Abstract The current study aimed to investigate the influence of expired hardened cement blended with ground granulated blast furnace slag on bond, microstructure, and durability high-strength concrete (HSC). Five mixes are prepared; first mix is taken as a control, remaining four used experimental blends. HSC characteristics evaluated by compressive, flexural, splitting tensile, tests. Further...

The present study focused on developing Alkali Activated Fine Aggregate (AAFA) by palletization method. AAFA was manufactured using Ground Granulated Blast Furnace Slag (GGBS) and alkali activator solution at ambient conditions. Sodium hydroxide of six molarity sodium silicate to ratio 2.5 used. AACA's properties are similar Natural except for flakiness elongation index. water absorption Abrasi...
