| Abstract: | Taking the engineering practice of large volume concrete pouring for the main structure in new development area in Shenzhen as an example, the paper discusses the problems relating to large volume concrete, excessive temperature difference of hydration heat, temperature stress prone to cause cracks and other difficulties. It puts forward some measures to avoid concrete cracks, and improve the concrete quality in large volume concrete construction from the aspects of concrete raw materials, mixing proportion design and other construction measures. |
