Abstract

Every year, millions of tons of construction waste are produced, including wire mesh that is often left unused from the cutting and installation processes. Wire mesh, which serves as a reinforcement for concrete, frequently ends up as waste. With the increasing amount of construction waste, this research proposes the utilization of wire mesh as a partial substitute for fine aggregate in concrete mixtures with variations of 0%, 5%, 7.5%, and 10% by weight of sand, targeting compressive strengths of 21 MPa and 25 MPa. Additionally, 8% fly ash and 0.5% superplasticizer by weight of cement were used. Test specimens were cylindrical, with a diameter of 15 cm and a height of 30 cm, and were tested for compressive strength after 28 days. The results showed an increase in compressive strength of 36% and 9% for concrete grades of 21 MPa and 25 MPa, with the optimum percentage of wire mesh addition being 5%, which resulted in compressive strengths of 33.20 MPa and 31.73 MPa, respectively. However, the compressive strength significantly decreased at the 10% wire mesh variation, with average compressive strengths for the target grades of 21 MPa and 25 MPa being 23.67 MPa and 16.43 MPa, respectively.
