| Abstract: | The effect of the quantity of flyash inner doped(%) to concrete strength and fluidity was studied in this paper.According to the data obtained from the test,the rule of 28 day strength of concrete doped with flyash was summarized.The relation of the increment of later stage strength of concrete doped with the quantity of flyash added was studied. The 80 MPa high strength and great fluidity concrete can be prepared by 42.5 ordinary Portland cement,extra fine I grade flyash and high quality retarding high effect water-reducing agent. |
