Recycling Concrete for Sustainable Construction

The objective of this thesis is to determine if recycled concrete aggregate (RCA) can be used as a sustainable building product. The properties, uses, production, and feasibility of using RCA are first going to be identified. An overall analysis will then be made to quantify the total energy consumed to produce and re-use RCA versus
