建筑工程大体积混凝土浇筑与养护措施探讨

Discussion on Pouring and Maintenance Measures of Mass Concrete in Construction Engineering

目前,建筑工程体系得到优化和完善,其中大体积混凝土技术应用效果良好,能够满足高层建筑物及大型基础施工方面的要求。然而,大体积混凝土具有表面系数小、水热化释放集中、内部升温速度快的特征,在实际施工期间时常出现混凝土温度裂缝等质量问题,如不及时处置,会给结构造成严重的隐患,影响建筑物安全。所以,为充分发挥技术优势,预防和减少混凝土温差裂缝等问题的出现,本文对建筑工程大体积混凝土的浇筑与养护技术措施进行探讨,为同类工程提供参考。

At present,the construction engineering system has been optimized and improved.Among them,the mass concrete technology has a good application effect,which can meet the requirements of high-rise buildings and large-scale foundation construction.However,large-volume concrete has the characteristics of low surface coefficient,concentrated hydrothermal release,and high internal heating speed.Quality problems such as concrete temperature cracks often occur during actual construction.If not disposed of in time,it will cause serious hidden dangers to the structure and affect Building safety.Therefore,in order to give full play to the technical advantages,prevent and reduce the occurrence of concrete temperature difference cracks and other problems,this article discusses the technical measures for the pouring and maintenance of large-volume concrete in construction projects to provide references for similar projects.
