Neutral Refractory

Low Cement Castable

The term "low cement" refers to the reduced amount of cement binder used in the formulation of the castable. Traditional castable contain a significant amount of cement as a binder, which helps hold the refractory aggregate particles together when the castable is installed and cured. However, excessive cement can lead to problems such as reduced high-temperature performance, increased thermal shrinkage, and decreased resistance to thermal shock.

The reduced cement content is typically compensated by using advanced refractory additives that promote particle packing and sintering of the refractory aggregates during the curing process.
