摘　　要：砌块结构是常用的建筑结构形式之一.承重型横孔连锁混凝土空心砌块的技术门槛较低,可以在多种建筑施工场景中使用,为了保证其应用后的稳定性,分析了砌体抗压性能.选择QT-250、QH-250、QH-300三种类型砌块作为试件,对照试件的生产尺寸,设定了砌筑砂浆的三种强度类型.采用试压机作为加载受压设备,对砌块砌体进行加压测试,并记录承压数据,以此来分析抗压强度.不同类型试件的抗压强度测试结果表明:不同砌块类型的抗压强度不同,当砂浆强度等级为ER-15、砌块类型为QT-250时,混凝土空心砌体的抗压强度最佳.Block structure is one of the commonly used building structures.The technical threshold of load-bearing cross-hole interlocking concrete hollow block is low,and it can be applied in a variety of building construction scenarios.In order to ensure its stability,this paper analyzes the compressive performance of the masonry.The paper selects QT-250,QH-250 and QH-300 as test pieces and sets three strength types of masonry mortar according to the production sizes.It uses the test press as the loading and compression equipment to test the blocks,records the bearing data and analyzes the compressive strength.The compressive strength test results show that the compressive strength of different types of blocks is different.When the mortar strength grade is ER-15 and the block type is QT-250,the compressive strength of concrete hollow masonry is the best.
