| Abstract: | Through the experiments, pore structure characteristic, the expanding and changing of pore structure with age period and the effect of high pressure water to pore structure of RCC(Roller Compacted Concrete) made with high volume fly ash were researched. The factors of RCC mix proportion and age affecting pore structure were disscussed, the permissible fly ash content of RCC used on has been exploned. |
