The V. V. Voevodsky Institute of Chemical Kinetics and Combustion SB RAS and the S. S. Kutateladze Institute of Thermophysics SB RAS have developed an innovative smart composite based on cenospheres of ash (formed during coal combustion at thermal power plants). This material can be used in construction as a sensor.
Cenospheres are a by-product of coal combustion that were considered waste. However, a useful application has been found for them.
A capsule with the material is placed inside, for example, a bridge support, where it will be under constant external pressure. As soon as the pressure reaches a critical value, the conductivity switches and the sensor is triggered, transmitting information about a possible problem, such as a threat of collapse.
The developed composite controls conductivity depending on pressure fluctuations. This makes the materials ideal for use in drilling, where controlled conditions and safety are critical.
Earlier www1.ru reported that a shock-resistant composite made of steel was developed in Irkutsk.
