Refractory mortar

Description:

Refractory mortar is an unshaped refractory material used as a joint of refractory masonry, also known as joint material. It is composed of a certain proportion of refractory powder and a binder and an admixture, and is adjusted into a slurry by adding water or a liquid binder. According to the characteristics of bonding agent hardening, it can be divided into hydraulic refractory mortar, hot hard refractory mortar and gas refractory mortar.

Advantages:

Used to masonry and repair refractory bricks or refractory products of the same or similar materials

Application:

Joint of refractory masonry, repairing patch
