Alkali Resistant Agent Alkali Suppression Alkali Inhibitor For Cement Mortar Plaster YJ-1

A well-known problem in a concrete production is the alkali–silica reaction which can result in the abnormal expansion and cracking of concrete. Typically, this reaction is due to a reaction between hydroxyl (OH) ions normally associated with alkalis (Na2O and K2O) in the cement and silica minerals in the concrete mix.

Alkali inhibitor is a kind of material containing amorphous highly active silica and high adsorbent. When added to the product of cement dry powder mortar system, it can significantly reduce the content of free calcium hydroxide in the material and inhibit the occurrence of efflorescence on the surface of cement mortar. , fundamentally solve the problem of efflorescence in building materials.

The recommended addition amount is 0.3%-0.8% of the total gelling material, which can effectively inhibit surface efflorescence and achieve good use effects.
