Conductive concrete will improve aerodrome safety

A team of scientists from the State University of Iowa has developed a new type of conductive concrete.

This feature easily warms up, allowing you to quickly melt ice and snow on it.

Winter is not a good time for the airport authorities, which have to take care of the snowmaking of runways, which overlap with ice and snow. Maintaining them in good condition is a priority task, because it depends on the safety of the passengers, and yet it is not easy work.

Starts and landing planes often leave little time left to remove the snow.

Perhaps the solution to the problem will be the invention of a team of scientists from Iowa State University, led by Professor Halil Ceylan, developed a new type of conductive concrete.

The material is currently being tested at Des Moines International Airport. Two concrete slabs of 4.6 x 4.1 m were installed there. Each of them is 19 cm thick and consists of two layers.

The bottom is 10 cm and is standard concrete, while the upper one is 1 percent. Carbon fiber and a special mix of cement, sand and rocks. Between the layers there are six electrodes connected to the power supply in the hangar.

Tests have shown that applying a power of 333 W per square meter for seven hours will generate costs of 19 cents per square meter. But it is enough to melt ice and snow on the surface.
