Predictive modeling for sustainable high-performance concrete from industrial wastes: A comparison and optimization of models using ensemble learners

Basalt fibers (BFs) have attracted much attention in the composites industry because they are chemically stable and have excellent mechanical and thermal properties. Due to their high commercial value, BFs have many applications in the polymer and construction industries. Although BF dosage is a key factor in basalt-fiber-reinforced composites (BFRCs), and mechanical performance improves significantly as the dosage increases, the fiber–matrix interface is another important parameter that determines the performance of BFRCs during their service life. The adhesion between the matrix and the BF is crucial for transferring stress and enhancing the mechanical properties of the composite. This paper reviews polymer and cement composites reinforced with BF and discusses strategies for improving the fiber–matrix interface, such as surface modification of the fibers and the addition of micro- and nanofillers to the matrix.

This study investigated the influence of ultrafine fly ash (FA) on the mechanical properties, elevated temperature resistance and water stability of basalt fiber reinforced magnesium phosphate cement, and synergy mechanism was examined with the help of X-ray diffraction (XRD), thermogravimetric analysis (TGA), mercury intrusion porosimeter (MIP) and scanning electron microscopy energy dispersive spectroscopy (SEM/SEM-EDS) analysis techniques. Experimental results showed that incorporation of FA improved the mechanical properties, temperature resistance and water stability of MPC composites. TGA results exhibited that the mass loss of MPC composites was gradually reduced by increasing the percentage of FA. MIP analysis showed that cumulative pore volume, volume percentage of large pores and mean pore diameter of were decreased with the addition of FA. XRD and SEM-EDS analysis of MPC composites revealed the formation of secondary reaction products, that could be possibly responsible for the superior properties of FA/MPC composites. Importantly, the results of all characterization techniques corroborated with the mechanical results of MPC composites.
