Refractory cement is a material used in the manufacture of refractory castables, with a refractory resistance of not less than 1580 ° C. According to the composition of different can be divided into aluminate cement, calcium aluminate, calcium magnesium aluminate and dolomite. When using purely fire-resistant cement, then a lot of cracks will occur after high temperature, it is necessary to pay attention.

 

Refractory cement and refractory refractory are a kind of fire-resistant cement refractory at 1300 degrees, he has a high strength after condensation, the label can reach 625, mainly mixed with the bauxite aggregate equipment used in refractory high Refractory concrete, fire-resistant refractory soil at 1000 degrees, there is no strength after the coagulation, only play a certain bonding effect, refractory soil is generally used for brick masonry or paste wall furnace.

 

If the fire-resistant cement and refractory soil are used in combination, then the value of refractory cement will be greatly discounted, equivalent to the fire-resistant cement and loess mixed together as one reuse, refractory cement coagulation strength and labeling will be much lower.
