Contribution of fly ash to the strength development of mortars cured at different temperatures

摘要

This study aims to determine the contribution of fly ash to the compressive strength development of mortars cured at different temperatures based on the cementing efficiency factor. The strength development of mortar specimens with different fly ash replacement ratios cured at 10 degrees C, 20 degrees C, and 30 degrees C was analyzed considering the apparent activation energy. Subsequently, the contribution of fly ash was assessed using the cementing efficiency factor. The results indicate that the cementing efficiency factor is significantly affected by the curing temperature and can be estimated using the cumulative temperature and the appropriate datum temperature for fly ash cement.
