DISPERSING ALUMINA

Description du produit

Dispersing agents are commonly used to de-agglomerate the fine particles of the matrix. The matrix of refractory low cement castables contains fine and ultra-fine particles such as calcium aluminate cement, reactive aluminas and silica fume. It is essential that all the matrix components are homogeneously distributed during mixing with water to take full advantage of the optimized particle size distribution, and achieve the lowest water demand and desired rheological behavior.

Caractéristiques du produit

• A unique feature of Almatis dispersing aluminas is the possibility of adjusting the setting time of castables, according to specific placement requirements and climatic conditions, without sacrificing the final strength development as is the case for other common additives for set control.
