    I want to prepare a list of new waste materials
    it's so important if anyone introduces new ones that I can use in some construction concrete.
    Thank you

    I don't think you should add some waste in concrete structure because it will decrease its strength. It is better you add waste plastic in bituminous road.

    Dear Zaheer, it is curious, but we are adding shredded PET and PVC in our lab, and we improve other properties rather than compressive strength. It changes material toughness and permeability. At the same time, the compressive strength is not severely reduced if you use the proper amount of waste material. Also, demolish materials are also considered as waste... you can use them as coarse aggregate and improve the carbon footprint of the infrastructure. Those are some areas that we have to continue investigating.

    Hi Mr. Sina Lotfollahi,

    Are you referring to recyclable materials? Unfortunately, I know more about english than any other language, so I am not familiar with the text shared on the website. But there are recycleable materials such as glass, plastic, cans, and vehicle tires that have been reused to create walls in combination with concrete. You can find more under searches like "tiny homes recycled material" "earthship" and "recycled tire constructions". You will find many architecture students and professionals researching these topics too. Enjoy! 

    List of homes made from recycled tires called earthship:

    Glass fillers:

    Many people use recycled material, artists also do this for their art pieces.
