Urbanization and industrialization go hand in hand affecting the change in lifestyle of an individual. Demolition of old and non-economical structures and construction of new is the basic cycle humans are following.  This is affecting the environment at an adverse rate due to wastage of recyclable materials and production of new raw materials. The construction industry is one of the key producers of non-recyclable waste so it is our duty to find ways and methods to use the demolished waste from the construction industry and convert it into a usable form. Demolished concrete is one of the key ingredients of this waste industry but with some mechanical procedures and alterations, this can be converted into a usable form sufficient to be used in the construction process. This paper provides an overview of the mechanical process used for converting the demolished concrete into usable concrete and admixtures used for making this concrete more efficient.
