Smart Cement: Development, Testing, Modeling and Real-Time Monitoring [Paperback]

Over three billion metric tons of cement are produced annually worldwide, making concrete the most extensively used construction material. Self-sensing, or smart, cement allows real-time monitoring of performance through the entire service life of a concrete structure, for the detection of changing stresses, contamination, excessive temperature, gas leaks and pre-seismic activity. This is achieved by adding a very small proportion of conductive or semi-conductive fibers, such as carbon fibers to the bulk cement, making it piezoresistive, and enabling changes in the concretes electrical resistivity in response to shear stress and strain to be monitored.

This state-of-the-art reference work presents experimental results with a realistic theoretical framework, for cement manufactures, concrete technologists and contractors as well as researchers.

Smart cement is a chemo-thermo-piezoresistive material that functions as a highly sensing 3-dimensional bulk sensor. It can be used for monitoring changes oflectrical resistivity in concrete by the addition of 0.03% of selected conductive or semi-conductive fibers are added to the bulk cement.
