混凝土的绝热温升研究综述

Summarization of research on adiabatic temperature rise of concrete

为了防治混凝土发生裂缝，许多大体积混凝土在设计中提出抗裂要求，绝热温升是混凝土抗裂能力的指标。本文总结了影响混凝土绝热温升的因素，同时提出通过选择水泥品种、掺用掺合料和外加剂、降低养护温度等方法来降低混凝土的绝热温升，从而提高混凝土抗裂性能，为工程实践提供参考。

In order to prevent the crack of concrete, many mass concrete in dams takes adiabatic temperature rise as an important index of crack resistance. In this paper, we analysis the influencing factors and measures of improving it. We can improve the adiabatic temperature rise of concrete by adding admixtures, additions, and decreasing curing temperature, which can improve crack resistance of concrete and can be used as reference in project.
