- •
Increasing finer LP up to 10 wt% improves workability of coarse tailings CPB.
- •
Coupled effects of LP and WRA are outstanding beneficial to workability of CPB.
- •
The complex incorporation of LP and WRA benefits mechanical performance of CPB.
- •
The UCS of CPB becomes larger when the pores of CPB samples becomes finer.
