Abstract
To design high-performance concrete (HPC) in a sustainable way, this paper investigates the effect of basalt fibers on the mechanical properties of HPC containing supplementary cementitious materials (SCMs), such as fly ash (FA), limestone powder (LP) and silica fume (SF). The flexural strength, compressive strength, and microstructure of the HPC are examined. The experimental results indicate that the additions of 0.1% basalt fibers in HPC shows superior mechanical properties compared to that of with 0.2%–0.3% fibers. Moreover, the HPC with 50% cement replacement by SCMs shows equivalent properties compared to the reference sample. Additionally, the pore volume of developed HPC indicates a high correlation with mechanical properties.
