There have been efforts to use building demolition waste as an alternative aggregate in concrete to decrease the use of natural resources for construction. The World Green Building Council estimates that the construction industry is responsible for more than 50% of all material extracted globally and that construction and demolition …
Promoting recycled aggregates from construction and demolition (C&D) waste for producing concrete will reduce the demand on conventional aggregates and it is an alternative to effectively manage C&D waste. Application of recycled C&D aggregates as a substitute to conventional aggregates in low strength concretes is the best way to …
1. Introduction. It is generally agreed that construction and demolition waste (CDW) management practices should be guided by the "3R" – reduce, reuse and recycle – principle (Peng et al., 1997).However, the effectiveness of embracing such practices in China, where CDW accounts for about 30%–40% of the total municipal …
