The Influence of Waste Plastic Fiber on the Characteristics of Light Weight Concrete with Expanded Polystyrene (EPS) as Aggregate

This research aims to create lightweight concrete mixtures containing waste from local sources, such as expanded polystyrene (EPS) beads and plastic fibers (WPFs), all are cheap or free in the Republic of Iraq without charge. The modern, rigid, mechanical properties LWC were investigated, results evaluated. Three made, each with different proportions (0.4%, 0.8%, 1.2%), addition a mixture steak mixture. It contains 20% EPS. study found that caused by WPFs reduced density (lightweight) because EPS tends form more blocks, absorb water, dry While increase WPF content increased compressive strength, strength mix was only 13.6 MPa, 17.6 MPa when added. also bending resistance, where resistance 2.26 2.66 (WPFs)
