【摘要】：大體積混凝土裂縫出現(xiàn)有多方面原因,主要原因是水泥水化熱控制不當導致的。本文通過對北京市某住宅樓筏板式基礎大體積混凝土施工實例分析,對大體積混凝土施工中水泥水化熱、外界氣溫變化、混凝土的收縮等因素導致的混凝土出現(xiàn)裂縫有針對性地進行系統(tǒng)分析并提出了解決方案,在實際實施工程中得到較好應用,取得良好效果。
[Abstract]:There are many reasons for mass concrete cracks, mainly due to improper heat control of cement hydration. Based on the analysis of mass concrete construction of raft slab foundation in a residential building in Beijing, the heat of cement hydration and the change of outside temperature during the construction of mass concrete are analyzed in this paper. The concrete cracks caused by shrinkage of concrete are analyzed systematically and the solutions are put forward, which are well applied in practical engineering and obtain good results.
