Product Description

Product Description

Refractory Concrete

Refractory concrete is a high-performance heat-resistant castable formulated with high-alumina aggregates, refractory powder and special bonding agents.

It features strong high-temperature resistance, excellent structural stability and easy construction on site. With great abrasion resistance and corrosion resistance against high-temperature flue gas and slag, it can maintain stable strength under long-term extreme working conditions.

Widely used for lining repairing and integral pouring of industrial high-temperature furnaces, kilns and thermal equipment in metallurgy, chemical, cement and boiler industries. Safe construction, long service life and reliable refractory protection for various thermal facilities.
 
 

Features

Excellent high temperature resistance, stable performance under long-term high-heat conditions.
Simple construction, easy pouring and on-site molding.
Great thermal shock resistance, not easy to crack during temperature changes.

Strong anti-corrosion and anti-slag ability against flue gas and molten erosion.
High structural strength and wear resistance for long service life.
