Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a novel wall material, hydroxy-phosphomolarite, and a preparation method of the novel wall material, hydroxy-phosphatic-magnesia. Background technique [0002] As the enclosure component with the largest surface area in the building structure, the wall not only bears the combined effect of external horizontal loads, but also has the function of blocking the heat exchange between indoor and outdoor. Therefore, high-quality wall materials should have good bearing capacity, excellent durability, impact resistance and deformation resistance. However, at present, my country's wall material products are mainly brick walls, including ordinary clay bricks, clay porous bricks, clay hollow bricks, lime-sand bricks, coke ballast bricks, etc. However, brick walls have weak sealing performance, poor thermal insulation performance, and high resource consumption. [0003] In addit...
