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

Sustainability - U.S. Concrete

CO 2 emission – The use of recycled materials in concrete reduces greenhouse gasses, frees up landfill space, and reduces raw material consumption. Recyclable – After a concrete structure has served its original purpose, the concrete can be crushed and recycled into aggregate for use in new concrete or as a backfill or road base.
