Assessment of Concrete Compressive Strength by Adding Fiberglass and Shredded Plastic

Abstract

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
