摘　　要：按照国家标准GB/T50315—2011中规定的筒压法操作流程,对混凝土砖及混凝土小砌块砌筑水泥砂浆的现场检测方法进行了试验研究。通过对自然养护条件下水泥砂浆试块立方体抗压强度与墙体砌筑砂浆筒压比的相关分析,认为国标GB/T50315—2011中关于烧结砖砌筑水泥砂浆的测强曲线不适用于混凝土砖及小砌块砌筑水泥砂浆,并提出了新的测强曲线。According to the operational processes of the method of compression in cylinder in the national standard GB/T50315--2011, the method for site testing of concrete brick and small concrete block masonry cement mortar is researched. Through the correlation analysis about the cube compressive strength of cement mortar test block and cylinder pressure ratio of masonry mortar in wall in natural curing conditions,the strength curve for masonry cement mortar in sintered brick wall in the national standard GB/T50315--2011 does not apply to concrete brick and small concrete block masonry cement mortar,and a new measurement curve is put forward.
