Resource Efficiency

The Concrete Joint Sustainability Initiative is a multi-association effort of the Concrete Industry supply chain to take unified and integrated action for Sustainable Development

Concrete JSI members have signed a joint agreement committing to act on 9 Declarations. Declaration #4 addresses 8 Social Values of Concrete Structures

Declaration #4: “Our integrated thinking will focus on the following Social Values provided by Concrete Structures”: 1. Resource efficiency5. By-product reduction 2. Safety/protection6. Aesthetics 3. Financial responsibility7. Societal connectivity 4. Operational continuity8. Longevity/durability

What it means Concrete Structures over their lifecycle are efficient users of energy, water, land and other resources Social Value: Resource Efficiency

Materials Resources  Durability  Recycled Content Energy Resources  Locally acquired  Structures and pavement Water resources  Pervious pavements Resource Efficiency

 Cost savings by not finishing floors, walls, etc.  Structure, air barrier and finish in one integrated system  Easily repairable Resource Efficiency Photo courtesy of L. M Schofield

Integrated Design = Success!

4,000 psi vs 9,000 psi concrete?  Additional 3,120 rentable square feet  16% less cement  1,730 yards less concrete  3,400 tons less weight Reduce CO2 by 220,000 lbs Design Flexibility / Optimization

Energy Resources Did you know? Average distance between manufacturing and project site is only 14.2 miles?

Concrete roads:  Minimize urban heat island effects  Have lower rolling resistance  Require less fuel during construction Energy Resource Efficiency

Concrete bridges and other infrastructure  Durability  Accelerated construction schedule  Reduced maintenance Resource Efficiency

Land and Water Resources

Reduction of floor and wall finishes  Improved thermal comfort  Reduced sound transmission  No food source for mold growth Resource Efficiency

125+ million tons/year Cradle to Cradle

 Integral waterproofing  Photo-catalytic concrete  Nanocements  Seawater-based cement and aggregates Looking Forward

 New supplemental cementitious materials, such as rice husk ash  Light-transmitting concrete  Carbonation research Looking Forward

 Fundamental to sustainability for future generations  Durability and efficiency affects both maintenance and replacement  Extends beyond construction materials to include water, land use, and energy Summary
