Abstract

Concrete is by far the most widely used building material, for good reasons, including strength, durability, ease of construction and many other desirable properties. However, the production of concrete requires substantial amounts of energy. In addition, the demolition of obsolete buildings generates tremendous amounts of waste. Both problems can be alleviated by recycling concrete and other materials from demolition sites into new concrete structures. The microstructure of recycled cementitious materials is even more con~plex than that of new materials. The viability of recycled materials depends to a large extent on the ability to attain durability and mechanical properties which ar
