This study investigates the chloride penetration resistance of fine recycled aggregate concrete (FRAC). Six mixes comprising 0.45 and 0.55 w/b were prepared using aggregates (FRA) at 0, 25 50% by volume replacement natural sand. The was tested surface electrical resistivity (SER), conductivity index (CCI), bulk diffusion tests. SER CCI tests conducted after 28 days 180 wet curing, while test ca...

The effective use of construction waste is great significance to the a sustainable society. This study investigated permeability recycled aggregate concrete with different qualities. aggregates were treated crystallizing agent. improvement effect crystallization was evaluated by rapid chloride ion migration test and electron microscope observation. results show that calcium silicate hydrate gen...
