Experimental study on pervious concrete as a drain cover slab

Abstract

The experimental study on the pervious concrete as a drain cover slab influence the use of cement, fine aggregate, coarse aggregate, steel fibers & fly ash to form porous concrete. The objective of the study is to find out the best pervious concrete slab composition with good strength and infiltration rate. This objective is achieved by an experimental study on properties, behavior, permeability, and durability on four different mix samples and two different mix type slabs are compared to conventional pervious concrete. Materials used for the Mix are OPC-53grade, Fine aggregate with grade II of river sand and Material sand, Coarse aggregate of 12.5mm-20mm, crimped steel fibers, plasticizer as Dew-bond P99 with 1:4.75 cement to Coarse aggregate ratio. The mix of M1, M2 M3, and M4 are prepared with the W/C ratio of 0.34 with water reducing admixture. The mix is compared with each other on strength, permeability. Based on the results the Slab mix is selected and studied as slab specimen for their strength, infiltration. The test is carried out based on the Indian standards and ASTM for permeability test.The results obtained show sustainable and good strength pervious concrete slab.
