Abstract
An idea for concrete recycling is proposed for the 21st century. When demolished concrete is crushed after heating, aggregate is obtained with satisfied qualities for concrete without destruction of the shape. For produced powder, the chemical composition is presumed. The possibility of recycling cement with reducing of limestone is shown. If thus concrete recycling included cement and aggregate is done, resources and carbon dioxide discharge are reduced. Before long, the external diseconomies like these will be reflected the cost of product. Concrete recycling included cement should be intended for reducing external diseconomies for environment.
