Product Decription | Portland cement, binding material in the form of a finely ground powder, usually gray, that is manufactured by burning and
grinding a mixture of limestone and clay or limestone and shale. The inventor Joseph Aspdin, of England, patented the basic
process in 1824, naming it for the resemblance of the cement when set to portland stone, a limestone from the Isle of Portland.
When mixed with water, the anhydrous calcium silicates and other constituents in the portland cement react chemically with the
water, combining with it (hydration) and decomposing in it (hydrolysis) and hardening and developing strength. Portland cement is
the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most
non-specialty grout. It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the
clinker, and adding small amounts of other materials. Several types of Portland cement are available with the most common being
called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available. |
