Mechanical Behaviour of Concrete by using Waste Plastics

Rapid urbanization and industrialization cause a lot of infrastructure development is taking place in the last two decades. Due to this process, it leads a big problem. There are so many shortages of construction materials, increasing of wastes and other products. All the waste products have to be recycled in order to create a balance between production and disposal of wastes. The other alternative uses found are to use waste plastics in the Construction Industry. In this project we used the waste plastics in Cement Concrete construction. Standard Mix ratio for framed and unframed structure is M20, since it gives maximum strength to the structure to bear the Loads. Plastics are used in various ways for our project used as modifier. Plastics are added in the percentage of 2%, 4%, 6%, etc…, for the replacement of cement and sand. Many tests were conducted for the materials and determine their physical and mechanical properties. From those results Experimental investigations comprised of testing for physical requirements of Course Aggregates (CA), Fine Aggregates (FA), cement and the modifier. From that result the replacement content was 6% and the strength was found to be twice than plain cement concrete. While using modifier in rigid concrete pavement, it leads to decrease in size of the elements.
