“…The water absorption value is mainly influenced by various factors including the type of cement, the curing standards, and the surrounding environment [37,38]. The content of water absorption is very low in these epoxy mortars because the epoxy resin is a waterproofing material [16]. Water absorption in epoxy PVC (EP) waste mortar was greater than that in epoxy resin because due to the existence of pores in the epoxy PVC mortar.…”

“…The epoxy mortar's mechanical strength increased as the epoxy resin content increased. By taking samples of a composition of 20% fly ash (FA) and 80% ground coal burning ash (GCBA), it was observed that the mechanical strength increased from 32 MPa to 38 MPa, but it decreased as the as the epoxy resin content increased from 10% to 30% [16].…”

“…A thorough examination revealed that research had been conducted on the impacts of using steel slag, marble dust, and PVC waste along with natural sand as a filler in epoxy mortar [17][18][19]21]. Due to their widespread availability and compatibility with building materials, these wastes could be utilized as filler in place of sand in epoxy composites [16]. The epoxy resin depends on the constituents of the mortar.…”

This paper presents experimental investigations on epoxy mortar produced using industrial wastes. In some recent studies, coal bottom ash and polyethylene terephthalate (PET) waste have been chosen as a filler to replace sand, and fly ash and silica fume have been chosen as micro fillers for epoxy mortar production; enhanced results in terms of compressive and tensile strengths and durability have been achieved. However, these approaches failed to boost the strength and durability compared to the epoxy steel slag, epoxy sand, epoxy marble dust, and epoxy polyvinyl chloride (PVC) waste. This present research work has investigated the influence of waste filler on the mechanical properties and microstructure of epoxy mortar, produced by using sand and industrial wastes, i.e., steel slag, marble dust, and polyvinyl chloride waste. Based on the composition ratio, the prepared samples of epoxy resin mortar containing 25% epoxy binder (epoxy resin plus epoxy hardener) and 75% filler (1:3) were compared to the cement mortar. However, each specimen of epoxy resin mortar was prepared by mixing with different fillers. The properties such as compressive strength, tensile strength, and microstructural changes were measured using different characterization techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared radiation spectroscopy (FTIR), and scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDX). From the obtained results, it was found that the strength of the specimens increases when blended with steel slag and marble dust, which is attributed to their peak densities and enhanced particle interactions. The XRD, SEM, FTIR, and SEM-EDX analyses showed the formation of calcium, magnesium, and other phases in the microstructure of epoxy resin-based mortars. This resulted in lower water absorption and porosity, as well as improvements in both compressive and tensile strengths. This research can help in understanding the important role of different industrial wastes as feasible fillers in epoxy resin-based composites.

“…Furthermore, the production of railway sleepers, which are essential components of railway infrastructure, benefits in terms of increased durability and longevity owing to the use of epoxy materials. The widespread adoption of epoxy composites faces a significant barrier due to the high costs associated with epoxy resins, particularly when compared to conventional Portland cement [6,7]. This cost disparity can be attributed to several factors, including the intricate manufacturing processes involved in producing high-quality epoxy resins and the raw materials required for their formulation.…”

This article explores the use of olive pit powder (OPP) as a promising resource for enhancing the thermal insulation properties of epoxy mortars. A comprehensive analysis of the chemical and physical characteristics of OPP was conducted, employing analytical techniques including scanning electron microscopy (SEM), thermogravimetric analysis and emitted gas analysis (TG-MS-EGA), and proximal analysis. Experimental samples of epoxy grout were prepared by using different proportions of a conventional inorganic filler, quartz powder, and OPP within an epoxy mortar matrix. As the percentage of OPP in the formulation increased, the microstructure of the samples gradually became more porous and less compact. Consequently, there was a decrease in density with the increase in OPP content. The 28-day compressive strength decreased from 46 MPa to 12.8 MPa, respectively, in the samples containing only quartz (Sample E) and only OPP (Sample A) as a filler. Similarly, flexural strength decreased from 35.2 to 5.3 MPa. The thermal conductivity decreased from 0.3 W/mK in Sample E to 0.11 in Sample A. Therefore, increasing the %wt of OPP improved insulating properties while reducing the mechanical resistance values. This study highlights the potential of OPP as an environmentally friendly and thermally efficient filler for epoxy mortars, thereby promoting sustainable construction practices.

“…farm incineration, burial, or disposal in landfills) have caused serious environmental issues and prompted great interest in clean energy recycling method [5]. The adoption of waste as green construction materials has been a popular research approach due to increased awareness of sustainable development [6]. It is a plausible effort to incorporate waste newspaper ash as a supplementary cementing material for producing concrete.…”
