Study on the Influence of Different Dosage of Stone Powder and Fly Ash on the Performance of RCC in Reservoir
Under the condition that the total amount of mineral admixture is unchanged,the difference of strength and performance of RCC with different dosage of stone powder instead of equal proportion fly ash is analyzed experimentally.The results show that the performance of RCC with stone powder replacing part of fly ash is improved,and the VC value of RCC shows a trend of decreasing in the early stage and increasing in the later stage.When the content of stone powder and fly ash is 28%+27%,the performance of RCC is the best.Under the condition that the mixture amount of fly ash and stone powder is 40%+15%,the strength properties of RCC are reduced by less than 20%compared with full fly ash in the whole age period,and the economic benefits of concrete are good and the strength properties are high.
