一、前言提高混凝土工程质量(特别是体积较大的工程)是采取选用高标号水泥或增加单位水泥用量,还是采用其它的方法,是值得探讨的一个问题。作者认为,提高混凝土工程质量,应在许可的条件下选用最大粒径的粗骨料,通过试验求出粗骨料的最大容重,选择合适的外加剂和掺合料,在满足施工要求的情况下,把混凝土中的水泥用量降到最低值。 First, the preface To improve the quality of concrete engineering (especially large-scale projects) is to choose to use high-grade cement or increase the amount of cement per unit, or using other methods, is worth exploring a problem. The authors believe that, to improve the quality of concrete works, the maximum particle size of coarse aggregate should be selected under the permitted conditions. The maximum bulk density of coarse aggregate should be determined through experiments and the proper admixture and admixture should be selected to meet the construction requirements Under the concrete in the amount of cement to a minimum.
