Grade 23

Grade 23

Lightweight bricks generally refer to foamed bricks. Normal indoor partition walls use such bricks to effectively reduce the load on the floor and the sound insulation effect is good. The high-strength plate-shaped corundum and mullite are used as the aggregate, and the sillimanite is used as the matrix. The special additive and a small amount of rare earth oxide are mixed, and the mixture is formed by high pressure molding and high temperature....
