green concrete

An environmentally friendly version of concrete produced with either non-CO2-emitting materials and/or non-CO2-producing methods. One of the most commonly used methods is to use indus-trial waste by-products such as fly ash from coal combustion and blast furnace slag from iron manufacturing to constitute the cement mixture used in producing concrete. One of the main advantages of this method is that it prevents these waste materials from entering landfills. See also: Biomaterials
