混凝土工程配制及施工质量控制
首发时间:2009-06-30
摘要:混凝土由于自身的特殊性能在水利水电工程、桥梁工程等土木工程领域发挥着极其重要作用。严格禁止与其它品牌水泥混合使用,不同等级水泥之间以及旋窑与机立窑水泥之间都不得混合使用,以免影响混凝土性能。混凝土所用水、砂、石经检验应符合使用标准,避免用污染水及带有污泥的砂、石来配制混凝土。对普通结构混凝土,应控制合理的水灰比。其中水泥、砂、石子、水之间的比例,应根据不同的要求,设计合理的混凝土等级配合比。论述混凝土工程在施工中各工艺流程:混凝土材料,混凝土配合比,混凝土拌制和输送,混凝土浇筑、养护及拆模等工艺流程及其全程质量控制。

Preparation of concrete works and construction quality control
Abstract:Concrete as a result of the special properties of its own in water conservancy and hydropower projects, the field of bridge engineering, civil engineering, such as an extremely important role to play. Trictly prohibited with other brands of cement mix, as well as between different grades of cement rotary kiln and shaft may be between the cement mix so as not to affect the performance of concrete. Concrete by water, sand, stone by using a standard test should be consistent with and avoid using contaminated water and sludge with sand, stone to the preparation of concrete. The general structure of concrete, water-cement ratio should be kept reasonable. One of cement, sand, gravel, water ratio should be based on different requirements, design a reasonable level of concrete mix. Concrete works on the process in the construction: concrete materials, concrete mix, concrete mixing and distribution, concrete pouring, such as conservation and quality control process and the whole
