“…Nonetheless, it has been demonstrated that the presence of unreacted FA particles in the FOC matrix aids in matrix densification and minimizes the formation of microcracks. This behavior is consistent with other studies demonstrating that the ability of unreacted FA particles to densify the Ms of GP concrete improves strength performance [ 96 , 98 , 249 , 250 ].…”

Geopolymer (GP) concrete is a novel construction material that can be used in place of traditional Portland cement (PC) concrete to reduce greenhouse gas emissions and effectively manage industrial waste. Fly ash (FA) has long been utilized as a key constituent in GPs, and GP technology provides an environmentally benign alternative to FA utilization. As a result, a thorough examination of GP concrete manufactured using FA as a precursor (FA-GP concrete) and employed as a replacement for conventional concrete has become crucial. According to the findings of current investigations, FA-GP concrete has equal or superior mechanical and physical characteristics compared to PC concrete. This article reviews the clean production, mix design, compressive strength (CS), and microstructure (Ms) analyses of the FA-GP concrete to collect and publish the most recent information and data on FA-GP concrete. In addition, this paper shall attempt to develop a comprehensive database based on the previous research study that expounds on the impact of substantial aspects such as physio-chemical characteristics of precursors, mixes, curing, additives, and chemical activation on the CS of FA-GP concrete. The purpose of this work is to give viewers a greater knowledge of the consequences and uses of using FA as a precursor to making effective GP concrete.

“…The addition of ceramic tile aggregates may slightly increase the flexural strength of concrete, according to Zareei et al [27] and Bommisetty et al [85] (Fig. 21a); however, ceramic tile aggregates had a negative impact on the strength of concrete and a higher ceramic tile content corresponded to a lower flexural strength according to Rajprasad et al [23] and Mohammed et al [107] (Fig. 21b).…”

Green and sustainable concrete has attracted significant attention from the construction industry and researchers since it was proposed. The ceramic waste materials are often directly buried in the ground or placed in an open dump, and the accumulation of ceramic waste contributes to environmental pollution, which makes the recycling of ceramic waste quite urgent. Owing to the pozzolanic activity, excellent mechanical properties and durability, industrial ceramic waste is considered as a suitable substitute for cement or natural aggregates to fabricate renewable concrete. In this paper, the pozzolanic activity of ceramic waste and the workability, mechanical performance, and durability of ceramic concrete are discussed. In addition, the most recent research results pertaining to ceramic concrete are reviewed. Ground ceramic powder improves the workability, compressive strength, resistance to chloride penetration, and carbonation resistance of concrete to a certain extent. Concrete containing ceramic as the aggregate has a lower mechanical performance than ordinary concrete. However, the resistance to chloride penetration, freeze-thaw resistance, and high-temperature resistance of ceramic concrete are remarkable. Ceramic concrete is environmentally friendly, requires fewer energy resources to manufacture than ordinary concrete, and has excellent engineering properties. However, further research is required for future engineering applications.

“…It was attributed to stronger hydrogen bonding by the hydrophilic PVA fiber, which led to superior resistance to crack propagation and microcracking. It has been observed in the literature that there are existing experimental works to predict the behaviour of ceramic concrete or hybrid fiber concrete [15][16][17][18][19][20][21][22][23][24] . However, there is no available experimental work to evaluate the effect of adding Hooked end steel fiber (HK) +polyvinyl alcohol (PVA) or Crimped steel fiber (CR) + polyvinyl alcohol (PVA) with waste ceramic materials on the mechanical properties of concrete, as well as find out the optimal hybridisation of Hooked end steel fiber (HK) +polyvinyl alcohol (PVA) or Crimped steel fiber (CR) + polyvinyl alcohol (PVA), which is important to investigate under different loadings (Compressive, tensile, flexural and torsion); this study can be used to be a reference for future studies and provide extensive data for hybridisation of fibers with ceramic materials studies.…”

Combining different types of fibers inside a concrete mixture was revealed to improve the strength properties of cementitious matrices by monitoring crack initiation and propagation. The contribution of hybrid fibers needs to be thoroughly investigated, considering various parameters such as fibers type and content. The present study aims to carry out some mechanical and microstructural characteristics of Waste Ceramic Optimal Concrete (WOC) reinforced by hybrid fibers. Reinforcement materials consist of three different fiber types: hook-ended steel fiber (HK), crimped steel fiber (CR) and polyvinyl alcohol (PVA) fibers and the effect of their addition on the waste ceramic compositesâ€™Â mechanical behaviour. Furthermore, a microstructural analysis was carried out to understand the waste ceramic matrix composition and its bonding to hybrid fibers. Results showed that the addition of hybrid fibers improved the strength characteristics of the ceramic waste composites. For instance, the existence of PVA-CR increased the tensile and flexural strength of the waste ceramic composite by 85.44% and 70.37%, respectively, with respect to the control sample (WOC). As well as hybrid fiber exhibits improved morphological properties as a result of increased pore filling with dense and compact structure, as well as increased Câ€“H crystals and denser structure in pastes as a result of the incorporation of hybrid fibers into the concrete mix. The present experimental research shows the choice of using steel fiber with PVA as a reinforcement material. The idea of adding hybrid fiber is to prepare the economic, environmental, and technological concrete. Moreover, it offers a possibility for improving concreteâ€™s durability, which is vital. Finally, itÂ was concluded that steel fiber is more durable, and stiffer and provides adequate first crack strength and ultimate strength. In contrast, the PVA fiber is relatively flexible and improves the post-crack zoneâ€™s toughness and strain capacity.
