Abstract
The environment protection related to wastes elimination and rational consumption of raw natural materials is an important target of building materials and construction industry. New materials such as eco-concrete, geopolymer concrete, eco-composites, etc. have been produced by using different types of wastes as components. Fly ash, ground granulated blast furnace slag, silica fume, tire waste, plastics, glass, agro-wastes, etc were used for replacing cement or aggregates in non-traditional concretes. Lightweight concretes can also be prepared by using wastes. In the article are presented some researches of authors that obtained lightweight concrete by using different types of wastes.
