文摘
- •
Fresh properties of self-compacting lightweight concrete (SCLC) is investigated.
- •
Lightweight aggregates (LWAs) made from 90% fly ash and 10% cement by pelletizing.
- •
Treated LWA and nano-silica (nS) contributed to a higher blocking ratio.
- •
Higher viscosity was accompanied the higher amount of nS addition.
- •
Treated LWAs improved SCLC workability and 28 days compressive strength.
