Product Description

Sintered porous bricks, crafted by roasting premium coal gangue shale, boast an impressive porosity exceeding 28%. These bricks, with their numerous small pores, are primarily designed for load-bearing walls. Adhering strictly to the GB13544-2011 standard, our bricks offer unparalleled benefits including high alkalinity resistance, superior seismic performance, exceptional strength, and remarkable wear and compression resistance. Moreover, they are lightweight, provide excellent insulation, and exhibit outstanding durability. Featuring an innovative high hole design, these bricks are not only highly efficient but also energy-saving by a remarkable 45%. This advanced design enhances the building's usable area, accelerates construction speed, and minimizes mortar consumption. When used for exterior walls, sintered porous bricks eliminate the need for additional *** prevention or reinforcement measures. They can be directly plastered, significantly cutting down project costs while ensuring the wall surface remains smooth and free from bulging or cracking over time. Sintered porous bricks are the pinnacle of modern wall materials, ideal for the cutting-edge architectural landscape.
