Being at the core of construction pervious concrete has gravitate curiosity of many passionate researchers towards itself. They studied and experimented with different composition to evaluate efficiency of pervious concrete. Such explorations lead to conquering many hurdles and lead ultimately to sustainable development, a very important aspect of research in the 21st century. The main objective of the work is to investigate the experimental investigation of pervious concrete with special admixture fly ash and super plasticizer permaplast. In this work, a brief literature review has been carried out on previous concrete, fly ash and permaplast. The size of the cubes 150 mm were used to assess the compressive strength of porous concrete. The percentage of Fly ash is varying like 5%, 10%, 15%, 20% was used in this study for replacement of cement. From this comparison of different flyash percentage will make the economic as well as the strength benefits. The pervious concrete are also eco-friendly for the ground water recharge activities. From this cost analysis we can conclude that 5% of fly ash saves the cost of 71 rupees when compared with 100% of cement and also the strength of the pervious concrete mix with fly ash and permaplast nearly attain to the pervious concrete but not get increased.
