Effect of Curing Temperature on Pozzolanic Reaction of Fly Ash in Blended Cement Paste

Mongkhon Narmluk and Toyoharu Nawa
Abstract—In this research, the degree of pozzolanic reaction of fly ash in blended Portland cement pastes cured at different temperatures was determined by the selective dissolution method. The effect of curing temperature on pozzolanic reaction was then investigated using the modified Jander’s model. The results confirm that the pozzolanic reaction of fly ash is strongly influenced by curing temperature and replacement ratio of fly ash. The higher the curing temperature and the lower the fly ash replacement ratio, the higher is the degree of pozzolanic reaction of fly ash. The rate and mechanism of pozzolanic reaction of fly ash vary with curing temperature. Elevated curing temperatures lead to faster the onset and accelerated the rate of the main reaction linearly.

Index Terms—Fly ash, pozzolanic reaction, cement paste, curing temperature, hydration.
