摘要
对不同养护温度条件下的混凝土绝热温升进行了研究 ,用化学反应速率描述时间和温度对混凝土绝热温升的影响 ,用反演分析中的最小二乘法回归分析实验数据 ,探讨了化学反应速率与养护温度之间的关系及用等效时间表示的混凝土绝热温升公式。
This paper presents an experimental study on the adiabatic temperature rise of concrete under different curing temperatures, and the effects of time and temperature on the adiabatic temperature rise are embodied by chemical reaction rate. The experimental data by least two-multiplication method regression analysis by in reverse analysis is adopted to study the relations between chemical reaction rate and curing temperature, as well as the concrete adiabatic temperature rise formula is expressed by equivalent time.
