A prototype self-healing concrete is going to be trialled by the UK contractor Costain.
The company is going to invest £600,000 (€709,000) into the project, which will attempt to develop an inbuilt concrete immune system able to repair cracks and wounds.
Scientists are planning to add special bacteria to the concrete, and this is contained within protective microcapsules, which will come to life as soon as water enters a crack. They will then produce limestone deposits, which will plug cracks in the
