Problems solved by technology

[0002] Currently, solid clay bricks, cement mortar lattice bricks, aerated concrete blocks, foam concrete blocks, etc. are mainly used as wall materials. However, these materials not only consume a lot of natural resources such as clay, cement, aggregate, etc. , high water absorption, high thermal conductivity and other defects, which do not meet the performance requirements of modern building materials such as light weight and heat preservation, so it is urgent to develop new wall materials
