Ordinary portland cement and portland cement composite What is the difference?

Cement generally divided into ordinary portland cement, mixed with Portland cement and special cement mix materials. Portland cement: a mix of proportional ground limestone, clay, iron ore, a mixture of raw material at this time is called. Followed by calcination, generally at a temperature of about 1450 degrees, calcined product called clinker. Then clinker and gypsum together ground, according to the mixing ratio, it is called cement. Blending materials Portland cement is Portland cement in proportion to the machining program and certain other substances added to achieve special effects, such as slag cement, pozzolana cement, fly ash cement, composite Portland cement and so on. The cement raw materials than the original ordinary portland cement to be more active or inactive mixed material mixed material. Special cement is somewhat different phases in materials and production process, such as alumina cement (aluminate cement) materials are bauxite, calcined limestone get clinker, then ground to become aluminate cement. There are some other minor characteristics of cement use, such as white cement, mainly for decoration, the material is pure kaolin, pure quartz sand, pure limestone, at the right temperature calcination mature material.
