Plastic Refractory monolithic refractories is an important species. With the refractory industry jargon: fire-resistant plastic is used to aggregate and refractory powder, raw clay and the chemical combinations and admixtures, after the preparation of mixing, extrusion into a brick-shaped, and stored in the packaging after a certain time has good plasticity, can be ramming method of construction of a refractory material.
