The main objective of this investigation is to increase the strength of pervious concrete by producing
various mix design. In pervious concrete fine aggregate is not normally used but our aim is to use some percentage of
sand and chemical composition to improve the strength of pervious concrete. To further improve the strength of
pervious concrete addition of cementations material such as fly ash. The main properties studied are compressive
strength, permeability and flexural strength. The falling head test method was used to find out permeability coefficient. After various combinations fine aggregate size pervious concrete produced with mix size aggregate having
more compressive strength than single size of aggregate.
