CA50 series of calcium aluminate refractory binder consist of CA50-G5,CA50-G6,CA50-G7,CA50-G8, CA50-G9,CA50-N and CA50-fused.
CA50 series of Calcium Aluminate refractory binder are made of bauxite and limestone or calcined limestone which are sintered with proper ratio at high temperature in the rotary kiln , (or fused in arc furnace ). The clinker will be pulverized to form calcium aluminate binder whose main mineralogy phases are CA and CA2. With low content of Fe2O3(2.5%).
Character :
1. Quick hardening and early strengthening
2. Used in urgent repairing
3. Used in the project under construction in winter
4. Sound anti-corrasion from sulfate effect
5. Anti-freezing
6. High purity
