“…In accordance with the 2015 Paris Agreement, global carbon emissions from the cement industry must be reduced by at least 16% by 2030 if the Earth is to remain within the pre-global warming temperatures of 1.5 • C or 2 • C [8,9]. However, with continuous urban land expansion, population growth, and economic development, statistics indicate that global cement production will increase from the current 4.08 billion tonnes to 5 billion tonnes within the next 30 years [10,11]. Furthermore, in accordance with the Global Commission on the Economy and Environment (GCEE), if developing countries increase their infrastructure to the current global average levels, then the construction industry will emit 470 gigatonnes of CO 2 into the atmosphere by 2050.…”

Eco-friendly sustainable construction materials with low carbon dioxide emissions and low energy consumption which utilize agricultural and industrial waste are widely recommended. Utilizing high-volume fly ash waste (FA) as a cement replacement will contribute to a reduction in the environmental problems related to cement production and landfill disposal. It is well known that the inclusion of high amounts of FA (up to 50%) as a cement replacement leads to low strength performance, especially at a concrete’s early age (below 7 days). In this study, a cement mortar with high-volume FA (60%) was developed with strength enhancement. With nanotechnology and nanomaterial benefits, nanoparticles from bottle glass waste (BGWNP) were produced and used to replace 2, 4, 6, 8, and 10% of cement–FA binder. The results showed that the compressive strength significantly improved with the inclusion of the BGWNP in a high-volume FA matrix and the strength trend increased from 21.3 to 328 MPa with increasing nanoparticle content from 0 to 6%. However, the results indicated that the inclusion of nanoparticles up to 6% led to a slight reduction in strength value. Similar trends were observed for other engineering and microstructure properties and the matrix containing 6% of BGWNP achieved the highest performance compared to that of the control sample. It is concluded that, with the utilization of BGWNP, there is an ability to produce high-volume FA-based cement with acceptable engineering properties as well as achieve sustainability goals by reducing pollution, recycling waste, and resolving landfill issues.

“…The same trend was observed for R 2 rubberized concrete wherein the chloride ion penetration increased from 2122 to 2916 c, and from 1640 to 2584 c, at 28 and 90 days, respectively. Moreover, type R 2 rubberized concrete showed lower chloride ion penetration, compared with type R 1 rubberized concrete in which air was easily trapped by the rough surface of the tire particles [44]. The progressive increase in chloride ion penetration with increasing rubber content may be attributed to the weak bonding between rubber particles and cement paste [57].…”

“…To reverse this situation, the present study adopted a strategy to utilize TRAs with palm oil fuel ash (POFA) to make some new types of concrete useful for structural applications. POFA has been shown to enhance the strength and durability of concrete when it replaced 20 to 30% of cement [42][43][44][45]. Additionally, reuse of various by-products from agro-industry such as POFA may minimize the hazards of disposing such materials and reduce CO 2 emissions associated with Portland cement manufacturing [46][47][48].…”

Given that rubber tires are almost immune to biological degradation, this vast amount of solid waste is a major environmental concern worldwide. Reuse of these waste tires in the construction industry is one of the strategies to minimize their environmental pollution and landfill problems, while contributing to more economical building design. Thus, we assessed the improved traits of rubberized concrete made by combining palm oil fuel ash (POFA) with tire rubber aggregates (TRAs). Studies on the effects of POFA inclusion on the durability properties of rubberized concrete with TRAs as the replacement agent for fine or coarse aggregates remain deficient. Herein, the rubberized concrete contained 20% POFA as ordinary Portland cement (OPC) substitute, and various amounts of TRAs (5, 10, 20 and 30%). The proposed mixes enclosing three types of TRAs (fiber, fine and coarse aggregates) were characterized to determine their durability and acoustic performance. The water absorption, fire endurance performance, chloride penetration, and acoustic properties of the proposed concrete were evaluated. The designed concrete showed a systematic increase in water absorption and chloride penetration with the increase in rubber amount and particle size. These POFA-modified rubberized concretes displayed a satisfactory performance up to 500 °C, and superior acoustic properties in terms of sound absorption. The presence of TRA as 30% coarse aggregate replacement was found to improve the sound absorption properties by as much as 42%.

“…From the figure 2, it was clearly observed that water absorption values were enhanced as increase the substitution level of waste rubber tyre ash in the concrete mix [42][43][44][45]. The water absorption values of sample SC100, SC95, SC90, SC85 and SC80 were 7.5, 7.7, 8, 8.3 and 8.5% at 28 days.…”

The importance of using recycled materials like rubber in construction materials is rising rapidly today. By incorporating used rubber into cement and mortar, we can save landfill space and reduce our dependence on natural resources. Rubber scrap can be mixed in as either fine or coarse aggregate. Add it to Portland cement for a stronger, more durable product (PC). This paper reviews the studies conducted so far on the feasibility of using waste rubber in place of conventional PC-based mortar and concrete’s natural fine aggregate. The strength and water-absorption capacity of materials made from ash from scrap rubber tyres were measured. Test results indicate that waste rubber ash was substitute with natural sand up 10% then strengths of the sample were enhanced after increasing the content of waste rubber tyre ash then strength was decreased. Water absorption capacity of samples was improved as increased the content of waste rubber tyre ash into concrete mix.
