In recent years, the demand for industrial and civil buildings in massive concrete more and more. Because of its large volume, small surface, cement hydration heat release is relatively concentrated, the internal temperature more quickly, when the concrete temperature difference is large, the temperature will produce concrete cracks affect the structural safety and proper use, it is necessary to analyze the underlying it is to ensure the quality of construction. This paper describes the mechanism of mass concrete cracks, and made from the material means of control, design and construction aspects.
