Ecological aspects of concrete production

Concrete industry is now the largest consumer of natural resources and one of the largest producers of waste. Only in Europe, the annual production of concrete is over 750 million m3 and that is 4 tonnes of concrete per capita. Although concrete itself as finished material does not have harmful effect on the environment, production of concrete components has influence on the environment. In the process of production and use of cement, aggregate and water in concrete, ecological aspects should be considered. Different aspects of making concrete production more environmentally friendly are analysed in the paper. Possibilities of using blended cements, new types of binders, recycled aggregates and treated waste water have been shown. Ecological aspects in concrete industry are: lowering CO2 emission, conservation of natural resources, and construction of more durable concrete structures.
