1. Recognize increasing pace of concrete technology
development and its implementation within the
industry
2. Discuss applicability of various concrete
technologies to green-building systems and
sustainable design
3. Evaluate positive and negative elements from both a
concrete supply and contracting point of view
4. Identify challenges that technologies and green-
building requirements bring to the construction
process
Learning Objectives

Green Building & Sustainable Design
• Design and construction practices to
– Reduce or eliminate impact of buildings
on environment and occupants
• Five Broad Areas:
– Sustainable site planning
– Safeguarding water efficiency
– Indoor environmental quality
– Energy efficiency and renewable energy
– Conservation of materials, resources

Benefits of Green Building
• Environmental benefits
– Reduce impacts of resource
consumption
• Economic benefits
– Improve the bottom line
– High benefit at low cost (?!?!?)
– Optimize life-cycle, utility costs
• Health and safety benefits
– Enhance occupant comfort, health
• Community benefits
– Reduce strain on infrastructures

Technology Example - HVFA
• What happens over 30%?
– History is not kind…
• Why not 40%, 50%, 60%?
• Equal performance
– Set time, strength, etc.
• Changes in contracting
– Finishing, curing, etc.
• Proprietary Mix Designs

Reflective Concrete…Cool Pavements
• Higher reflectivity reduces air
temperatures
– 0.1 increase 10oF decrease
– Heat island effect
• Solar Reflective Index (SRI)
– ASTM E1980
• “Albedo” is unit of measurement
– ASTM C1549
• When are they measured?

Reflective Concrete…Cool Pavements
• Time and expense of testing
• Function of available materials
– Test panels are critical
– No historical data
– Beware the “this combination worked
on the last job…”
• What if it does not work?
– Contract liabilities?
• Sunset provisions in Contract

• Non-segregating
• Free flowing
• Not a new concrete!

Recycled Water and Stormwater
• The problem we all have…
• …we are at zero discharge
• Why would a specification
not support its use?
• Batch panel controls
• Document each load

Green Cement
• Based on emissions from
cement
• Requires contractor/supplier
certification/verification
• More limited/specialty a
source material…
– more expensive it could become
– greater potential concrete
expense
“…A cement kiln
that has met the
emission standard
of 1.7 lb of NOx
per ton of clinker
released into the
atmosphere…”

Opportunity: Proprietary Mix Designs
• Prescriptive vs. Performance
• Let the best technology win
• Performance basis?
– w/cm vs permeability, etc.
• Commodity to engineered…
• National focus, NRMCA

Issues and Challenges
• Our industry does not
like change
• Green Building is Architect
and Owner Driven
– Industry giving input?
• Industry Communication?
– Engineers
– Contractors
– Testing Labs

Issues and Challenges: Engineers
• Green Building = Performance
• What performance is needed?
– Verification of performance
– Do your homework
• Be explicit, not implicit!
– Set time
– What strength at what day?
• Must see the mix design…why?

Issues and Challenges: Architects
• Often don’t understand own
