Abstract-The strength, anti-carbonation resistance and steel corrosion resistance properties of high volume fly ash concrete are studied in this paper. The results show that the strength of concrete for 28d is higher than that of normal concrete, as well as the anti-carbonation resistance, when the mixing amount of fly ash is 30% and 40% and the W/B is below 0.4. The anti-carbonation resistance of...
This paper discusses reactivity and high-strength mechanism of modified fly ash concrete by DSC, SEM and DTA. The result indicates the shape effect, activation effect and micro-aggregate effect of the modified fly ash is developed sufficiently. The reactivity of modified fly ash concrete is enhanced obviously. The binder material of modified fly ash hydration heat is much more than the original fly...
