Use of plastic has increased to a great extent due to rapid growth and urbanization and thus generation of plastic waste due to it has resulted in many problems such as its disposal and many health & environmental problems. Among these plastic, polyvinyl chloride (PVC) is most hazardous one. Hence, this thesis deals with strengthen concrete by plastic covering aggregates as a partial replacement of coarse aggregates and a way to reuse waste plastic. Here, PVC pipe shells of approx. 1 inch cutting and internal & external dia. of 16mm & 21mm respectively, filled with 1:3 mortar, is used and termed as plastic aggregates. Almost 24 specimens of concrete were prepared, the concretes indirect split tensile strength and flexural strength (modulus of rupture) and their behavior is investigated along a time span of 7 days and 28 days with 10% replacement of coarse aggregates with High Density Polyvinyl Chloride waste plastic aggregates and also a sort of Portland pozzolanic cement with 30% fly ash. Result shows that the Indirect Split Tensile Strength of concrete for M25 grade at 7 days with 10% replacements shows fulfilling minimum satisfying criteria compared to basic values of M25 grade concrete but reduces to small extent of even min. satisfying criteria for 28 days of curing. Whereas, flexural strength Result shows that at 7 days a huge fall in strength to basic values, but gains strength to a good extent at 28 days of curing but still below or nearer to min. satisfying criteria.
