Green Concrete – A Review

Abstract

Green concrete is made from eco-friendly wastes. It reduces CO2 emission and creates least harm to the environment. It reduces water usage up to 20%. The major factors driving the green concrete market are due to the reduction of carbon footprints by about 40-50% during the production process, the rise in the construction activities in the developing nations and the major reason is the usage 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. There is significant potential in waste materials to produce green concrete. Partial replacement of ingredients by using waste materials and admixtures shows better compressive and tensile strength, improved sulphate resistance, decreased permeability and improved workability.
