砖混结构在我国是一种最为广泛的建筑结构形式，砖砌体质量尤其是砌体砂浆的抗压强度是衡量砌体施工质量的一个重要参数。在实际施工中，施工单位往往对砂浆的施工质量不够重视，由于无砂浆配合比、不计量、养护不当等诸多因素，致使砂浆强度的离散性很大，加之试块没有按标准? Brick-concrete structure is one of the most extensive forms of building structure in China. The quality of brick masonry, especially the compressive strength of masonry mortar, is an important parameter to measure masonry construction quality. In actual construction, the construction unit often pays less attention to the construction quality of the mortar. Because there are many factors such as mortar mixing ratio, non-metering, improper maintenance, etc., the dispersion of the mortar strength is very large, and the test block is not according to the standard.
