Improvement of the Environmental Energy Sustainability in the Production of Cement Portland with Addition of Thermally Activated Clays

Assessment of Clay Brick, Hollow Brick and Roof Tile Provided from Assorted Construction and Demolition Waste in Geopolymerization

“…Çimento endüstrisinde klinker üretiminin enerji tüketiminden ve karbondioksit salımından dolayı, aynı zamanda alternatif hammaddelerin de değerlendirilmesi düşüncesiyle zaman içerisinde katkılı çimentoların kullanım oranı artmıştır. Katkılı çimentolar bünyelerinde daha az klinker ihtiva ettiği için klinker talebini doğrudan azaltan bir yöntemdir [3]. Ayrıca beton üretimi sırasında mineral katkıları çimentoyla ikame ederek de portland çimentosuna dolayısıyla klinkere olan talebi azaltmak mümkündür.…”

Study on utilization of zeolite in concrete precast industry

“…Trends in environmental protection in every production, transportation and other industry fields lead to minimize the carbon footprint achieving by CO2 emissions reduction to the lowest values. In the concrete production, cement from portland clinker, as its main component, is considered to be the most demanding from the energy consumption point of view and subsequently from the environmental pollution contribution point of view [1,2,3]. With the aim to reduce the content of pure clinker in the cement, some mineral additives with pozzolanic (like fly ash, metakaolin, zeolite, silica fume) or latent hydraulic (like ground granulated blast furnace slag GGBS) properties are added directly to the cement as supplement or during concrete production as additive [4,5,6,7,8,9].…”
