High alumina self flowing castable

The main difference between self-flowing castable lies in that it significantly increases the proportion of fine powder in raw materials. After adding water, it has excellent fluidity and can automatically fill those hard-to-reach corners.

Other name: High alumina self-leveling castable

Model Number: SF50, SF55, SF60, SF65

Certification: ISO9001-14001

Minimum Order Quantity: 5 MT

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.
