Sustainability In Concrete Structures

Sustainability is important to the well-being of our planet, the continued growth of a society, and human development. According to the World Commission of Environment and Development of the United Nations, sustainability means “meeting the needs of the present without compromising the ability of the future generations to meet their needs” (UNFCCC COP9 Rep. 2004).

As a brief on Concrete Structures Sustainability

Concrete Sustainability means:

  • Increasing the mechanical and durability performance of concrete
  • Increasing the possible service life of the concrete structure
  • Reducing the environmental impact of concrete

Reducing the environmental impact during concrete production whilst looking at the impact on the performance and durability of the material.

Increasing the sustainability of building structures, therefore, requires both:

  • Reduction of the environmental impact during erection, maintenance and operation processes as well as
  • Increase of the durability of the structure at the maximum technical performance.

This relation can be expressed as:

Environmental Impact of Concrete
Portland cement, the principal hydraulic cement in use today, is not only one of the most energy-intensive materials of construction but also is responsible for a large amount of greenhouse gases. At the current rate of increase of cement production, worldwide cement production is expected to rise from about 2.5 billion ton in 2006 to about 5.0 billion ton by 2020. Producing one ton of Portland cement requires about 4GJ energy and Portland cement clinker manufacture releases approximately 1 ton of carbon dioxide into the atmosphere. Furthermore, mining large quantities of raw materials such as limestone and clay, and fuel such as coal, often results in extensive deforestation and top-soil loss.
