Abstract
This study investigated the influence of different curing methods on the strength development of municipal solid waste incinerator bottom ash alkali-activated mortars. The results showed that standard room curing is not suitable for alkali-activated materials. The main reason for this is the humidityâ¯>â¯95% in the curing room, which causes wet sample surfaces. This leads to OHâ and free alkali leaching, which severely affects strength development. Soaking curing further aggravates this effect. However, seal curing effectively prevents the leaching of OHâ and free alkali and thus maintains high alkalinity, which benefits the strength development. Therefore, the method of seal curing is more suitable for alkali-activated materials.
