大体积混凝土主要是指混凝土结构长、短边中短边的长度大于等于1m的结构,或者混凝土结构横断面较大,同时大体积混凝土内部主要有构造筋和配筋,钢筋分布较密。在混凝土浇筑完成后,内部易产生大量的热量,且内部热量释放的速度较慢,结构表面易出现裂纹。大体积混凝土常见的问题1.温度裂缝在浇筑混凝土施工结束后,由于建筑结构体积较一般混凝土结构体积大,其在水化硬化过程中,混凝土结构内部会释放出大量的热
Mass concrete is mainly refers to the structure of long and short sides of the short side length greater than or equal to 1m structure, or larger cross-section of concrete structure, while the mass concrete mainly has the structure of internal reinforcement and reinforcement, steel distribution more dense. After the pouring of concrete is completed, a lot of heat is easily generated in the interior, and the internal heat is released slowly, and the surface of the structure is easily cracked. Common problems of mass concrete 1. Temperature cracks After the construction of pouring concrete is finished, due to the volume of building structure is larger than that of ordinary concrete structure, during the process of hydration and hardening, a lot of heat is released inside the concrete structure
