文摘
- •
The surface treatment by presoaking the recycled aggregates in acids significantly improves the properties of RA.
- •
Acid treated and silica fume impregnated recycled aggregate gave better concrete strength in the later age.
- •
The strength development of recycled aggregate concrete with treated RA was better than untreated RA.
