混凝土体积越大,混凝土内部水化热聚焦的就越多,内外散热不均匀和内外约束不一致,便混凝土内部产生较大的温度应力,以及环境、外界温度的变化,混凝土收缩变形等综合作用,容易造成大体积混凝土产生裂缝,影响结构安全。因此本文总结形成一套大体积混凝土施工技术,降低混凝土的内部温度,降低混凝土内外温差,成功有效的防止裂缝产生,保证了混凝土质量。 The bigger the volume of concrete is, the more the hydration heat inside the concrete is focused, the uneven heat dissipation inside and outside and the inconsistency between the inside and the outside constraints, the larger temperature stress inside the concrete, the change of environment and outside temperature, the shrinkage of concrete, Easily lead to cracks in mass concrete, affecting structural safety. Therefore, this paper summarizes the formation of a set of mass concrete construction technology, reduce the internal temperature of concrete, reduce the temperature difference between inside and outside the concrete, the successful and effective prevention of cracks, to ensure the quality of concrete.
