high alumina refractory cement

high alumina refractory cement 1).make high performance refractory castable and chemical construction.

high alumina refractory Cement Fused HXCA-50

   high alumina refractory Cement Fused CA-50,is produced by melting selected high quality bauxite and fine limestone in electric furnace,cooling,and then being ground in ball mill.CA50 Fused has the characteristic of high and early strength and high flowability so that it is suitable to formulate refractory castable of high performance and be used in chemical structure.

1.Features:

1).The main phase CA content approx.70-80%.2).Has long initial setting time and long work time.3).The interval of initial setting time and final setting time is short,it is availed to improve the strength and to remove the mould.4).The Good flowability could improve the word performance of concrete effectively. 5).Impurity content is lower,The strength of middle temperature down extentlesser.6).A perfect bond for formulating rapid hardening high strength and good flowability refractory castable.7).The bond for formulating gunning material with resistance to abrasion and mechanical skock and resistance to elevated temperature.8).Formulating for self-flowing groud materials9).Formulating for rapid hardening mortar,ceramic tile paste agent,stop water project materials.
