Factors Affecting Strength of Pervious Concrete with Mix Design

Pervious concrete has some properties like it is permeable and it allows the flow of water from rain and other means easily through it. The problem with normal concrete is it block the movement of water that may reduce and lower down the ground water table and also water is collected over the surface that may create problems. At that point, the concrete adhesive covers the aggregates and permits water to pass through the concrete component. Pervious concrete is customarily utilized as a part of stopping zones, regions with light movement, private boulevards, person on foot walkways, and nurseries. Porosity of any entity may increase if their voids are interconnected. In road pavement the drainage system is main concern. If water is collected over pavement then it will effect on compressive strength when it is subjected to heavy load. In this research the concrete material like course aggregate, cement and fine aggregate having specific gravity 2.68, 3.15 and 2.65 respectively. The grade of cement is taken in this research is OPC-43. The seepage quality of pervious concrete is focused and impact of compressive strength with different percentage of fine aggregate is determined in this research. The main focus is to determine the improvement in compressive and flexural strength of PCC blends and the mechanical properties of pervious concrete is also tested at different water cement ratio. An optimum percentage will be find out which shows the concrete is permeable and having good compressive and flexural strength. It is difficult to make pervious concrete with high porosity and high strength.
