- W4366498114 abstract "An experimental investigation on the hardened concrete characteristics and their association with the infiltration characteristics of pervious concrete of M20 grade prepared by utilising industrial by-products is presented. The materials used are cement as binders, copper slag as Manufactured Fine Aggregates (MFA), crushed rocks as Natural Coarse Aggregates (NCA) and manufactured fly-ash light-weight aggregates as Artificial Coarse Aggregates (ACA) along with polypropylene fibres in proportions. The influence of the size of aggregates, type of aggregates, proportioning of aggregates and addition of fibres on the engineering characteristics of the pervious concrete is observed in their relationship. The volume of fine aggregates is 5% and 10% of the total aggregate volume. The size of NCA ranges between 20 mm and 10 mm. The size of ACA is between 8 mm and 5 mm. The varying proportions of fibres added are 0.20%, 0.40%, 0.60%, 0.80%, 1.00% and 1.20% of the sum of all other materials in the concrete. M30 grade of conventional mix design is considered initially, and the objective is to reach above 60% of the strength characteristics of nominal concrete in the developed sustainable pervious concrete with sufficient infiltration capacity. The impact energy absorption capacity for the optimised mix is also adequate as per the standards. The optimum sustainable pervious concrete mix is if the design mix contains 5% MFA, 65% NCA of size between 20 mm and 10 mm and 30% ACA with 1.00% of fibres with 0.45:1 as a water-cement ratio. The optimum mix obtained is 60% above adequate strength characteristics and good infiltration capacity that pars with the M20 grade of concrete." @default.
