CSA cement clinker
CSA cement clinker is a pure cement clinker,also called csa binder in field of china constructin building materials. In fact, it is a hydraulic binder based on Calcium sulphoalumniate,rather than portland cement which consist of calcium silicate or alumina cement which consist of calcium aluminate. Its main efficient content is ettrigite.It can be gained after reaction with each other and the volumn is twice than the mixture of limestone,bauxite,gypsum ect. Due to 85% of ettringite is formation in early period, it has good durability and short stable time. It also can be used as concrete additive agent like high early strength agent, anti-crack waterproofing agent, anti-freeze agent, rapid hardening agent ect. Besides,it has good adaption to other cement, chemical auxiliary agent, mineral materials ect.
