Posted by Universidad de AlicanteResponsive · Patents for licensing · Spain

Summary of the technology

The research group has developed a cement compound that includes carbon nanofibers in cement matrix in order to detect the rate of deformation of the structure when it is subjected to external actions.

Thanks to this system can perform reliable measurements in any part of the structure without requiring the use of attached external sensors.

Innovative aspects

The technology of the University improves the existing technologies due to the use of carbon nanofibers that provide an easier to disperse homogeneously in the cement matrix without additives or additional steps in the manufacturing process.

The technology also increases the contact area matrix-nanofiber. This gives to the material more sensitive to the stress of the structure and allows more reliable measurements.
