微粉砕フライアッシュを混合したモルタルの圧縮強度およびポゾラン反応に及ぼす初期高温養生の影響

抄録

Compressive strength and pozzolanic reaction of specimens mixed with fine milled fly ash were examined. Mortar specimens mixed with three types of fine milled fly ash were cured under high-temperature condition in early ages. It was clarified that smaller particle size of the fly ash improved the early strength development of mortar. Moreover, both of finely milling fly ash particle and high-temperature curing in early ages remarkably accelerated the pozzolanic reaction of fly ash. The synergistic effect provided the acceleration of the strength development of mortar.
