Green concrete may be a phrase we haven’t started to hear yet. But nowadays, as climate change is becoming a greater threat, it is already being expressed as a whole new alternative on Earth. The studies led by the academicians have finally started to be implemented in practice.
Green concrete is used for concrete produced from organic concrete waste. This is an important step for a sustainable building sector and a longer life cycle. It not only saves energy, it also reduces carbon dioxide emissions and allows the reuse of waste water. So, what is green concrete?
What Is Green Concrete?
Green concrete, a revolutionary invention in the concrete industry, was discovered in Denmark in 1998. It aims to create a recycled concrete industry by using waste materials such as slag, power plant wastes, mineral wastes, waste glass, sawdust in the construction of concrete. Thus, this understanding aims to minimize the environmental impact of concrete. To this end, a new technology has been developed considering all the requirements, production processes and performance of a concrete structure. This includes the detailed calculation of the strength of the concrete to be produced, its fire resistance and its relationship to all environmental factors.
With the spread of green concrete structures, carbon dioxide emissions are expected to decrease by at least thirty percent. In addition, use of own waste products by the concrete industry will be more profitable among the ideas mentioned. It can be said that the experts draw a very positive picture about the advantages of green concrete.
Advantages of Green Concretes
As already mentioned, the most important impact of green concrete is that it minimizes the negative environmental impact and enables us to make more optimistic inferences for the future. Of course, the only useful point is not to be environmentally friendly. There are other advantages that will shake the place of conventional concrete in the construction sector. Some of them can be listed as follows:
- It will reduce the carbon dioxide emissions of the concrete industry by as high as thirty percent. It is not difficult to predict that the rate will follow an increasing graph, as this will be reflected directly in other areas of the concrete industry.
- The concrete industry will increase use of waste product and recycling by twenty percent.
- While significantly reducing environmental pollution, it will also support sustainable development plans.
- Green concrete will have a much better workability than traditional concrete products.
- Because of its high thermal resistance, it will increase the safety level in cases such as fire.
- There will be no difference from conventional concrete in terms of its resistance to water pressure.
- It will be at the same level as conventional concrete in terms of resistance to bending.
Disadvantages of Green Concretes
- Since it must be supported with stainless steel, it incurs additional costs.
- Structures built with green concrete have a shorter life span than those built with traditional concrete.
Green concrete technology does not yet possess many common uses in the industry. Therefore, in order to develop the product, it needs to be more practical and supported. In this way, the studies that may prevent its disadvantages will be paved the way.
