Longevity & Durability

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

This presentation discusses Social Value #5:

Longevity/Durability

Concrete is one of the

most durable, long-lasting

building products

available.

Minimal maintenance

Ease of Repairs Extends Service Life

• Cabrillo Bridge, San Diego, CA – on National Register of Historic Places - Built in 1914

• Renovated in 2007

Typical car =11,760 lbs of CO2

per year

Concrete Driveway (24’ x 50’) =5,880 lbs (initally)

Considering a 30 year life span – under 200 lbs per year

Durability is the Denominator

Durable is Sustainable

• Optimal material utilization– less waste from replacement

• Lower maintenance costs and construction congestion

• Lower total cost of ownership• Long life = smaller eco-footprint

• Building structures and infrastructure that will last with minimal maintenance, and preserving historic structures, are critical to the health and well-being of future generations.

• Durable, long-lasting structures minimize the impact on our dwindling natural resources.

• Preserving historic structures is not only cost and resource effective, it is a way for us to maintain a living connection to our history.

For Now and Future Generations
