Refractory mortar, also known as high-temperature mortar, can be used to resist high-temperature environments. It is a special type of mortar designed for high-temperature applications where ordinary mortar cannot withstand extreme heat. Refractory mortar is composed of refractory powder, binder, and admixture with a certain particle ratio, poured into water or liquid binder to make a paste. Refractory mortar can be made into powder, and the smallest size can be less than 1mm, and some are even less than 0.5mm. Refractory mortar has high sealing performance and high corrosion resistance. According to different components, it can be divided into clay mortar, high alumina mortar, silicon mortar, magnesia mortar, and so on.

Clay refractory mortar is made of calcined clay together with raw materials and additives. Clinker is the main component of clay refractory mortar, the content is about 75%~80%. As a joint material, clay refractory mortar can adjust the size deviation of bricks and play an important role in masonry structure.
Silica refractory mortar is a refractory mortar made of silica powder, clay, admixtures, and binders mixed in a certain particle ratio. Silica mortar has the advantages of acid resistance, high heat resistance, low thermal conductivity, and good bond strength. Silica refractory mortar is mainly used in the masonry and repair of industrial kilns such as hot blast furnaces, coke ovens, and glass furnaces built of silica bricks.
High alumina mortar is made of high alumina cement and high alumina aggregate, with alumina content over 60%. The refractoriness of high alumina mortar is above 1500℃. High alumina refractory mortar is mixed with water to form a paste for laying and bonding shaped refractory products, such as refractory bricks. Our high alumina refractory mortar is the best choice for high temperature fireplaces, ovens, kilns, furnaces and chimney construction.
1. Metallurgical industry: used to line blast furnaces and ladles, protecting them from extreme high temperatures.
2. Ceramic industry: used to seal and connect kiln components.
3. Power plants: used for boiler repair and maintenance.
