摘要

摘要: 煤矸石烧结复合保温砌块是集围护和保温于一体的一种新型墙体材料。为了掌握这种材料的力学性能，开展了煤矸石烧结复合保温砌块的力学性能进行试验研究，分析三种不同受压状态下砌体的抗压强度和抗折强度。研究表明：复合保温砌块的不同受压面的抗压强度存在较大差异，表现为承载面受压时最大，榫受压时面最小；复合保温砌块的抗折强度受自身裂缝的影响，折压比分散性较大；复合保温砌块的抗压性能符合GB/T 29060—2012《复合保温砖和复合保温砌块》和GB 50574—2010《墙体材料应用统一技术规范》中对砌块强度等级的要求。

Abstract: Coal gangue sintered composite insulation blocks are new type of wall materials,which integrated the building enclosure and heat preservation. To grasp the mechanical properties of the blocks, tests were conducted, and the compressive strength and flexural strength on three different compression surfaces-the bearing surface, the front and surface of the joint tongue and groove were analyzed. The results showed that the compressive strength on different compression surfaces of composite insulation blocks was different obviously, the strength was the largest for the bearing surface, and the strength was the smallest for the surface of the joint tongue and groove. The flexural strength of composite insulation blocks was affected by its own cracks, and the ratios of bending-compressive strength were more dispersive. The compressive performances of the composite insulation blocks could meet the requirements for the strength grade of the blocks in the bricks & blocks composited insulation materials(GB/T 29060-2012) and the uniform technical code for wall materials used in buildings(GB 50574-2010).
