【摘要】：混凝土由于水化温升的影响,结构内部温度与试验室标准养护或同条件养护下留样混凝土试块温度存在较大差别,因此采用留样混凝土强度作为实体构件的抗压强度可能存在较大误差。介绍了采用成熟度理论预测水下封堵用混凝土抗压强度的方法。现场结果表明:与留样相比,采用成熟度理论预测混凝土强度能更加准确地反映混凝土实际抗压强度。
[Abstract]:Due to the effect of hydration temperature rise, the internal temperature of the concrete structure is different from that of the specimen under the standard curing in laboratory or under the same condition. Therefore, there may be some errors in the compressive strength of concrete retaining concrete. This paper introduces the method of predicting the compressive strength of underwater plugging concrete by using maturity theory. The field results show that the prediction of concrete strength by using maturity theory can more accurately reflect the actual compressive strength of concrete than that of retaining samples.
