The construction demolishing is non-degradable. Recycled aggregates were utilized to create sustainable products in pervious concrete manufacture. Adding fiber enhances pervious concrete mechanical properties. High absorption of RA and polyethylene-glycol are used to ensure internal curing. The purpose of this study was to statistically improve mechanical properties of pervious concrete using an experimental investigation. Taguchi method was employed to present DOE (Design of Experiment). Five factors in four levels designed by Taguchi provide sixteen mixes (L16 array). The factors were replacement of coarse aggregates by recycle aggregates, W/C ratio, synthetic macro-fiber, steel fiber and polyethylene-glycol.Designed mixes were prepared. Taguchi analysis concluded; macro-fiber addition has no impact on mechanical properties. 10% recycle aggregates replacement was the optimum ratio. Taguchi analysis allowed prediction of non-experimented results and evaluating mechanical properties values. Prediction of optimum mixes were experimented though confirmation mixes. Confirmation test results were the predicted values within ±10%.

“…The water-to-cement ratio (W/C) was consistently set to 0.45. The process of preparing the samples for estimating the hardened characteristics of WFN fiber-reinforced concrete was conducted as follows: The plain concrete mixes were prepared with a concrete mixer based on a normal process [ 18 , 26 ]. The slump tests were conducted to ensure consistency in the workability characteristics for all the plain batches before the specified amounts of WFN fibers were added [ 37 ].…”

“…The effectiveness of R-PET fibers in reducing the cost of the material while achieving good energy absorption capacity in cementitious composites can be found in [ 25 ]. In addition, the study of Tran et al [ 26 ] dealt with the performance of pervious concrete containing fibers obtained from recycled plastic bags. Their observations showed an improvement in the microparticle filtration capacity while both the compressive and flexural strengths of the composite materials were reduced.…”

In this study, we estimate the potential efficiency of waste fishing net (WFN) fibers as concrete reinforcements. Three WFN fiber concentrations (1, 2, and 3% by volume) were mixed with concrete. Compressive strength, toughness, splitting tensile strength, and biaxial flexural tests were conducted. Compressive strength decreased but other properties increased as a function of fiber proportions. According to the mechanical strength observations and the ductility number, WFN fibers yielded benefits in crack arresting that improved the postcracking behavior and transformed concrete from a brittle into a quasi-brittle material. It is inferred that WFN fiber is a recycled and eco-friendly material that can be utilized as potential concrete reinforcement.

In order to improve the comprehensive performance of pervious concrete, nano-silicon and polypropylene fiber were added to pervious concrete to study the change of performance of pervious concrete. Firstly, the effect of single doped nano-silicon on the properties of cement slurry and pervious concrete was studied, and the optimal water-binder ratio and nano-silicon content were determined. Based on this, mixed polypropylene fiber with different proportions of length of 18 mm to determine the reasonable amount of polypropylene fiber. The results showed that the compressive strength of pervious concrete was the highest when the nano-silicon content was 0.5% and the water-binder ratio was 0.32. Based on this ratio, the maximum compressive strength can be obtained by adding 1.0 kg/m3 polypropylene fiber, and the compressive strength of 7d and 28d increased by 29.9% and 42.2%, respectively. Adding 1.5 kg/m3 polypropylene fiber was the most beneficial to improve the freezing resistance of pervious concrete. For example, after 300 freeze–thaw cycles, the compressive strength residual rate was 62%. That's much higher than the 40 percent that was found when nano silicon was mixed alone.
