What are the differences between wear-resistant castable materials and wear-resistant plastics?

Wear-resistant castable and wear-resistant plastic have a common characteristic: both are amorphous refractory materials with high wear resistance. Therefore, it is easy for customers to confuse them when purchasing, which may lead to serious consequences during later use. So, how can we differentiate between wear-resistant castable and wear-resistant plastic? What are the differences between the two?

1. There's a significant difference in the construction methods for the two materials.

During the installation of wear-resistant plastic, material binding is required. Due to the plasticity of the plastic, whether formwork is needed depends on the construction object. Support pieces such as turtle net, anchor bolts, and anchor bricks can be used instead. The material is placed into the gaps of the support pieces and compacted. It is worth noting that wear-resistant plastic should not come into contact with water during construction, and waterproofing measures for the construction object must also be taken.

Before construction, the wear-resistant castable is mixed with the binder from the bag in a forced mixer and water is added to stir. During the construction process, formwork must be set up, and support elements such as anchor bolts and anchor bricks are laid. Perform the casting and vibration for compaction. After the material has cured, remove the formwork and dry-cure.

2. Regarding raw materials and binders

The wear-resistant castable is primarily composed of raw materials such as brown fused alumina, silicon carbide, and homogenized bauxite, which possess high strength and excellent resistance to wear, serving as refractory aggregates and powders. For binder selection, cement is chosen for the wear-resistant castable. Additionally, chemical admixtures are added to enhance its wear resistance.
