|Project duration||September 2016 - October 2019|
|Venture||The strategic innovation program InfraSweden|
Purpose and goal
The following main objectives of the project were reached: 1.SmartCem was synthesized within the project and material was solidified into conductive and sensitive matrix 2.Prototype monitoring system based on SmartCem material was developed 3.Effects of synthesis parameters on properties of the SmartCem were determined. 4.Dependency between stress, strain, temperature variations, crack formation, humidity variations and piezoresistive response was determined. 5.Full scale reinforced concrete element is monitored by the developed SmartCem m
Expected results and effects
The main output of the project is a novel material and technology enabling to build new smart self-monitoring concrete structures. The technology can be used to produce sensors which properties will be comparable with the monitored materials. For example the water to cement ratio, type of cement, type of sand and other admixtures used for the sensor and for the concrete use in the structure will be the same. The life span of the new monitoring systems based on the developed technology will be the same as of the monitored structures. The material can be used also to make whole structures.
Planned approach and implementation
The implementation of the developed technology into real life applications will be done after further more extensive full scale testing planned in the follow up project to be established for the years 2021-2022. During that time a s possible spin-off company might be established in cooperation with number of industrial partners.
