Wear resistant cast basalt slab has great advantages in wear resistance. The hardness of wear-resistant cast basalt plate itself is very high, and the Mohs hardness is 1 ~ 2 higher than that of quartz and feldspar. However, the disadvantage is that it has a brittle texture, so it is easy to be pushed and broken in construction. In addition, in construction, the joint between plates is a thin part, and the manufacturers of cast basalt plate have high requirements for bonding process, so the quality is not easy to be guaranteed.
