Abstract：In order to study the influence of particle size of fly ash on the hydration property of silicate gel materials,three kinds of fly ash with different particle size distribution were obtained by grinding with ball mill.The influence of them on the rate and amount of hydration heat,the hydration degree of silicate cement and the hydration degree of themselves was studied.The results show that the hydration activity of fly ash increase obviously,the degree of hydration reaction increase,the hydration degree increase by 20.7％ at 7 d with the decrease of the particle size of fly ash,and reaction on the total amount of hydration heat of silicate cement materials is small.The influence of particle size of fly ash mainly lies in rate of hydration heat and the hydration degree.The hydration degree of cementitious materials increases by 3％ at 28 d.
