Abstract

Many researchers are currently attempting to make green concrete by substituting waste material. Utilizing hazardous industrial waste in concrete production will improve the environment. In current building construction, the use of sustainable alternatives is growing gradually. Waste glass and ceramic tiles when finely grounded create pozzolanic materials when incorporating into concrete it assesses the mechanical properties of concrete and reducing landfill waste by reusing materials in concrete production. In this study, waste glass was substituted for Portland cement at rates of 5%, 10%, and 15%. Additionally, crushed waste ceramic tiles were substituted for natural fine and coarse aggregates at rates of 10%, 20%, and 30%, respectively. A total of 90 cubes and 90 cylinders were cast. The cubes measured (15 × 15 × 15) cm while, the cylinders had a diameter of 15 cm and a length of 30 cm. The concrete specimens were examined for compressive strength, splitting tensile strength, and ultrasonic pulse velocity at 3, 7, and 28 days. The primary objective was to identify the optimal replacement levels that enhance strength performance and promote sustainability. The findings demonstrated that, in comparison with normal concrete, the adding waste glass with 10% enhancing the mechanical properties of concrete and 20% tile ceramic is ideal percentage for replacing with fine and coarse aggregate.
