施工企业需要建立自控试验室,每层砌体作业前,根据试验配合比,材料实际状态、性质,确定出合理的砂浆施工配合比,并配专职计量人员按重量比进行计量。(1)制作砂浆时应采用重量比。施工时不考虑材料实际含水状态、性质,不调整施工配合比,仍按试验配合比施工,甚至按体积比施工,这 Construction companies need to establish self-controlled laboratory, before each layer of masonry work, according to the test mix, the actual state of the material, nature, to determine a reasonable mix of mortar construction, and with full-time measurement personnel by weight ratio measurement. (1) the weight ratio should be used when making mortar. Construction does not consider the actual state of water content, nature, does not adjust the construction mix, still according to the test with the construction ratio, or even volume ratio construction, which
