TLDR
In this paper, the effects of nano-silica incorporation on an eco-friendly alkali activated slag-fly ash blends were investigated, and the results indicated that as the nano silica content increases, the slump flow is significantly reduced, and reaction process is slightly retarded according to the setting time and isothermal calorimetry results.About:
