Product Description

We are in the position to supply and export Alumina Cement CA40, CA-50, CA-50N, CA-50G9, CA-50Fused, CA-60, CA-70, CA-80.

CA70 is as pure calcium alumiante cement, which get by calcining industrial grade aluminium oxide and fine limestone under high tempeature in rotary kilns and grinding in ball mills. It suits for top grade high temperature resistant low cement and as excelelnt hydraulic binder usded in refractory materials for high temperatre equipment of metallurgy, chemistry and powder station.

Application:
Adding into refractory castable as furnace lining
For anti-sulfate corrosion project
For projects requiring quick hardening and emergency repairing
For special projects constructed in winter
As raw material of calcium aluminate powder in water purifying agent
As adhesive for ceramic tile etc
A better choice for making expansion cement, self-stressing cement and other special cement
Welcome to contact for detail specification and discuss together.
