Abstract: This paper presents experimental investigation on improvement of mechanical properties of both plain cement concrete (PCC) and fibre reinforced concrete (FRC) confined with un-plastisized poly-vinyl chloride (UPVC) pipes, which has been considered for enhancing durability of concrete structures. UPVC pipes with outer diameter 160 mm and length 300 mm have been used with three different average thicknesses viz. 2.55 mm, 4.0 mm and 5.8 mm, respectively to explore its composite performance, effectiveness in strength and ductility improvement in construction industry particularly in corrosion environment. Three series of concrete M20, M25, M30 have been designed as per the latest version of Indian Standard Code of practice IS 10262:2009. A total of 54 concrete filled UPVC pipe specimen and 27 unconfined concrete control specimen have been cast and tested using displacement controlled universal testing machine having 2000 kN capacity. The modes of deformation, load-deformation curve have been noted and detail analysis & comparison has been made with unconfined, control specimen. Attempt has also been made to study UPVC pipe confinement effect on improvement of concrete strength and the load–deformation behaviour considering both PCC and FRC.
