What is green concrete mix? Green concrete mix is designed with the principle of “Particle-Packing Optimization” to meet requirements of plastic and hardened properties. Green construction materials are composed of renewable, rather than non-renewable resources. Green materials are environmentally responsible because impacts are considered over the life of the product.What is green concrete and how does it affect the environment? Green concrete has greater strength and durability than the normal concrete. It is realistic to assume that the technology can be developed, which can reduce the CO2 emission related to concrete production. Generally the construction industry accounts for a massive environmental impact due to its high demand of energy.What are the alternative environmental requirements for green concrete structures? There are a number of alternative environmental requirements with which green concrete structures must comply: CO2 emissions shall be reduced by at least 30 %. At least 20 % of the concrete shall be residual products used as aggregate. Use of concrete industries own residual products.
