摘要
通过设置不同的冷却介质,利用球体理论第三边界条件,逐一计算计算150mm、80mm和40mm粒径的骨料在初始温度、冷却时长以及冷却厚度相同的情况下,风冷和水冷的降温幅度。根据计算结果,为今后大体积混凝土骨料预冷技术方案的拟定提供参考。
By setting different cooling media and using the third boundary condition of sphere theory,the cooling ranges of air-cooled and water-cooled aggregates with particle sizes of 150mm,80mm and 40mm are calculated one by one under the same initial temperature,cooling time and cooling thickness.According to the calculation results,it provides a reference for the formulation of aggregate precooling technical scheme of mass concrete in the future.
