水泥混凝土是由水、水泥、砂、石四种基本材料外加剂和掺合料组成的。对于没有检测条件的县以下工程单位,或临时组合的施工组织,常套用已有的混凝土配合比例参考资料。怎样才能选用好这类参考资料,既保证工程质量又有较好的经济效益呢? 一、混凝土配合比手册的内容和特点混凝土配合比手册(以下简称《手册》),是根据许多试验和应用资料进行整理编制出来的。由于各次试验和运用的条件不尽相同,难免受到材料差别、地区条件和检验误
Cement concrete is composed of water, cement, sand, stone four basic materials admixture and admixture. For those engineering units below the county level that do not have the testing conditions, or temporary construction organizations, they often apply the existing concrete mix reference materials. How can we choose this type of reference materials, not only to ensure the project quality and better economic benefits? First, the content and characteristics of concrete mix manual Concrete mix manual (hereinafter referred to as “manual”), is based on many tests and applications Information compiled by the preparation. Due to the different conditions of each trial and application, it is inevitable that the material difference, the regional conditions and the test mistakes
