Durability Means Longer Lasting, More Efficient Structures
Durability is a significant sustainable attribute of concrete because it will not rust, rot, or burn, requiring less energy and resources over time to repair or replace. Concrete builds durable, long-lasting structures including sidewalks, building foundations and envelopes, as well as roadways and bridges. As the most widely used building material in the world, concrete structures have withstood the test of time for more than 2,000 years. Because of its longevity, it can be a viable solution for environmentally responsible design.
When properly designed, concrete buildings can be reused or rebuilt in the future. Although a concrete building may begin its life as an industrial building, it might be renovated into office space or housing, The reuse attributes of concrete may conserve future building materials and reduce the construction time which new structures may require.
New concrete mix designs have been developed that minimize the amount of cement required while maximizing the use of alternative materials. No one concrete mix is applicable to all situations, but with the correct proportions of flyash, recycled aggregate, slag, and other materials, quality concretes can be produced that are more durable than concrete produced in the past.
