Monolithics refractory product
Monolithic refractory materials, also known as bulk refractory materials or amorphous refractory materials, refer to those refractory materials that are not formed by firing. Unlike traditional shaped refractory bricks, unstructured refractory materials do not have a fixed shape or size. They usually exist in the form of powder, granules, mud, or fibers. When used, they are directly poured, rammed, sprayed, applied, or filled at the construction site according to the needs.
