Improving Mechanical Properties of Recycled Aggregate Pervious Concrete Using Taguchi Method

Abstract

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%.
