我国现行的《普通混凝土配合比设计技术规定》(JGJ55—81)中,提出了配合比设计的基本原理和方法,并提供了组成材料性质及其不同用量比例,与混凝土性质问关系的参考数据表。在掌握组成材料的各项性质后,即可从这些参考数据表中,查得相应的有关数据,按规定方法,计算确定初步配合比。在这一过程中,除规定使用的公式外,还必须依靠这些数字繁多的数据表,而且从表中还不能直接查出所需数据,需要通过内插求得;还有某些因素的影响,表中数据未
China’s current “Technical Regulations for Design of Mixing Ratios of Normal Concrete” (JGJ55-81) proposes the basic principles and methods of mix ratio design, and provides reference data on the nature of the constituent materials and the ratio of their use, and the relationship between the properties of concrete and concrete properties. table. After grasping the properties of the constituent materials, relevant data can be obtained from these reference data tables, and the initial mix ratio can be calculated and determined according to the prescribed method. In this process, in addition to the prescribed formulae, it is also necessary to rely on these numerous data tables, and the required data cannot be directly identified from the table, and it needs to be obtained through interpolation; there are also some factors that influence , The data in the table is not
