—vŽ| In this study, the effects of types and activation time of alkali activators on pozzolanic reaction of the paste with 0% and 40% replacement of fly ash were investigated by examining the Ca(OH)2 content and the pore volume. The results showed the presence of alkali activator decreased the Ca(OH)2 content, total and 20-330 nm ranged diameter pore volume, whereas it increased the 3-20 nm ranged diameter pore volume of fly ash cement paste. The alkali-injected starting time 1 month after casting was more effective in reducing 20-330 nm ranged diameter pore volume than 3 months after casting.
