在建筑工程中,砌筑砂浆是使用量比较大的一种材料。根据统计,每平方米建筑面积约需砌筑砂浆0.123立方米、抹面砂浆0.119立方米,配制砂浆所需要的水泥用量占水泥消耗量的25～40％。因此,砂浆的水泥用量是否合理,不但影响工程的砌筑质量,而且是直接影响工程造价的重要问题,而砂浆的水泥用量是否合理与砂浆定额的规定又密切相关。 In construction projects, masonry mortar is a relatively large amount of material. According to statistics, about 0.123 cubic meters of mortar and 0.119 cubic meters of mortar are required for every square meter of building area, and the amount of cement required for preparing mortar accounts for 25 to 40% of cement consumption. Therefore, whether or not the cement content of the mortar is reasonable affects not only the quality of the masonry of the project, but also is an important issue that directly affects the project cost. However, whether or not the cement content of the mortar is reasonable is closely related to the regulation of the mortar quota.
