大体积混凝土的施工技术及质量控制

阐述了大体积混凝土常见的质量问题就是混凝土结构产生裂缝，为了防止裂缝，不仅要满足强度等级、抗渗要求等，还要严格控制大体积混凝土内部最高温度和内外温差，从原材料的质量控制、施工措施、温控手段三方面探讨了大体积混凝土施工技术，以期达到提高大体积混凝土质量的目的。

Construction technology of large bulk of concrete and its quality control

It illustrates the common quality problem of large bulk of concrete is the crack on concrete structure.To prevent crack,not only the strength class and leakage-proof requirements should be satisfied,but also the highest inner temperature and the exterior-interior temperature difference of large bulk of concrete should be strictly controlled.It discusses the construction technology of large bulk of concrete from the quality control of raw materials,construction measures and temperature control methods,so as to achieve the goal of improving the quality of large bulk of concrete.
