Low Cement Castable

Print
Low cement castable, low porosity rate, high density, high compressive strength, high refractories under load.

Description

Low cement refractory castable has the merits of high density, low porosity rate, good hot strength, high refractories and high refractoriness under load. It is strong in mechanical spalling resistance, shock resistance and corrosion resistance. This product is widely used in thermal equipments, heating furnace in metallurgical industry, boilers in electricity industry, and building material industry furnace.
