  Refractory castable is a kind of granular and powdery material made of refractory materials, which is composed of a certain amount of binder and water
It has high fluidity and is suitable for pouring construction
Refractory castable is the main variety of amorphous refractory materials
According to the different cements used, its curing and forming mechanism can be divided into hydraulic, pneumatic and fire hardness
1
Hydraulic castables: castables with cement as binder need water to participate in chemical reaction in the hardening process to form cementitious hardening strength
They are hydraulic fire-resistant castables
Cement is the main factor determining the strength of castable (especially the strength at room temperature), but its fire resistance is relatively low
Therefore, after ensuring the necessary strength at room temperature, the amount of cement should be reduced as much as possible
If it is necessary for compactness and workability of construction, the refractory powder can be added appropriately
Reducing the amount of cement is also one of the measures to reduce the cost
During construction, the mixing of aluminate cement with Portland cement and lime shall be strictly prevented
Because the mixture of these two substances with different chemical components will produce aqueous tricalcium aluminate, which greatly reduces the strength
2
Pneumatic castable: it refers to that its cementitious agent absorbs CO2 in the air during curing and gradually solidifies and hardens
Water glass refractory concrete is commonly used in castables
In addition to high temperature resistance, water glass castable also has acid resistance and wear resistance, so it is often used as the lining of chemical equipment
3
Fire resistant castable: castable with phosphoric acid and phosphate as binder can obtain strength and high temperature performance only after heating and baking, so it is called fire resistant castable
Generally, when using refractory castables, we need to comprehensively select the types according to the environmental conditions and other aspects, so that the materials that can be selected in the later stage can meet the use needs and the construction can be more convenient and fast The company's website provides product pictures and product materials
