High alumina self-flowing castable
Introduction
High alumina self-flowing castable also named vibration free castable. Its raw material is first class calcined bauxite, corundum fine powder, a-Al2O3 fine powder, SiO2 fine powder, CA-70, CA-80 and so on.
After adding water or other liquid into high alumina castable material and blender it, then high alumina castable degassing, flowing evenly and smoothly its-self based on gravity, and this process is good to densification.
Features
High alumina self flowing castable has the performance low cement and ultra low cement cadtable, and according to its rheology feature, high alumina self-flowing can reduce actual construction time, no noise, low labor strength and high working efficiency.
