Refractory mortar is also called mortar or seal jet, which can resist high-temperature environments and is adopted as castable refractory to build and repair all kinds of furnaces and kilns. fire clay mortar is made of refractory powder, binding agent, and admixture., which can be made to be a powder that is used to mix castable refractory mortar. and fireclay mortar also can balance the expansion between firebricks. Thus, only high-quality fireclay mortar can prolong the service life of furnaces and kilns.

How to construct refractory mortar?
Refractory mortar is composed of refractory aggregates, binders, and admixtures, and is the joint material for molded products. Depending on the delivery status, there are two types: dry type and wet type. During construction, add the modulating fluid (water or other liquid) to the specified consistency, and use a spatula or special machinery (such as pressure grouting machinery) to build or grout.
