    关键词：混凝土；配合比设计；问题；防治

    混凝土随着材料科学的不断发展，其用途也越来越广泛，已到了跨行业、跨学科、互相渗透的非常广泛的领域。混凝土配合比设计牵涉到几个方面的内容：一要保证混凝土硬化后的强度和所要求的其他性能和耐久性；二要满足施工工艺易于操作而又不遗留隐患的工作性；三是在符合上述两项要求下选用合适的材料和计算各种材料用量；四是对上述设计的结果进行试配、调整，使之达到工程的要求；五是达到上述要求的同时，设法降低成本。
普通混凝土是由水泥、水、砂、石四种材料组成的，混凝土配合比设计就是解决4种材料用量的3个比例，即水
Mix Design of Concrete Several notable issues

    Abstract: Concrete Design noted several problems in the analysis, and corresponding control measures.
    Key words: concrete; mix design; problem; Prevention

    Materials Science of Concrete With the continuous development of more and more widespread its use has to cross, cross-discipline, mutual penetration of a very wide range of areas. To the concrete mix proportion design involves several aspects: one to ensure the concrete to harden the strength and the required performance and durability of the other; 2 to meet the construction process easy Cao Zuoer not left the work of Xing hidden; third Zaifu He Both request the appropriate choice of materials and calculate the amount of various materials; 4 is the results of the test design with, adjusted to meet the engineering requirements; 5 is to achieve these requirements while reducing costs.
Ordinary concrete is made of cement, water, sand, stone composed of four materials, concrete mix design is to solve the four kinds of materials, the proportion of the amount of the three, that water
