摘要
煤矸石烧结复合保温砌块是一种节能型墙体材料,具有轻质、高强和保温性能好等优点。为了研究煤矸石烧结复合保温砌块砌体的受压性能,通过对2组共12个试件的煤矸石烧结复合保温砌块砌体进行研究,分析煤矸石烧结复合保温砌块与普通砂浆砌体以及与石膏砂浆砌体试件的破坏特征和受力性能。研究表明:煤矸石烧结复合保温砌块的局部破坏导致砌体试件整体失稳破坏,砌体的抗压强度小于砌块的抗压强度,且试验值小于GB 50003—2011《砌体结构设计规范》中的计算值。根据试验实测数据,得出应力-应变关系曲线,经过分析对比提出砌体的应力-应变关系建议表达式和弹性模量的建议值。
Coal gangue sintered composite insulation block is a kind of energy-saving wall material,which has the advantages of light weight,high strength and good insulation performance. In order to study the compression performance of coal gangue sintered composite insulation block,two groups of 12 specimens of coal gangue sintered composite insulation block masonry were studied,and the failure characteristics and mechanical properties of sintered gangue composite insulation block and ordinary mortar and gypsum mortar masonry specimens were analyzed. The results showed that the local failure of sintered gangue composite insulation block caused the overall instability and failure of the masonry specimen,the compressive strength of the masonry was less than that of the block,and the test value was less than the calculation value in GB 50003-2011. Based on the test data,the stress-strain relation curve was obtained,and the proposed expression of stress-strain relation and the recommended value of elastic modulus of masonry were proposed through the method of analysis and comparison.
