Cement is a hydraulic bonding agent which is obtained by heating, then grinding, a mixture of limestone and clay. Most cements are made from clinker and additives and are usually used in the form of a powder. Cement sets when mixed with water. Combined with sand and aggregates (sand or gravel), it turns into rock-hard concrete or mortar.
Sep 22, 2020 In some specific process conditions (e.g. Vertical Roller Mills), the use of conventional high performance strength enhancers can lead to process limitations. These sides effects are often controlled by reducing the dosing rate of cement additive. However, this leads to a lack of grinding aid in cement to achieve all the benefits from the chemicals.
