It has long been considered to be the main building blocks of concrete - everyone is aware of this powder a mixture of clay, gypsum and limestone gray.
Concrete is sold by nearly every DIY stores, as well as on the market. But in the modernization of the construction industry and the emergence of new technologies to the urban development these basic building material placed increasingly stringent requirements of durability and convenience in operation. This has led to the emergence of a new generation of concretes.
A new kind of concrete differs from conventional cement stone higher strength and moisture resistance. This allowed construction companies to work in any climatic zone, as if there were not wet. Also, a new generation of concrete has an extremely frost. In the most extreme subzero temperatures it can withstand large loads, the performance properties are not lost.
But the most amazing ability of modern concrete is the strain that can be adjusted. This makes it possible to embody the life of such projects, which previously was not possible to perform. In addition, there are no problems in the acquisition of the concrete, as its popularity is growing rapidly.
But do not think that after such a "jerk" ceased to improve the building material, which, in general, there is no alternative. Progress does not stand still, it does not stop the introduction of new technologies. Therefore, most modern types of concrete that are used in various types of construction, from residential buildings to build nuclear power plants, may at any time lose its relevance. So do not rule out that very soon the production of concrete move to a new level of technology.
Scientists do not cease to experiment with already proven materials. So, scientists from the United States invented the flexible concrete that has the property of self-healing. This type of concrete even in a frozen state under pressure can bend, it does not crumble and break. Once the load is removed, there is a straightening of the concrete element, whether it is a column or plate, while the original form it was adopted. And in order to eliminate the consequences of the force action, which are microscopic cracks, small enough rain.
An unusual but promising concrete kind offered one Hungarian scientist. A wall constructed of such a material is substantially transparent because of the composition inhomogeneities which consists of conventional components, and a plurality of optical fibers different in magnitude. Through the concrete wall can penetrate the light recognizable silhouettes of subjects. The price of new, strange types of concrete yet-still high, buy concrete having similar properties are available not far from each organization. But it is very possible that in the future they will find their application, he found his new generation of concrete.
