Abstract

Eco-green concrete emerged as an environmentally friendly solution using waste or leftover materials from various industries. One of them is the replacement of concrete constituent aggregates with materials that do not damage the environment. In this study, Eco Green Concrete innovation was made with a mixture of Submerged Arc Welding (SAW) which is the residual result of the steel welding process, concrete waste, ceramic waste which is substituted for coarse aggregate and rubber waste which is also substituted for fine aggregate with a percentage of 20% SAW waste, 20% concrete waste, 10% ceramic waste, and 8% rubber waste. The purpose of Eco Green Concrete innovation research is to determine the compressive strength of concrete and is expected to affect the estimation of more economical project costs but the quality of concrete used remains quality and environmentally friendly. The research was conducted experimentally by making concrete test objects that were tested for compressive strength at the age of 7, 14, and 28 days, 28-day split tensile strength test and 28-day bending test. Based on the compressive strength test, the results of the 28-day compressive strength test of concrete without innovation were 34.74 Mpa and 33.92 Mpa of innovation concrete. The results of the split tensile strength test of concrete without innovation amounted to 3.87 Mpa and 3.95 Mpa innovation concrete. The results of testing the flexural strength of concrete without innovation amounted to 4.83 Mpa and concrete innovation amounted to 5.22 Mpa. Keywords : concrete, substitution, waste

Abstract

This study aims to evaluate the effect of steel waste addition on the mechanical properties of fly ash-based wall panels as part of developing environmentally friendly construction materials. The main materials used include sand, fly ash, sodium silicate (Na₂SiO₃) solution, sodium hydroxide (NaOH) solution, and steel waste. The manufacturing process involved preparing the activator, mixing dry materials (sand, fly ash, and steel waste), gradually adding the activator, molding, and curing under moist conditions. The test results showed that panels containing steel waste achieved a compressive strength of 15.91 MPa, an increase of 22% compared to panels without steel waste (13.04 MPa). The flexural strength of panels with steel waste reached 4.93 MPa, an increase of 64% compared to those without (3.01 MPa). The strength enhancement is attributed to the role of steel waste particles as micro-reinforcement, which improves the microstructure, increases density, and prevents crack propagation. Therefore, incorporating steel waste into fly ash-based wall panels effectively enhances mechanical performance while supporting the development of sustainable building materials.
