摘要
为研究大体积机制砂混凝土水化升温规律,采用DUCOM-COM3数值模拟平台进行了模拟分析。结果表明浇筑温度相对养护温度对大体积混凝土水化升温的影响大许多,且在一定程度上养护温度的影响甚至可以忽略。另外,相同条件下大体积机制砂混凝土内部温度要低于大体积河砂混凝土。
In order to study the law of hydration heat release of crushed sand massive concrete, a simulation analysis was carried out using the DUCOM-COM3 numerical simulation platform. The results show that the pouring temperature has a much greater impact on the hydration heat release of massive concrete than the curing temperature, and the impact of the curing temperature can even be ignored at a certain extent. In addition, the internal temperature of crushed sand massive concrete is lower than that of river sand massive concrete under the same conditions.
