    Abstract: Studies on the modification of the hydration products of fly ash (FA), β-cyclodextrin (β-CD) and fly ash-β-cyclodextrin (FA-β-CD) composite cement paste samples as hydration progressed were done using X-ray diffraction analysis, scanning electron microscopy and Fourier transform infrared spectroscopy. This paper investigates the effect of FA, β-CD and FA-β-CD composite on the hydration and pozzolanic reactions. It was evident from all the analyses that β-CD improved the hydration reaction from the 7  day hydration period, while improvement on pozzolanic reaction was revealed from the 28  day hydration period. The study contributed to the knowledge of FA performance as a composite with cyclodextrin and promoted the continued inclusion of FA in concrete.
