Abstract

Polypropylene (PP) is widely used in the construction industry to produce a variety of materials. Accordingly, a huge amount of waste is produced during or after the construction activity. The PP fiber provide a good alternative solution to enhance concrete properties and more sustainable concrete produced in term of isolation and weight reduction. In this study, 24 concrete cubic samples are cast adding different PP fiber content to characterize this fiber effect on concrete physical and mechanical characteristics. The results demonstrate that using higher fiber content reduced the mass of concrete extensively. However, at higher PP fiber content the unconfined compressive strength decreased compared to the controlled samples. The outcomes imply that using PP fiber contributes to the protection of environment by reducing the quantity of PP waste from construction materials.
