy. Gypsum and pozzolanic tuff used as grinding additional compounds improve energy efficiency by decreasing the specific energy for a given Blaine fineness. For a fineness of 3500 cm 2 /g, the optimal ...
