Analisis Substitusi Pecahan Keramik dan Kawat Bendrat sebagai Pengganti Agregat Kasar terhadap Kuat Tekan Beton 4 4

Concrete is one of the most widely used construction materials, resulting in a continuously increasing demand for natural coarse aggregates. To reduce the consumption of natural resources and promote sustainable construction practices, ceramic waste can be utilized as a partial replacement for coarse aggregate, while binding wire waste can be incorporated as an additive in concrete mixtures. This study aims to analyze the effect of ceramic waste and binding wire on the compressive strength of concrete and to evaluate their potential as alternative construction materials. The research was conducted experimentally in a laboratory using K-200 concrete with a design compressive strength of 16.6 MPa. The ceramic waste was used as a partial replacement for coarse aggregate at substitution levels of 0%, 20%, and 50%, while binding wire was added at a constant proportion of 5%. The tests performed included the slump test and compressive strength tests at curing ages of 7, 14, and 28 days. The concrete specimens were prepared and tested to determine their workability and mechanical performance under the specified mixture variations. The results indicate that all concrete mixtures achieved a slump value of 10 cm, demonstrating consistent workability. At 28 days, the compressive strength of normal concrete reached 19.07 MPa, whereas concrete containing 20% and 50% ceramic waste attained compressive strengths of 18.73 MPa and 18.56 MPa, respectively. Although a slight reduction in compressive strength was observed compared with normal concrete, all mixtures satisfied the target compressive strength of 16.6 MPa. These findings suggest that ceramic waste and binding wire have considerable potential as alternative materials in concrete production while simultaneously supporting construction waste utilization and environmental sustainability.
