Electrically conductive concrete will melt the snow without chemicals in US airports

The special concrete mixture, which melts the snow without chemicals, using electricity, may soon appear in US airports. The mixture created by researchers from the University of Nebraska-Lincoln, for the most part - normal concrete, but 20% of it - steel chips and carbon particles. This makes the coating sufficient electrical discharge snow melting, but safe to the touch.



The Federal Aviation Administration United States is studying the invention of engineer Chris Tuan (Chris Tuan) - electrically conductive concrete - and plans to test it in one of the airports. To the surprise of the developer, the authorities do not want to put this on the concrete runways. Instead, the new concrete will have outputs to provide a comfortable work of staff responsible for baggage, for food, garbage collection, delivery of fuel. In the opinion of management, it will greatly reduce the number of delays due to weather conditions.

Concrete from Tuan is already in use at a particular facility - together with the road department Nebraska inventor equipped the bridge 52 slabs of concrete that , and now cover this bridge does not freeze. Tuan notes, which is disadvantageous to cover a concrete object completely, but you can use it in certain places who were the first freeze.

From an economic point of view, this concrete bridge with far more advantageous than the use of traditional means of melting snow: in three days the storm and active "work" of concrete burns $ 250, which is several times cheaper than the truck with chemicals
.
Another side benefit of concrete - it does not conduct electromagnetic waves. It can be fun to companies for protection against industrial espionage.

The inventor himself enjoys such concrete - in the backyard of the house Tuan they lined patio.
