A Sustainable Method / The Use Of Pozzolan In Concrete

Nowadays, a variety of researches are being conducted on sustainable design and manufacturing of eco-friendly materials. The cement industry is also doing supportive works on this issue in its own field. The production of cement releases carbon dioxide (CO2) and greenhouse gas emissions. For this reason, materials which may be an alternative to harmful materials such as cement are sought. Today, geopolymer has become an important topic for building technology as an eco-friendly, economic and innovative product. The structures formed by inorganic molecules by the French materialist Joseph Davidovits in 1978 were called geopolymer. Geopolymer is made from waste materials of thermal power station such as fly ash, silica dume and ground granulated blast furnace slag. Fly ash is waste or by-product obtained from thermal power plants which produce iron, steel and other metals by using coal and lignite. By using fly ash as construction material, ground improvement material and in cement production, it is possible to reduce the environmental problems and natural harm caused by formation and storage of fly ash
