Abstract
Self-compacting concrete (SCC) is a flowing concrete that does not require vibration and should not be vibrated. Palm oil fuel ash (POFA) is a by-product obtained during the burning of waste materials such as palm kernel shell, palm oil fiber, and palm oil husk. It can be utilized to partially replace cement in a concrete mix considering its good pozzolanic properties and high performance in the development of strength of concrete. This work highlights the scope of finding the properties of M40 equivalent (considering structural applications) fly ash based self compacting fiber reinforced concrete in cooperating waste carpet polypropylene fibers and palm oil fuel ash. Cement is replaced with palm oil Fuel Ash at 10, 20, and 30% by weight of cement and optimum percentage of palm oil fuel Ash is found. In the self compacting Concrete mix having optimum percentage of palm oil fuel Ash, Polypropylene carpet fiber fractions at 0.25, 0.5, 0.75, 1% by volume of concrete are incorporated and the optimum percentage of addition of waste carpet fibers is found by testing the mechanical properties. The fresh and hardened properties of the M40 equivalent fly ash based self compacting fiber reinforced mix with optimum palm oil fuel ash and optimum waste carpet fibers were compared and evaluated.
