This study evaluates the feasibility of paper ash (PA) as a partial cement replacement (0%, 5%, 10%, and 15% ) with a constant 15% stone powder (SP) as a sand replacement. Fresh and hardened properties were assessed through slump, compressive strength, and split-cylinder tensile tests. Furthermore, the microstructura...

ABSTRACT Basalt Fiber Reinforced Concrete (BFRC) is being recognized as an eco-friendly advanced material with reduced environmental footprint, higher mechanical performance and long-term durability. However, its compressive strength prediction still appears to be a difficult problem due to the nonlinearity caused by t...
