Product Description
Sintered porous bricks are made by roasting coal gangue shale, with a porosity greater than or equal to 28%. The pore size is small and the quantity is large, mainly used for load-bearing walls. The product production strictly follows the GB13544-2011 standard and has the advantages of high alkalinity resistance, strong seismic performance, high strength, wear resistance, compression resistance, lightweight, insulation, etc. The product adopts a new high hole design, which is highly efficient and energy-saving by 45%, effectively enhances the building's usable area, improves construction speed, and reduces mortar usage. When using sintered porous bricks for exterior walls, there is no need to adopt any crack prevention or reinforcement measures. It can be directly plastered, which greatly reduces the project cost and ensures that the wall surface does not bulge or crack in the later stage. Sintered porous brick is currently the most ideal wall material in the field of architecture.
