high aluminate refractory cement

super-early-strength high alumina cement 1).quick hydrating and hardening 2). high strength in short time.

high alumina cement CA-50-N

  CA50-N is super-early-strength high alumina cement, which is developed by our company in 1992 as a new cement in our state. It is produced by well selected bauxite and superior limestone through strict components control, perfect temperature control in rotary kilns and fine milling. Its high strength can be obtained within 6 hours .Its capability and quality is similar to Lafarge's products. It is a new type of aluminate cement, which is specially suitable for refractory purpose and can completely replace imported products.

1.Features:

1).the setting time is normal.Its quick hydrating and hardening property makes high strength in short time.Its strength can reach 30Mpa in 6 hours after hydrating.2).It is an ideal binder for rapid-hardening and high-strength low cement castables.3).It is also suitable for high alumina or fireclay low-cement refractory castables used under 1450°C.4).Its price is much lower than pure calcium aluminate so that it can makes the cost lower.5).It needs moisture proof protection and an be used at least within six months if it is stored under dry conditions.
