Green Concrete - A Sustainable Solution

Concrete which is a structural material consisting of particulate substance, like fine and coarse aggregate, cement and water, that is bonded together in a standard mix ratio. Concrete is one of the most used construction materials around the world for building construction. For shaping a building, concrete is having a mandatory role but the usage of concrete causes for environmental impacts likes global warming. Cement is the major constituent material in the concrete and the reactions happening in the concrete is exothermic reaction, it is heat generating reaction and evolvement of gases which is harmful and causes environmental imbalance. Production of concrete is one of the vital factors for global warming as it accounts for 30 % of the total CO2 released in the atmosphere. Recycle and reuse of waste materials from industries is becoming very popular to overcome these environmental issues. In order to compensate these effects, an eco-friendly concrete must be substitute, this compensating concrete is known as green concrete. Due to the development in the sustainable construction, engineers and architects are stimulated to figure out the materials which are more sustainable for construction. This paper reveals about the green concrete, its materials& selection, advantages and disadvantages of green concrete technology.
