I know you are already amazed at reading the title of this article and are already wondering what explanation I have to give to you for such a proclamation. Concrete is one of the most essential discoveries in the concrete industry and is being used in the buildings constructed all over the world for the past 150 years. The mixture used in buildings has seen a lot of changes over the history of building constructions and concrete itself has gone under major improvements since the time it was first introduced. The changes that have been brought have in many ways made concrete environmentally safe and secure.

In the past fifty years as result of various movements and the awakened conscience of the public there has been a green revolution of sorts which has seen people come up with ideas to make the products offered in the market more and more eco friendly. After, the widespread popularity of these products there prices have become reasonable making them usable by more people. The construction Industry has also gone through the same change of bringing in eco friendly building solution and an eco friendly concrete is one of its results.

Given the above explanation many people still misunderstand concrete to be a product which damages the environment and causes lots of problems. Let’s begin with explaining why it is that concrete is environmentally friendly; the cement-concrete mix design is made up of Water, Rock, Sand and Cement. Water, is used for the hydration process it helps in binding all the other three materials together in a good mix. The water should always be clean but not necessarily portable. Water therefore requires no additional purification and the extra water used gets evaporated or goes back to the groundwater system, making it perfectly renewable.

The next material rock which is found in concretes can be brought from anywhere, it does not necessitate drilling of mountains, and rocks by the pavements can be used for making the cement-concrete mix design. More often than not rocks are used from local sources, which save transportation costs and other resources. Rocks from remains of Blast furnaces or digging can be easily used. Sand is another material which is plentiful, cheap and renewable. Sand and rocks make up for 70% of the cement-concrete mix design and since they both are renewable they help in keeping the environment clean. The last material used, that is, cement is a material which does use a lot of energy in its production and therefore there are efforts to find new sources of cementization like fly ash which is a waste product of power plants and can be reused.
