Times change. "Green" is in consumers want environmentally friendly products, houses and buildings. The government wants to promote sustainability. To impose green building, yet not common, a premium price. The result is that the construction industry and developed with more earth-friendly products than ever before. Architects and engineers to specify design and green building green building materials more often than ever before.
Concrete is an amazing material. E 'long-term, high durability and lightweight product. And "one of the most commonly used building materials is environmentally friendly in the world. Cement is an essential component of concrete, but" dirty ". A ton of carbon dioxide is produced cement for each ton produced. It was a lot of work recently, effective through the to improve development of high-tech and green alternatives done.
In recent years some companies have made extensive efforts in
Has Calera, a California corporation, is developingan innovative method to both cement and aggregates to produce an additional component of concrete. Their method of production is unique. In the production of every ton of cement, its methods to actually remove ton 1 / 2 of CO2 in the air.
Another company in California iCrete, has a "mix design technology," is to create high-performance concrete is significantly higher than conventional concrete, developed even cheaper with lower greenhouse gas emissions. ICrete after using this product canReducing the ecological footprint of a typical construction projects by 40 percent.
A company in New Jersey Hycrete, has developed a method for permanently waterproof concrete. This method eliminates the need for and cost of using oil-based membranes underground concrete to protect the soil moisture. The process accelerates the design, helping to build, the longer and reduces the use of petroleum products.
MIT scientists have studied the structure of cementon submicroscopic. They tried to determine why older concrete and deteriorates over time. Their results suggest that in the end be able to get the durability of concrete and buildings, for about 100 years increased to many thousands of years, the less will be made concrete in the first place.
The University of Michigan has a self-healing concrete that can resist the efforts to cut much more developed than normal concrete. If the concrete heavily stressed,Microscopic cracks form.
These cracks will dry concrete where it reacts with moisture on CO2 and "scars" of calcium carbonate, which will soon cure the concrete form. A delay or even reversal of the typical process of dismantling the structures of concrete help last longer and reduce environmental impact.
Concrete is a useful and widely used building material on earth. That will not change anytime soon. Cement has properties that make it extremely useful and engineersArchitects in a wide range of applications. Innovations in the last ten years promise concrete useful, while at the same time, making it durable and cheaper to reduce pollution.
