“…All in all, cement, W, CA, SF, GF, and the age of samples were selected as input variables. 1 Eventually, 12 (single and hybrid) different regression techniques have been used to predict the CS of RAC, in which input variables are: B, W/B, CA/TA, CA/B, SF/B, GF/B, and AC. The performance of the developed models was then compared with the performance of the experimentally determined amounts.…”

Reuse and recycling of construction wastes effectively prevent further destruction of the environment and nature due to the construction industry. One of the conventional methods is the reapplication of recycled aggregates (RAs) in concrete mix design and construction. Compressive strength (CS) is a considerable representation of the mechanical properties of recycled aggregate concrete (RAC). The present study is divided into two parts of experimental and predicting. In the laboratory studies phase, RA was used with 100% replacement. Due to the proven defects in RAC, glass fibers and silica fume (variables) have been used to compensate for these defects. Different mixing designs were used to construct concrete samples, and then the CS of each specimen was measured in the laboratory. Afterward, these data were used as training and testing in various conventional, ensembled and hybrid models as the tree-based learning algorithms, rules, Lazy-learning Algorithms, Functions, and Meta classifiers. Considering the applied performance statistical criteria (R 2 , root mean squared error, mean absolute error, and mean absolute percentage error), all models have provided excellent and acceptable results, which the precision of the multilayer perceptron single model and additive regression-random Forest hybrid model have the best agreement with measured values of CS of RAC.

“…The previous study reported that ductility was improved by adding fibres and that tensile strength increased in two types of SF added to concrete, as shown in Figure-17 [184]. Similarly, tensile strength and ductility were shown to increase by raising the WPF content, due to greater ultimate applied load and decreased internal stresses, [167]. Moreover, tensile strength was found to increase with SF and RAC without fibres by 9-16.6%.…”

“…As noted, compressive strength decreases as the proportion of fibres increases in the concrete [28]. Moreover, compressive strength was found to be reduced with an increase in WPF values because the fibre lowered the workability of the mix, which grew porous [167]. However, other researchers reported that the addition of silica fume to steel fibre RAC (SRAC) after exposure to high temperature achieved significantly improved compressive strength, toughness and elastic modulus [10,168].A slight effect on compressive strength was reported after adding two types of SF [108].…”

“…Polyethylene terephthalate (PET) belongs to polyester family and is a thermoplastic polymer that is commonly used in water bottles. The literature reveals that PET establishes the most common plastic waste in the plastic family which might be due to the difficulty related to recycling of these products as well as its high production rate [123]. The inclusion of PET in concrete has been shown to reduce slump, and increase the impact and cracking resistance [118].…”

Due to constant growth of waste production, recent strategies in waste management such as circular economy promote the maximum life cycle use of materials. In construction industry where structures tend to last for decades, the use of such recycled materials can have numerous benefits including overall reduction in cost, in use of virgin materials, and in CO2 production as well as providing an opportunity for a tailored concrete with specific properties. Yet, because of the stereotypical and negative image of mechanical properties reduction, as a result of using waste materials, often their vast contribution in sustainability and durability properties are not taken into consideration. In this regard, we propose viewing waste materials as secondary raw materials that in certain regards, can provide a favorably tailored property. In this regard, the following review article first provides a short description of the most commonly used waste materials such as supplementary cementitious materials (fly ash, ground granulated blast furnace slag, silica fume, metakaolin, rice husk ash, municipal solid waste ash, steel slag, copper slag), ceramics from construction and demolition (glass powder, brick and tile ceramic and porcelain), and the vastly available plastic materials (polypropylene, polyethylene terephthalate, polyvinyl chloride, and rubber). Then, by reviewing a selected environmental impact (life cycle assessment), physicochemical, durability, and finally mechanical properties discuss the limitations, future projections of newer waste materials (e.g., agricultural waste) to be used and suggest potential future study in this area.
