Studies [25,26] confirm that using concrete frames leads to marginally more economic buildings than those constructed with competing materials. Concrete frames also provide the inherent benefits of fire resistance, excellent acoustic and vibration performance, thermal mass and robustness – all at no extra cost.
Cement Industry Economic Impact By State. State map facts sheets stress the contribution of the cement and concrete industries to the state and local economy.
While environmental sustainability is an integral part of the Lisbon strategy, protection of the environment and economic growth are often seen as competing aims. Proponents of tighter environmental regulation challenge this view. They highlight the financial benefits of increased eco-efficiency and the emergence of a European eco industry
Most of the other ingredients such as fly ash, slag, and silica, can be obtained as waste from various manufacturing processes. Because of this, the material impact of concrete on the overall environment is minimal. However, the production of concrete does require thorough mixing of very heavy materials.
May 01, 2005 · Environmental and economic performance are combined into an overall performance measure using the ASTM standard for Multi-Attribute Decision Analysis. The paper will explain the BEES approach and illustrate its application to alternative concrete products with and without supplementary materials.
A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete. The cement industry is one of the primary producers of carbon dioxide, a potent greenhouse gas. Concrete causes damage to the most fertile layer of the earth, the topsoil .
Various methods to reduce environmental impact of concrete such as material conservation is discussed. Concrete has a substantial environmental impact. For example, it is estimated that 1.6 billion ton of concrete is produced annually which is responsible for about 7% carbon dioxide in addition to depletion of natural sources and dumping ...

The Effects and Economic Impact of Corrosion CORROSION is a natural process. Just like water flows to the lowest level, all natural processes tend toward the lowest possible energy states. Thus, for example, iron and steel have a natural tendency to com-bine with other chemical elements to return to their lowest energy states.
Abstract: Concrete is a major material used in the construction industry that emits a large amount of substances with environmental impacts during its life cycle. Accordingly, technologies for the reduction in and assessment of the environmental impact of concrete from the perspective of a life cycle assessment (LCA) must be developed.
