Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of a significant amount of carbon dioxide, a greenhouse gas. It also leads to depletion of aggregate and water resources.Environmental issues are playing an important role in the sustainable development of the cement and concrete industry. A sustainable concrete structure or infrastructure is constructed to minimize the environmental impact through its life cycle. Concrete is considered a sustainable material. It has low inherent energy requirements; it is produced with little waste and from plentiful resources; it can be made with recycled materials and recycled crushed aggregates; and it is recyclable itself. Many recycled materials used in concrete – from recycled water, recycled aggregates, and recycled by-product materials – can be implemented in many different concrete structures.

The contents of this course include five recorded presentations from the ACI 2015 Fall Convention:
• Recycled Concrete Aggregate a Sustained Choice for Unbound Base by Cecil Jones, Diversified Engineering Services Inc., Raleigh, NC
• Role of Quality of Recycled Concrete Aggregate on Durability and Long-Term Performance of Concrete by Medhat Shehata, Ryerson University, Toronto, Ontario, Canada
• Benefits of Saturated Recycled Concrete Aggregate Inclusion in Concrete by Daniel Pickel, University of Waterloo, Waterloo, Ontario, Canada
• Self-Consolidating Concrete Prepared with Recycled Concrete Aggregate and Recycled Asphalt Pavement by Yasser Khodair, Bradley University, Peoria, IL
• Concrete Plates Made with Fiber-Reinforced Rubber Concrete by Alessondro Fantilli, Polytechnic University of Turin, Turin, Italy

1. Demonstrate how to evaluate concrete mixtures with various waste by-product and recycled materials.
2. Identify the properties of concrete that are affected by using RCAs.
3. Identify examples of successful projects where concrete made with recycled materials performed adequately.
4. Describe emerging technologies in concrete produced with recycled materials and its application in civil infrastructures.
