PERVIOUS CONCRETE BY ADDING FLYASH MATERIAL

civil engineering

Advancements in concrete technology have resulted in the development of a new type of greener concrete, which is known as Pervious concrete. The research on pervious pavement materials has begun in developed countries such as the US and Japan since 1980s.In recent times, leader cities around the world have experienced numerous flooding due to the combination of increased rainfall and reduced in permeable surface areas. In this report we had justified the strength and permeability of Pervious concrete adding with fly ash.The OPC 53 Grade Kamal cement was used for all concrete mixes. Cement is mixed with water, sand, aggregate, and fly ash to make Pervious concrete. We made block, cylinder, and panel of pervious concrete adding with fly ash. Fly ash use in this PC is 10%,15% 20%.Size of aggregate use in this project are 12mm to 16 mm, 16mm – 20 mm. After performing the compressive strength test on cubes of course aggregate and cubes of rounded aggregate, we gained the strength of cubes in which coarse aggregates are used is less than the cubes in which rounded aggregates are used. Field sites for existing pervious concrete were located in our collage DJMIT. It is hoped that by developing more standardized installation method and documentation concrete pervious block strength can be achieved.
