Abstract
Green concrete is made from environmentally friendly waste. It reduces CO2 emissions while causing the least amount of environmental damage. Manufacturing cement accounts for 8 to 10% of total global CO2 emissions. When limestone and clays are crushed and heated to high temperatures, the greenhouse gas is released. Green concrete is defined as concrete that contains at least one component made from waste, or whose manufacturing process does not harm the environment, or which has high performance and life cycle sustainability. It cuts water consumption by up to 20%. The major factors driving the green concrete market are the reduction of carbon footprints by 40-50% during the manufacturing process, the increase in construction activities in developing countries, and the use of less water. Apart from all this it also provides excellent thermal insulation, and high level of fire resistance that enables the structure built with green concrete. Waste materials have significant potential for use in the production of green concrete. The partial replacement of ingredients with waste materials and admixtures results in higher compressive and tensile strength, improved sulphate resistance, decreased permeability, and improved durability.
