This paper presents the results from the numerical and experimental evaluation of the effect of various parameters on the properties of basalt fiber-reinforced cementitious composites (BCCs). The parameters considered in this study are the fly ash-portland cement content ratio, sand-binder ratio, water-binder ratio, and dosage of basalt fibers. The mixtures investigated were designed using the Taguchi method, and the corresponding compressive strength and permeability properties were investigated. Findings from this study
show that the use of basalt fiber at a dosage of 2% is optimum
to achieve good strength and permeability properties. Optimized results also show a good correlation with experimental results. The optimized composite with compressive strength, sorption, and porosity of 26.1 MPa, 0.4 mm, and 4.81%, respectively, experimentally yielded a corresponding 24.6 MPa, 0.32 mm, and 4.03% for compressive strength, sorption, and porosity, respectively.
