在《砌体工程施工及验收规范》(GB50203—98)和《建筑工程质量检验评定标准》(GBJ 301-88)中,对砌砖工程的质量检验和评定的方法,都侧重于砖的品种、强度等级符合设计要求;砂浆品种必须符合设计要求,强度必须符合评定要求;砖砌体水平灰缝砂浆的饱满度及留槎必须符合施工规范规定等。但却未提出砌体的强度必须符合设计要求。一、对砂浆和砌体的分析有人说砂浆是没有粗骨料的混凝土,经常误把混凝土的理论误用于砌筑砂浆。事实上,砂浆在工作度、砌筑、养护环境等方面不同于混凝土。砌筑砂浆不是—个结构单元体。
In the “Code for Construction and Acceptance of Masonry Construction” (GB50203-98) and “Construction Engineering Quality Inspection and Assessment Standards” (GBJ 301-88), the methods of quality inspection and assessment of brickwork are all focused on the varieties of bricks , The strength level meets the design requirements; mortar varieties must meet the design requirements, the intensity must meet the assessment requirements; brick masonry level mortar joints full and mortar must comply with the provisions of the construction code. However, the strength of the masonry has not been raised to meet the design requirements. First, the analysis of mortar and masonry Some people say that mortar is a concrete without coarse aggregate, mistakenly put the theory of concrete mistaken for masonry mortar. In fact, mortar differs from concrete in terms of workability, masonry, conservation environment and the like. Masonry mortar is not a structural unit.
