  • 摘要:Concrete quality can be assessed by its ability to withstand its design life without failing, which is a function of its strength and durability. The effect of fly ash (FA)-β- cyclodextrin (β-CD) composite on concrete’s durability indexes was investigated in this paper. Two durability index tests (oxygen permeability and sorptivity) were used for the assessment. FA (30% and 50% by mass of cement), β-CD (0.025%, 0.05% and 0.1%) and FA-β-CD composite were incorporated in the concrete mix. Twenty four different concrete mixes were investigated at 0.5 water-binder ratio (W/B) and 0.4 W/B. The tests were performed on the concrete samples after being cured for 28 and 90 days. The results showed that β-CD and FA-β-CD composite decrease oxygen permeability and sorptivity of concrete when used at optimum percentages.
