Green Concrete

| Traditional ready-mix concrete is a significant cause of production of GHG (Green House Gases), less in regards to GHG emissions per m3, but in particular in regards to the high quantity produced world-wide. New available technologies allow the use of different types of concrete and advanced ways of production which represent a lesser hazard to the environment. In the life-cycle of concrete there is plenty of room for improvement towards sustainability that starts from sourcing the materials and goes as far as using innovative systems imposing fewer burdens on the environment for the concrete cooling and the usage of renewable energy sources for primary energy consumption. The method of production and extensive usage of concrete on building sites allows achieving a significant number |

of LEED (Leadership in Energy and Environmental Design) points, to decrease the carbon footprint and to optimize the usage of energy.
Concrete remains less harmful than most other common building materials, but as the quantity of concrete used in construction is fairly higher than the quantity used of other building materials, improvement in the concrete production process and its application has a great effect on the total environment burden that arises out of building construction.
A combination of different existing green technologies and an optimization on energy consumption hence can make a concrete batching plant an environmental friendly undertaking.
Generally the construction industry accounts for a massive environmental impact due to its high demand of energy. The cement industry and, as more specifically discussed in this paper, the production of ready-mixed concrete stands for a significant part of carbon footprints in the construction sector, mainly due to the high energy consumption of the transportation of building materials.
As a result of the awareness built during the past few years about green house effect and damage to the nature, more people and countries became conscious about their future and the future for the coming generations.
Increasing interest in the reduction of CO2 emissions in the United States and Europe and the heavy environmental impact due to increasing energy consumption and over-usage of fossil fuels has led the government in Qatar to focus on alternative solutions and to promote a more environmentally-friendly approach to 'doing business' to the country's numerous local and foreign investors. |
