| 摘 要： | 为了探究粉煤灰掺量对补偿收缩混凝土的强度和限制膨胀率的影响规律,通过对掺有不同粉煤灰掺量的补偿收缩混凝土与基准混凝土进行对比试验研究,得出了能使补偿收缩混凝土达到最大膨胀率的粉煤灰的最优掺量为30%,并得到粉煤灰掺量与补偿收缩混凝土的强度和限制膨胀率的基本规律并对此作了一定的理论分析。

| Abstract: | In order to explore the influence rule of the dosage of flyash on the strength and restrictive expansion rate of the shrinkage-compensating concrete, the shrinkage compensating concrete which was mixed with different dosages of fly ash was compared with the normal concrete. The test results show that, the optimal dosage of fly ash is 30% which is aimed to maximize the expansion and contraction rate of shrinkage-compensating concrete. Besides , the basic laws between the dosage of fly ash and the strength, the restrictive expansion rate of shrinkage compensating concrete are summarized, and some theoretical analyses were carried out. |
