Use of Plastic for Sustainable Concrete

Disposing of plastic waste in the environment is seen as a major problem due to its low biodegradability and abundance. Recently, research has been carried out on the treatment of these wastes with large stones, where the durability of the concrete will be an important consideration. The use of plastic has the advantage of low consumption and to some extent solves the problem of plastic waste. Plastic waste can be mixed into concrete in some way without affecting other materials and without affecting its strength. In this investigation the mix design is carried out as per IS 10262: 2009 for M25 grade. Shredded plastic in the form of flakes in 0%, 10%, 15% & 20% are added and the optimum percentage at which higher strength is obtained is calculated with water cement ratio of 0.39. Ordinary Portland cement, Conplast SP-430 super plasticizer is used
