Effects of Addition Glass Waste on the Strength and Sound Absorption Properties of Glass Waste into Foam Concrete (GW-FC) for Wall Applications

Abstract

In contemporary times, there is a growing inclination within the construction industry to advance sustainable and eco-friendly concrete production by making use of recycled components. The proliferation of glass products has led to a substantial accumulation of glass waste, posing environmental and human health concerns. This research presents the effects of glass waste on the strength and sound absorption properties of glass waste into foam concrete (GW-FC) for wall application. The main objective is determining the optimal ratio of Glass Waste to reinforce Foam Concrete (GW-FC) suitable for wall application purposes. The methodological approach various ratios of glass waste 0%, 5%, 10%, 15%, and 20% mixed with 3% of foaming agents. The glass waste is mixed with 50% cement, 30% quartz sand, and 20% water to yield a slurry concrete mixture poured into molds for 7 days, resulting in solidified cake-like concrete. After the curing process, the cake is transformed into Glass Waste into Foam Concrete (GW-FC) designed for wall applications. The results show increasing strength when adding the composition of glass waste with a 20% GW-FC ratio stands out, exhibiting optimal outcomes achieving the highest tensile strength of 5.8 MPa and the maximum Young's Modulus at 67.34 MPa, while for the lower tensile strength 0% GW-FC at 1.12 MPa. The 20% GW-FC composition attains acceptable density at 0.013 g/cm³ and a porosity of 83%. The. For sound absorption, the 20% GW-FC is the most significant Sound Absorption Coefficient (SAC) at 0.6 α when assessed at a frequency of 5000 Hz, denoting strong sound-absorbing capabilities. GW-FC with a 20% GW incorporation level yields the most capable outcomes concerning physical and mechanical attributes for applications involving walls.
