为了探讨等效龄期法在预测大体积混凝土力学性能中的应用,该文共设计了5组混凝土配合比和2种养护方式。通过绝热温升实验确定了每组配合比的匹配养护温度,对比了温度匹配养护混凝土的力学性能和等效龄期法换算的标准养护的混凝土力学性能,结果表明:通过等效龄期法推算的混凝土力学性能高于温度匹配养护混凝土的力学性能,等效龄期法在大体积混凝土性能预测中有局限性。
In order to discuss the application of equivalent age method in predicting the mechanical properties of mass concrete, a total of five concrete mix ratios and two curing methods were designed. Through the adiabatic temperature rise experiment, the matching curing temperature of each mixture was determined. The mechanical properties of concrete with temperature matching cured concrete and the standard cured concrete calculated by equivalent age method were compared. The results showed that the equivalent age method Of the mechanical properties of concrete is higher than the temperature matching the mechanical properties of concrete curing, equivalent age method in the performance of large-volume concrete has limitations.
