The Environmental Benefits And Uses Of Green Concrete
What Is Green Concrete?
Green concrete is manufactured from eco-friendly waste material such as plant wastes, slag, recycled concrete, red mud, foundry sand, etc. The manufacturing process involves less energy usage, and less carbon dioxide is released into the atmosphere than the case is with standard concrete. Another term for green concrete is “resource saving structures with a lesser environmental impact” for example, Energy saving, wastewater, and CO2 emissions.
Dr. WG from Denmark initially invented green concrete in 1998.
The reason why this concrete is green is due to the extra steps the company has taken when the concrete is mixed and ensuring a sustainable structure as well as a long life expectancy with a low maintenance surface. The aim behind the Centre for Green concrete is to lower the environmental impact of manufacturing concrete. To achieve this, new technology was developed relating to all steps of constructing concrete’s life cycle, i.e., specification, structural design, manufacturing, and maintenance.
What Are The Environmental Benefits Of Using Green Concrete?
Green concrete advances in strength quicker and has a lesser rate of shrinkage than concrete which is made from Portland cement. Structures that are erected by using green concrete has a better probability of surviving a fire since it can withstand high temperatures going up to 2400◦F. It also has a higher resistance to corrosion which is essential when you think about the adverse effect that pollution poses to the environment. Acid rain significantly impacts the longevity of customary building materials. All these factors make a vital difference when you’re building structures to last for much longer. When you’re not constantly having to rebuild, fewer materials used for construction purposes are required therefore reducing the impact it has on the planet.
Reducing Energy Consumption
If you are using less of your regular cement and more fly ash when you’re mixing concrete, you are using less energy. The materials used in cement necessitate large amounts of natural gas or coal to heat. Fly ash is a by-product of another industrial process; therefore, you are not disbursing more energy to use it when producing green cement. Another great benefit of using green concrete is the building of structures that are longer-lasting and more resistant to temperature fluctuations, therefore, saving the cost of cooling and heating expenses.
Reducing Carbon Dioxide Emissions
Among the key ingredients in ordinary cement are clay, pulverized limestone, and sand which are heated at high temperatures. The process involved in making cement is generating a percentage of between five and eight percent of all carbon dioxide emissions all over the world. On the other hand, the manufacturing process for creating green concrete releases up to eighty percent less of carbon dioxide emissions. Switching to green concrete permanently for construction projects can make a substantial difference as a global effort to reduce emissions.
Where Is Green Concrete Applied?
- For constructing bridges
- It is extensively used in the building construction
- For building column
- It can be used for road construction
