2 Innovative Types Of Eco-Friendly Concrete

Blog

Concrete is one of the most widely used of all construction materials. Yet unfortunately, it is not exactly one of the most environmentally friendly to produce, since it requires great amounts of energy and water. Not only that, but concrete tends to release a lot of carbon dioxide during its production phase. For all of these reasons, there has been a greater and greater interest in developing eco-friendly varieties of concrete. This article will boost your knowledge of green concrete by discussing two exciting new breakthroughs currently being put to use in the construction industry.

Green-Mix Concrete

One of the principal drawbacks of concrete from an environmental standpoint is that it requires the use of lots of non-sustainable materials, with cement and sand being chief among them. Worse still, these materials tend to require a large energy input in order to process them into their appropriate state. That drives up not only the environmental unfriendliness of the final product, but also its ultimate cost.

That's where so-called green-mix concrete comes in. This project, developed by researchers at Malaysia's University Teknologi MARA, offers an eco-friendly twist on conventional concrete. Here a certain proportion of the materials used in manufacturing the concrete are replaced with green alternatives, while still conforming to the desired performance standards. The green materials include recycled aggregate, derived from non-functional concrete structures, reinforcing fibers made from recycled aluminum cans, and the substance known as fly ash. Fly ash is a coal production by product that can effectively replace cement, thus reducing the dangerous emissions associated with cement production facilities.

Carbon Dioxide Sequestering Concrete

The principal drawback of cement production is the amount of carbon dioxide it generates. Such carbon dioxide has been shown to have a deleterious effect on the earth's ozone layer. Conventional cement production releases around 0.4 metric tons of carbon dioxide for every metric ton of cement produced. This is directly tied to the incredibly high temperatures that are required to produce such cement.

Yet British researchers have found a way not only to reduce the amount of carbon dioxide produced during cement production, but to actually absorb it from the atmosphere. This is accomplished through the use of an alternative material known as magnesium sulphate. This material allows cement to be made at much lower temperatures, which is another part of its appeal. Although this technique is still in its experimental phases, it is hoped that it will soon be available for general use.

Use Concrete as a Form of Art

Concrete doesn't have to be boring. In fact it can be absolutely beautiful. My name is Andrea Reese, and I am an artist as well as an avid gardener. I enjoy sculpting and decided to try to combine my two passions to create an incredible backyard oasis. The results are incredible. In this blog, I'll show you how I learned to make small sculptures and etchings in walkways to turn what used to be ordinary concrete into something amazing that adds tremendous artistic flair to the beauty of my garden. You can make visitors to your backyard think they've stepped into a fairy land. I can show you how.
