Pervious concrete should be chosen for its obvious environmental benefits. As environment is concerned, carbon dioxide emission from Portland cement production is significant. Therefore, by partially replacing the cement with industrial by-product, such as fly ash and slag which have been used successfully as supplementary cementitious materials. The change in properties of pervious concrete due to size of aggregates used is being assessed in this project. The concrete is assessed for its Compressive Strength, Split Tensile Strength, Permeability and flexural strength. The results are interpreted based on graphs obtained. KEYWORDS: Pervious concrete, Flyash, GGBS, falling head permeability. I. INTRODUCTION Pervious concrete is considered a sustainable building alternative for concrete and/or asphalt pavement parking lots because it provides pollution mitigation and storm water management. Pervious concrete acts as a filtration device for storm water and turns the entire parking area, pathway, or other paved surface into a retention treatment basin.Storm water can flow through the pavement to the subgrade underneath, taking with it pollutants that would typically end up in municipal storm water systems. Naturally occurring soil microbes then store and break down the pollutants, preventing aquifer pollution. Advantages of Pervious Concrete  The benefits of pervious concrete are not limited to its infiltration capacities.  A number of studies have shown its potential to remove pollutants from water,  Decreasing flooding possibilities, especially in urban areas and reducing puddles on the road  Reduce noise, improve skid resistance, and  Help mitigate the heat island effect  It returns rain water to the ground, recharging ground water and aquifers  The runoff from paved areas is reduced, which reduces the need for separate storm water retention  Supporting vegetation growth II. RESEARCH SIGNIFICANCE Evaluating the performance of pervious concrete using locally available aggregates is important for use in local regions. Moreover using supplementary cementitious material changes the properties of concrete mix which may lead to variation in strength properties as well as the porous structure of the concrete hence it has to be assessed.
