High Strength Alkali Resistance Castable

 High Strength Alkali Resistance Castable

【Product brand】GT-13NL

【Recommended use】 Preheater and Cool Zone of Grate Cooler

Product Introduction

Main Performance Characteristics:

(1) The product uses high-silica, low-alumina alkali-resistant raw materials as aggregates. When exposed to alkali gas erosion during use, the high-silica, low-alumina components react with the alkali gas to form a high-viscosity liquid phase, preventing alkali erosion and enhancing the material’s alkali resistance.

(2) The addition of ultra-fine powder results in high material strength.

(3) The product offers good flowability during construction, making it easy to apply.
