High Temperature Resistant Good Quality Refractory Material Castable are new castables with a low binder content. The key point is the use of ultrafine particles not exceeding 1 μm. Its thermal shock resistance, slag resistance and erosion resistance are significantly improved, surpassing similar refractory bricks. Further reducing the binder content can produce ultra-low cement castables and cement-free castables
High Temperature Resistant Good Quality Refractory Material Castable refer to castables with lower cement usage. The amount of cement used for refractory cement castables is generally 15% to 20%, and the amount of cement for low cement castables is about 5%, and some even decrease to 1% to 2%. The purpose of reducing the amount of cement is to improve the fire resistance of the castable.
It relies on the addition of several special raw materials to obtain good performance: First, pure calcium aluminate cement, because of the high content of effective mineral CaO·Al2O3, the lesser the incorporation, the desired strength can be obtained. The second silica fume is a glass microsphere having an SiO2 content of between 93% and 98% and an average particle diameter of about 0.5 μm. After the addition of silica fume, the flowability of the castable is good, the water requirement for molding is low, the sintering temperature is low, and the performance after heat treatment is avoided. Third, alumina fine powder, which is relatively easy to participate in the reaction and improve the fire resistance of the material. Fourth, the water reducing agent, which can adsorb on the surface of the powder, thereby generating electrostatic repulsion to disperse the powder, thereby further exerting the function of the fine powder.
