has created a new type of concrete is repaired only when there are cracks. According to its creators enough that water and carbon dioxide do their job, no need for all human intervention.
Thus, a few days of rain would serve to repair, for example, a bridge built with the concrete.
This self-healing is that the material is designed to bend and break into jagged lines. New concrete
bends without breaking. Is protected by coated fibers that hold it together, so can remain intact and safe when deformed up to 5 percent of its original size. Not even a major earthquake that pressure exerted.
When exposed on the surface of the cracks may react with water and carbon dioxide from the air and form a thin scar "white calcium carbonate. Calcium carbonate is a solid compound found naturally in the shells.
Today, builders reinforce concrete structures with steel bars to keep the cracks as small as possible, but these are not small enough to prevent water and ice from penetrating and damaging the steel, weakening the structure. However
this concrete does not require steel reinforcement to keep small cracks, as described above and corrosion does not occur. Therefore
substance may make infrastructure safer and more durable. Reversing the typical deterioration process of self-repair processes, the concrete would reduce the cost and impact on the environment causes the development of new concrete structures.
