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.
CA50-N is super-early-strength aluminate cement, which produced by well selected buxite and superior limestone through strict components contrl, perfect temperature control in rotary kilns and fine milling. Its high strength can be obtained within 6hours, especially for refractory.
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.
