Brief introduction of lightweight castables

Lightweight acid-resistant castables are composed of lightweight aggregates, powders, binders and additives, and the main component of the binder is water glass. The lightweight aggregate structure has a large porosity, a rough surface, and a particle size of about 5mm. The aggregate and powder have high water absorption and hygroscopicity, and poor fluidity after mixing according to the mix ratio. The product has good physical and chemical properties, with low bulk density, fast solidification when adding water, high operating temperature, compressive strength increases with the increase of temperature and acidity, الموصلية الحرارية المنخفضة, and low linear expansion coefficient.

Characteristics of acid-resistant castables

Lightweight: The castable uses lightweight aggregates or additives such as foaming agents to give it a lower density, thereby reducing the deadweight of the structure. This helps to reduce equipment load and reduce energy consumption.

Acid resistance: Lightweight acid-resistant castables use special aggregates and binders with good acid resistance. It can resist the erosion of acidic media and maintain the stability and durability of the structure.

Temperature resistance: The castable has a certain high temperature resistance and can maintain the stability and performance of the structure in a high temperature and acidic environment.

Easy construction: Lightweight acid-resistant castables have good castability and plasticity, and are suitable for structures of various shapes and sizes. It can be constructed by pouring, spraying, إلخ., which is convenient for coating and maintenance of complex structures.
