大体积混凝土施工的温控措施

对于大体积混凝土建筑，水泥水化热引起混凝土浇筑内部温度和温度应力剧烈变化，是导致混凝土发生裂缝的主要原因。根据我国大体积混凝土结构的施工经验．为防止产生温度裂缝，应着重在控制混凝土温升、延缓混凝土降温速率、减少混凝土收缩、提高混凝土极限拉伸值、改善约束和完善构造设计等方面采取措施，而混凝土温升的控制尤为重要，本文着重对此进行了论述。

Construction of Mass Concrete Temperature Control Measures

For mass concrete construction, cement caused by hydration heat of concrete pouring temperature and internal stress of dramatic changes in temperature, is the main reason for cracks in concrete occur.According to the structure of mass concrete construction experience, in order to prevent temperature cracks in the concrete should be focused on in the control of temperature rise.Slow cooling rate of concrete.To reduce shrinkage.To enhance the value of ultimate tensile concrete.To improve the binding and impro...
