Description of self-flowing refractory castables for suitable binders and water reducers

Self-flowing refractory castables are generally formulated using low cement technology. Aluminate cement is commonly used as a binder, and its variety and amount are different, and the water demand is also different. The variety, quality and amount of ultrafine powder are different, and the water demand is also different. To this end, the variety and amount of aluminate cement and ultrafine powder should be reasonably selected to meet the demand for self-flowing refractory castables.

The self-flowing refractory castable has many matrix materials and requires a large amount of water, so it is very important to select a high-efficiency water reducing agent. Water reducing agents generally use a variety of inorganic or organic water reducing agents, used alone or in combination. Adding water reducing agent can reduce the water demand of cement, fully disperse the ultrafine powder and fully fill and improve the denaturation effect. At the same time, the excess water is released from the agglomerates formed by the matrix to become free water and reduce the mixture. Viscosity allows the castable to flow freely.
