Researchers have continuously attempted to reduce and recycle construction waste. Ceramic waste is mainly a byproduct of the manufacturing process. About 25% of the waste is produced because of dimension defects or incurring problems throughout the industrial process. This article aims to highlight the alternative uses of ceramic waste. In this research, ceramic waste at a powder status is reduced to fine aggregates. Here, ceramic waste powder (CWP) is used in different ratios of 25%, 50%, 75%, and 100% replacing the fine aggregate weight. Aluminum powder is used to obtain aerated concrete (AC). Glass fibers are added in ratios of 1%, 1.5%, and 2% of cement weight to obtain a fiber‐reinforced AC. The unit weight, compressive strength, splitting tensile strength, and thermal conductivity are estimated. Furthermore, scanning electron microscopy is performed to investigate the microstructure features of the composite. The results exhibit better performance in compressive and splitting tensile strength when fine aggregates were replaced by 25% and 50% of CWP. In addition, 1.5% of GFs enhance the compressive and splitting tensile strength. In addition, increasing the CWP decreases the unit weight of fiber‐reinforced AC. It is shown that CWP strongly influences the thermal conductivity of the fiber‐reinforced AC, resulting in a high composite resistant to heat transmission. The technique for order preference by similarity to an ideal solution method is used to obtain the optimal mix.

“…Li et al [7] reported that polypropylene fiber effectively reinforced the LWAC and improved its tensile strength, flexural toughness, and impact resistance; moreover, an optimal polypropylene fiber content of 9 kg/m 3 was recommended. Although a single fiber improves the properties of concrete at only a single scale, it was reported that concrete reinforced with two or more different types of fiber can benefit from each individual type of fiber and generate a positive synergistic response [8]. For hybrid fiber-reinforced concrete, dispersed fibers can effectively restrain the formation and propagation of cracks through a bridging effect at both the macro and micro levels, leading to an increase in the tensile behavior and toughness [9].…”

The impact of carbon and polypropylene fibers in both single and hybrid forms on the properties of lightweight aggregate concrete (LWAC), including the slump, density, segregation resistance, compressive strength, splitting tensile strength, flexural strength, and compressive stress–strain behavior, were experimentally investigated. The toughness ratio and ductility index were introduced for quantitatively evaluating the energy-absorbing capacity and post-peak ductility. A positive synergistic effect of hybrid carbon and polypropylene fibers was obtained in terms of higher tensile strength, toughness, and ductility. The toughness ratio and ductility index of hybrid fiber-reinforced LWAC were increased by 26%–37% and 12%–27% compared with plain LWAC, respectively. The fiber in both single and hybrid forms had a smaller effect on the linearity ascending branch of the stress–strain curves, whereas the post-peak patterns in terms of the toughness and ductility for the hybrid fiber-reinforced LWAC were significantly improved when the fiber in hybrid form.

“…In order to modify the properties of concrete, the polypropylene fiber (PPF) could be added [17][18][19][20][21][22][23][24][25][26][27][28], and the PPF was found to be very effective in improving the crack resistance compared to other methods. The addition of PPF was found to decrease the workability [17] and increase the compressive strength [29][30][31][32], crack resistance [33][34][35], and durability [31,[36][37][38][39][40][41] given that the PPF was within an optimum content.…”

With the depletion and increasing demand of river sand, machine-made sand could be used more and more in concrete. In order to improve the properties of machine-made sand concrete, the effects of the aggregate micro fines (AMF) content, aluminum sulfate, and polypropylene fibers (PPF) on the slump, compressive strength, water permeability, and the chloride permeability coefficients were investigated through a single factor test method, and related mechanisms were analyzed. The results show that the optimum contents of AMF, aluminum sulfate, and the polypropylene fiber are 10 wt%, 1 wt%, and 0.6 kg/m3, respectively. The optimum content of AMF improved the compactness of concrete. The addition of aluminum sulfate promoted the initial formation of ettringite, and thereby improved the compressive strength and the permeability resistance. The polypropylene fiber can modify the pore structure distribution of concrete and reduce the porosity, thereby improving the impermeability of the concrete. The compressive strength of the machine-made sand concrete could be increased by more than 20%, and the water/chloride permeability coefficients could be decreased by more than 45%.
