Additional polypropylene fiber mesh (PFM) effects on bending moment, compressive strength, and workability of concrete

It is alarming that an overwhelming 35.46% of unmanaged garbage comprises plastic waste, amounting to 10,129,984 million metric tons. It constitutes approximately 15.6% of the total waste globally. Immediate measures must be taken to curb our plastic consumption and ensure its proper disposal to safeguard our planet. Even though plastic scrap is challenging to recycle, it harms the environment. Instead, using plastic waste as an addition to cement manufacturing becomes a good solution for the construction industry. Concrete’s brittle qualities have an impact on the bending moment. Hence, adding fiber is a solution to this problem to improve the mechanical properties of concrete. Polypropylene is a thermoplastic fiber that can be added to strengthen the concrete’s ductility and increase its compressive strength and bending moment value. Experimental tests are conducted to achieve this. f’c 25 MPa of compressive strength with a mixed design using polypropylene The compressive strength of the 15 cm x 15 cm x 60 cm fiber beam specimen increases significantly. The average compressive strength of the concrete mixture using PPF 0.7 kg/m3 was increased for fourteen days, reaching 27.93 MPa and 30 MPa for 28 days, respectively. Compared to regular concrete, compressive strength rose from 9.53% to 9.69%. The bending moment is increased, reaching 11231116.95 N.mm at 14 days and 13796629.6 N.mm at 14 days, respectively. Instead, it can reduce the workability of fiber concrete.
