Wall panels are flat and rectangular in shape and are precast construction materials used as exterior and interior walls in fast-paced constructions because of their time and labor efficiency. This research determined the desired concrete mix of cement, sand fiberglass, and shredded plastic for a lightweight wall panel that conforms to the required strength and physical properties. Quantities of sand, fiberglass and shredded plastic were varied in six designed concrete mixtures. Control mixture 1 and mixture 2 were both classed as normal-weight concrete; however, mixtures 3, 4, 5, and 6 were designated as lightweight concrete. Mix Design 3 was chosen as the best mix design, with a density of 15.79 kN/m3 and the best compression, splitting tensile, and flexure results of 15.446 MPa, 2.304 MPa, and 3.424 MPa, respectively. The density of the wall panel using mixture C was determined to be 1610.113 kg/m3and the compressive strength between 15.446 and 13.204 MPa passed the standard requirement and was way better than the conventional wall using hollow concrete blocks
