摘要
水泥水化反应导致产生温度变化和收缩作用,大体积混凝土结构极易产生裂缝。本文分析了大体积混凝土裂缝的成因,从设计、材料、施工、养护等四个方面总结了减少大体积混凝土产生裂缝的技术要点,并通过一个工程实例进行了分析与验证。
Cement hydration reaction leads to the temperature change and shrinkage effect,and the mass concrete structure is easy to produce cracks.This paper analyzes the causes of the crack of mass concrete,summarizes the technical points of reducing the crack of mass concrete from four aspects of design,material,construction and maintenance,and analyzes and verifies them through an engineering example.
