Compressive and Flexural Strength Characteristics of Paving Stones Produced with Concrete Modified with Polypropylene Waste Chair. Proceeding of the 2021 Annual Conference of the School of Engineering and Engineering Technology (SEET): Innovation and Adaptive Research in Applied Science and Engineering for Technological Application. 4th International Conference held at the Federal University of Technology, Akure, Nigeria in partnership with the University of Johannesburg. 6th – 8th October.https://hdl.handle.net/10919/124431The demand for a better performing pavement and the need to convert the ever-growing polymer waste into beneficial use necessitated the need to develop and characterize a polypropylene modified concrete for use in pavement construction. This research focuses on characterizing the strength of concrete produced with polypropylene waste as modifiers for pavement construction. The materials used in this research are fine and coarse aggregates, cement and polypropylene waste chairs (PWC). Tests were performed on the aggregate and fresh concrete to determine their suitability and characteristics for use in concrete for pavement. Two concrete grades 1:2:4 and 1:3:6 was produced into 200 mm, 400 mm and 500 mm long paving stones on which compressive and flexural tests were performed. Results obtained showed that 400 mm 1:2:4 grade concrete has the highest compressive strength of 27.36 N/mm2 at 10% polypropylene composition. The 200 mm 1:2:4 concrete grade paving stone with 10% polyprpopylene composition has the highest flexural strength of 12.90 N/mm2 . It was concluded that the 200 mm long 1:2:4 concrete grade paving stone at 10% polypropylene composition is the best length of paving stone that can give an adequate flexural strength which is the most important requirent in concrete pavement requirement.application/pdfenCreative Commons Attribution 4.0 InternationalConference proceeding
