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
http://www.sustainableconcrete.org
Declaration #4:
“Our integrated thinking will focus on the following
Social Values provided by Concrete Structures”:
1. Resource efficiency
5. By-product reduction
2. Safety/protection
6. Aesthetics
3. Financial responsibility
7. Societal connectivity
4. Operational continuity
8. Longevity/durability
Social Value: Resource Efficiency
What it means
Concrete
Structures over
their lifecycle
are efficient
users of energy,
water, land and
other resources
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

concrete?
 Additional 3,120 rentable
square feet
 16% less cement
 1,730 yards less concrete
 3,400 tons less weight
Reduce CO2 by

Energy Resource Efficiency
Concrete roads:
 Minimize urban
heat island
effects
 Have lower
rolling resistance
 Require less fuel
during
construction
Resource Efficiency
Concrete bridges
and other
infrastructure
 Durability
 Accelerated
construction
schedule
 Reduced
maintenance
Land and Water Resources
Land and Water Resources
Resource Efficiency
Reduction of floor
and wall finishes
 Improved thermal
comfort
 Reduced sound
transmission
 No food source for
mold growth
Cradle to Cradle
125+ million tons/year
Looking Forward
 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
Summary
 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
