大体积抗渗混凝土的配合比设计

The mixing proportion design of big volumed anti-seepage concrete

论述了设计大体积混凝土配合比的设计思路 ,对混凝土水化热、收缩原因进行了分析 ,提出了相应的解决方法 ,并对不同的方法进行了分析对比。针对工程的特点选择了适宜的方法。另外还对混凝土原材料选择一一进行了详细的论述 ,并给出其理论依据。解决了混凝土的水化热、收缩、抗渗。

The paper discusses the design thoughts about the mixing proportion of big volumed concrete. The causes of concrete's heat of hydration and contraction are analyzed even the corresponding settlement methods are offered and compartment analysis is made. The appropriate method is selected according to the feature of projects exposed project.In addition, the writer discusses the choice of concrete's raw materials in detail and offers its theoretical foundations. The paper solves the problems such as concrete's heat of hydration, contraction, anti seepage, pumping, etc.
