Loose refractory material (amorphous refractory material): Amorphous refractory material is a refractory material that is composed of reasonably graded granular and powdered materials and binders, and is directly used without forming or firing. Usually, the granular materials that make up this material are called aggregates, the powdered materials are called admixtures, and the binders are called binders. This type of material has no fixed shape and can be made into slurry, mud paste, and loose forms, so it is also commonly referred to as loose refractory materials. This type of refractory material can form seamless integral structures, so it is also called integral refractory material.
The basic composition of amorphous refractory materials is granular and powdery refractory materials. According to its usage requirements, it can be made of various materials. In order to combine these refractory materials as a whole, except for a few special cases, appropriate varieties and quantities of binders are generally added. To improve its plasticity or reduce water consumption, a small amount of appropriate plasticizer and water reducer can be added. To meet other special requirements, a small amount of appropriate other admixtures can also be added separately.
