A new way of testing concrete strength has been trialled in London by contractors Laing O’Rourke and Costain.
The pair have used the Strength Monitoring Using Thermal Imaging (SMUTI) technique at the Bond Street station upgrade (BSSU) on behalf of London Underground.
The new technique was created by Dr Benoit Jones from Cambridge University and uses a thermal imaging camera to track the temperature of concrete as it is sprayed to form the tunnel lining. Knowing this temperature history enables the engineers to calculate the amount of hydration that has taken place in the concrete, and hence its strength.
