ABSTRACT

Conventional cement concrete is commonly used for pavement construction; this pavement has an impermeable character, which increases runoff into the drainage system, causing overburdening of the drainage system and water stagnation in built-up regions. Pervious concrete is a form of concrete with a high porosity that is used for concrete pavement and allows storm water to flow from the surface to the bottom of the pavement. As a result, drainage from a location is reduced, enabling groundwater recharge. Glass fibers have the potential to be a useful material for improving the characteristics of pervious concrete. It is an excellent replacement material for cement, and as a result, the strength of the mix will improve. Glass fiber is employed as a partial substitute for cement in this study. Additionally, as we are utilizing 10% fly ash as a substitute for cement in the absence of fine aggregate. This study examines the impacts of glass fibers and fly ash on ordinary pervious concrete pavement, as well as the use of M sand in percentages of 5%, 10%, 15%, and 20% in terms of fine aggregate. To investigate the impact of glass fibers, fly ash, and M sand on the characteristics of porous concrete, compressive strength, split tensile and flexural tests, and permeability tests will be performed.
