Engineering of green cementitious composites modified with siliceous fly ash: Understanding the importance of curing conditions

Siliceous fly ash can be applied as a cement replacement material for mortars used in cement-based floor overlays. At present, there is no knowledge of the appropriate curing conditions that need to on concrete floors. Moreover, previous research related has left gaps which such floors are cured. This study focuses understanding importance typical overlays physical, chemical, mechanical, and microstructural properties siliceous ash-modified mortars. The results indicate have significant impact these (particularly long-term effects). Differences were observed between cured different conditions. In this research, we investigated volume porosity, water absorption, microstructure, hydration process, pore segmentation, strength composites had partially replaced with addition ash. It should noted use properly could lead better green cementitious composites.
