烧结多孔砖的孔洞多与承压面垂直，它的单孔尺寸小，孔洞分布合理，非孔洞部分砖体较密实，具有较高的强度。
The holes of sintered porous brick are mostly perpendicular to the bearing surface. The single hole size is small, and the hole distribution is reasonable. The non hole part of brick is dense and has high strength.
普通烧结砖有自重大、体积小、生产能耗高、施工效率低等缺点，用烧结多孔砖和烧结空心砖代替烧结普通砖，可使建筑物自重减轻30%左右，节约粘土20%～30%，节省燃料10%～20%，墙体施工功效提高40%，并改善砖的隔热隔声性能。通常在相同的热工性能要求下，用空心砖砌筑的墙体厚度比用实心砖砌筑的墙体减薄半砖左右，所以推广使用多孔砖和空心砖是加快我国墙体材料改革，促进墙体材料工业技术进步的重要措施之一。
Ordinary fired brick has the disadvantages of heavy weight, small volume, high energy consumption and low construction efficiency. The replacement of fired ordinary brick with sintered porous brick and fired hollow brick can reduce the weight of building by about 30%, save clay by 20% - 30%, save fuel by 10% - 20%, increase the construction efficiency of wall by 40%, and improve the thermal insulation and sound insulation performance of brick. Generally, under the same thermal performance requirements, the thickness of the wall built with hollow brick is about half as thin as that of the wall built with solid brick. Therefore, the popularization of porous brick and hollow brick is one of the important measures to accelerate the reform of wall material in China and promote the technological progress of wall material industry.
