Eco-concrete: Maximizing strength and minimizing implications of crushed over-burnt on the environment brick substitution

Concrete is commonly used in construction, but its dependence on natural aggregates like sand and gravel raises concerns about resource depletion and environmental impact. The need for ecologically appropriate replacements is rising as these resources become scarcer and more expensive. Crushed over-burnt bricks from artisanal brick kilns may work. Traditional concrete aggregates can be substituted with these bricks, which are usually discarded due to fire damage. Research shows that replacing natural aggregates with 30% over-burnt bricks improves concrete mechanical properties. Over-burned bricks enhance the compressive strength of concrete by 20%, reaching 45 MPa. Tensile strength and workability increase by 10% and 12%, respectively, making the mix more manageable. Overburned bricks provide environmental benefits as well as mechanical performance. This replacement reduces concrete production’s carbon footprint by 18%, reducing the need to mine and quarry natural aggregates. Reusing abandoned things reduces landfill rubbish and promotes a circular economy. Over-burned bricks minimise water absorption and porosity, making concrete more weatherproof. This technology is cost-effective and environmentally friendly, especially in areas with few or expensive natural aggregates.
