self-flow castable, It could be applied in narrow environment where is not vibrate(if possible, it could be rammed by person).

Description

Self-flow castable
This product use synthetic materials including high-quality bauxite, corundum and silicon carbide which are proceeded by specific equipment, as the main material, compound with many admixtures and high-efficient water reducing admixture ,and fluidizing admixture to improve the workability.
 
The main characters are: it could be applied in narrow environment where is not vibrate (if possible, it could be rammed by person), only rely on its deadweight and push by the potential energy without vibration. It has good construction and quality performance, and is mainly used in circulating fluidized bed boiler furnace lining and other construction sites in the furnace lining which are hard to implement.
 
Main physical and chemical characteristics:
