Cement Accelerator is an admixture for the use in concrete Concrete is a construction material composed of cement as well as other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate such as gravel, limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures. The word concrete comes from the Latin word "concretus" (, Mortar (masonry) Mortar is a workable paste used to bind construction blocks together and fill the gaps between them. The blocks may be stone, brick, cinder blocks, etc. Mortar becomes hard when it sets, resulting in a rigid aggregate structure. Modern mortars are typically made from a mixture of sand, a binder such as cement or lime, and water. Mortar can also be, rendering or screeds. The addition of Cement Accelerator speeds the cure time and so allows concrete to be placed in winter without the worry of frost damage. Typical materials used for acceleration are CaCl2, and NaCl.
