Sensicon investigate the benefits of self-healing concrete

Sensor City based Sensicon combine low carbon materials, smart thinking and digital technology to form sustainable and environmentally friendly ways of building in the UK.

In collaboration with JP Concrete and the University of Liverpool, Sensicon are now investigating the use of bio-concrete to create more resilient and environmentally friendly precast walls for building retaining structures and infrastructure projects.

This nature based technical solution can be applied across environmental, infrastructure and industry applications, minimising the carbon footprint when manufacturing reinforced concrete.

Additionally, the process aims to replace ordinary concrete with bio-concrete, preventing the formation of cracks, and reduce the cost of replacing existing structural walls that are deteriorating.

Traditionally, when cracks appear in concrete structures it leads to corrosion in reinforcement. The self-healing concrete however uses multiplying bacteria in the concrete mix to begin producing limestone when in contact with water. The limestone then autonomously repairs cracks and prevents leakage, protecting the reinforcement.
