Summary of the technology
NARPS is an innovative hand-held, non-destructive instrument for the detection of chlorides and carbonation in reinforced concrete.
New and innovative aspects
Reinforced concrete, containing embedded steel reinforcement, is widely used in all forms of civil infrastructure. Over time, the steel bars can begin to corrode. Researchers in Dublin Institute of Technology’s Civil Engineering Research Group (CERG) have developed an innovative hand-held, non-destructive instrument (NARPS) for the detection of chlorides and carbonation in reinforced concrete.
Main advantages of its use
1. Fast & Reliable Field Testing – NARPS does not require concrete dust extractions or laboratory testing, and minimises turnaround and site access time and costs.
2. Ease of Use – NARPS operates by being placed in direct contact with the structure under test, thus removing the need for drilling and dust removal, while maintaining structural integrity and removing the need for laboratory analysis.
3. Minimised disruption – because the NARPS sensor-head only needs to be in contact with the surface under test for a short time, it causes minimal disruption. This is extremely important when testing in difficult, hard to reach locations where high traffic volumes are present.
4. Flexibility – the core technology can be used on a wide range of concrete structures
This technology can apply to any structure which uses reinforced concrete, with a particular emphasis on:
• Bridges – NARPS could find applications in the construction of concrete structures including in-situ and precast bridges, as well as the in-situ maintenance and inspection sector.
• Pre-Cast structures – applications include buildings, landscaping, storage tanks, culverts, 3-sided structures, highway and trafficbarriers, retaining walls, etc.
• Piers – applications include water interacting structures due to their placement in harsh marine environments which are often completely submerged or saturated with water
Intellectual property status
An initial patent application for “Detection System and Method in Concrete Structures” was filed in 2014 – GB1406000.8.
Current development status
NARPS is at laboratory prototype stage with initial results showing strong correlation between measurements obtained and level of corrosion. State funding has been received to build out a commercial-ready prototype.
Desired business relationship
DIT is currently seeking expressions of interest from companies interested in licensing and developing products based on this technology.
