浅谈基础建设结构混凝土质量的控制（Elementary discussion on quality control of concrete for foundation construction） Elementary discussion on quality control of concrete for foundation construction [Abstract] in the infrastructure project of the country, the quality of concrete directly affects the safety of building structure, building structure and belongs to the nations long-term goal, a bit sloppy. In addition, the cost of concrete in the total cost of construction occupies a large proportion, in ensuring the quality of the premise, but also trying to reduce costs and create economic benefits. Therefore, how to grasp the main factors influencing the quality of concrete in construction, effective control of the construction quality, and save the limited resources of the country, but also enable enterprises to obtain economic benefits, and can promote the development of Chinas concrete construction technology and other aspects, is the need to put in front of us urgent task. The concrete is a kind of performance of diversified materials composed of cement, sand, stone, water, additives and other ingredients, its performance is not only a direct relationship with the composition of the material, but also with the concrete construction technology, the environment and maintenance conditions are. So we should meet the design and specification from requirements, optimize the construction scheme and strengthen the control of concrete construction management, including the procurement of raw materials selection, optimization design of the mixture ratio, mixing machine selection and measurement control, road transport machinery selection, transportation of concrete unloading method, reasonable pouring construction site the order of arrangement, concrete vibrator, curing, demoulding control and acceptance of maintenance needs, construction units, design units, supervision units, construction units and other departments to manage, and ensure the quality of concrete to meet the requirements of
