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

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

This presentation discusses Social Value #5: Longevity/Durability

Concrete is one of the most durable, long-lasting building products available. Longevity/Durability What it means

From homes to high rises

Longevity/Durability What it means Lower maintenance requirements Less construction traffic delays More productivity

Longevity/Durability Pavements

I-10 west of Los Angeles – Originally built in 1946 as part of US Route 66 – Ground in 1965, 1984, and 1997 – After 63 years, still handling 240,000 vehicles/day… Longevity of Concrete Highways

Minimal maintenance and repair during service life

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 CO 2 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
