混凝土工程配制及施工质量控制

oncrete 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
