Assessing Fire-Damaged Concrete

Engineering research at The University of Nottingham, UK and Ningbo, China (UNNC) has found laser scanning is a new and viable structural safety technique to detect the damaging effects of fire on concrete.

It takes temperatures in excess of 300 C in order for the structural integrity of concrete to be affected.

One of the researchers commented,”A comparative analysis of the laser intensity for heated and unheated concrete showed that the recorded intensity values for heated concrete are higher than those of unheated concrete. In fact, the laser intensity values of heated concrete showed a remarkable increase in the concrete exposure temperatures from 250°C to 1,000°C.”

He continued, “Such a correlation between the intensity and the exposure temperature is of cardinal importance in assessing the condition and extent of damage to concrete. This finding implies it could be possible to use laser intensity to detect the state of concrete whether it has been heated or not.”
