company news about About unshaped refractory castable

Unshaped refractory castable refractory is bulk shape, is composed of certain refractory aggregate and powder materials, by adding liquidity in bond and water has higher, suitable for pouring and forming some non-standard specifications of refractory products. But some need to on-site pouring pouring way, can control the increase decrease the quantity of water but also can increase the number of adding plasticizer and water reducing agent to promote the condensation nuclei hardening, therefore also often referred to as the material for refractory concrete mixture.

The characteristics of castables are not the only use of alien and difficult part of the variety and quantity of masonry, many properties to a large extent depends on the binders which, at present our country production of refractory castable more categories, from the castable refractory fireclay and high alumina dense have certain specifications and physicochemical index, is mainly used in accordance with customer's different, and choose their own castable products.
