Green Concrete

Green concrete is a term for eco-friendly concrete. They are made from waste or leftover materials from various industries, and they also need less energy to produce. Compared to normal concrete, green concrete produces less CO2, is cheaper, more durable, and eco-friendly. In general, the production of green concrete is almost like normal concrete. But what makes green concrete different are the materials that replace some of the cement or aggregates. Both cement and aggregates are vital materials for concrete. Cement in green concrete can be replaced with Fly Ash, Silica Fume, and Slag Cement. Aggregates can also be replaced using plastic waste and powdered glass. The usage of green concrete itself has many benefits, such as: • Less Energy Use Portland cement production requires coal and natural gases in large quantities to heat them up. If we use some of the available waste, such as Fly Ash, it removes the need to burn raw materials into the portland cement, hence conserving energy in the production process. Fly Ash is a finely grained waste obtained from the combustion of coal. Using alternative recyclable materials like this will use less energy overall. • Reduces Carbon Dioxide Emission The smaller amount of energy needed to produce green concrete causes less emission of harmful gases into the air. Carbon dioxide plays a big role in global warming. Carbon dioxide can cause climate change, sea levels rising and changes in crops being grown. The production of cement in the entire world contributes around 4% to 5% of the carbon dioxide emitted.
