Effect on the Engineering Properties of Pervious Concrete by Partial Replacement of Cement with GGBS
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 3
Abstract
Pervious concrete which is also known as the no-fines, porous, gap-graded, and permeable concrete and enhance porosity concrete has been found to be a reliable storm water management tool. By definition, pervious concrete is a mixture of gravel or granite stone, cement, water, little to no sand (fine aggregate) with or without admixtures. Pervious concrete is traditionally used in Parking areas, areas with high traffic, walk ways in parks and gardens, Residential streets, Pedestrian walkways and Green houses, Basketball and volley ball courts etc. In this study experimental investigation is carried out to study the properties of Pervious Concrete by partial replacing cement with different percentages of GGBS (0%, 20%, 40%, 50%, 60%, and 80%). To achieve optimum concrete mix various trial mixes are done by varying cement, coarse aggregate, water and super plasticizers. Once getting the optimum mix, six mix design are done by replacing cement with GGBS at 0%, 20%, 40%, 50%, 60%, 80 %. The pervious concrete mix is produced by using conventional cementitious materials, aggregates, and water. This concrete is tested for its Fresh properties such as workability and Hardened Properties such as density, void ratio, compressive strength, and water permeability. The most important property of pervious concrete is its water permeability. Currently, there is no standard experimental procedure to determine to this property. A method was therefore developed to determine the water permeability.
