STUDY ON STRENGTH BEHAVIOR OF CONCRETE BLOCKS WITH FILLED UP POLY ETHYLENE TEREPHTHALATE (PET) BOTTLESVivek S., Abdul Razak. B.H. and Nikhil Khatavakar
Generation and accumulation of huge amount of plastic waste has become a silent threat to the environment and it has become a serious issue for its disposal. Plastic being a non - biodegradable, its disposal has become a major issue. In order to overcome these issues, many attempts were made to control the use of plastic in the past. But unfortunately, none of them were found to be effective. On contrary to this, one of the major problems facing that we are facing in Construction Industry is unavailability of concrete (cement, sand and coarse aggregate). Series of experiments have been conducted on plastic wastes to check its feasibility with respect to various properties of concrete like strength, ductility, durability, workability when it is partially used with concrete. Though plastic waste is considered as an urban waste or junk, but with its limited properties it can partially replace some of the conventional building material like bricks in construction industry. In some of the countries where people are under/below poverty line can construct their houses by making use of these waste Poly Ethylene Terephthalate (PET) bottles. These PET bottles when filled with waste filler material like construction and demolition waste can be used as bricks when proper casting is done with concrete mix. Various factors like execution time, cost, and flexibility, reducing waste and its utilization and energy efficiency, PET bottles have found to be more effective when compared to conventional building material like bricks or concrete blocks. Construction cost can also be reduced to a certain limit by saving the volume of concrete.
