Product Description

Outline Aluminate cement is produced by preparing raw meal consisting of applicable bauxite and limestone, calcining the raw meal in rotary klin and grinding the clinker, which contains Al2O*****9%。It was called bauxite cement for a time and also called "refractory cement"based on its main ***** name"aluminate cement"is specified by the national standard now. Character & uses The main minerals in aluminate are monocalcium aluminate (CA), monocalcium dialuminate(CA2), "*2:7"calcium aluminate(C*2A7), gehlenite(C2AS), minor perovskite(CT) and dicalcium ferrite(C2F).Among these minerals, CA hydrates rapidly and sets normally with characters of rapid hardening and early strengthening;CA2 hydrates slowly and contributes to late ***** compressive strength at 3d for the cement reaches about *0% of the maximum strength, thus in the national standard, the compressive and flexural strengths at 1d, 3d are specified to determine cement grades. The aluminate cement can resist a high temperature at which a relative high strength still ***** refractoriness increases with the content of ***** it is suitable to make refractory concrete as a binder.Depending on the refractory aggregates(firecaly, high alumina)used, the refractory concrete made of the cement can be used below ***0OC. If it is used in construction, attentions given in the appendix GB**1 must be followed. Products quality Aluminate Cement manufactured by sintered method in rotary kiln are according with up-to-date standard GB*******0, which are graded as G6, ***** new products super-early-strength type CA**-N and high-strength type CA**-G9 are to be introduced in addition, whose quality standard are based on CA*0 OF GB*******0.
