大体积箱梁混凝土水化热研究

Research on hydration heat of large volume concrete structure

大体积混凝土水化放热导致结构早期开裂是工程中必须重视的问题。本文以某大体积混凝土箱梁为实例,通过分析水化热对箱梁温度的影响,探究箱梁温度变化规律,并提出一系列温度控制措施,以确保大体积混凝土施工质量。

Temperature cracks in large volume concrete structure caused by hydration heat is a key issue that must be paid attention to in engineering.To ensure the quality of large volume concrete structure,this paper analyzed the influence of hydration heat on temperature of large volume concrete structure.This paper also explored the law of temperature change of concrete structure.What s more,a series of temperature control measures were proposed to reduce the influence of hydration heat on large volume concrete structure.
