Luckily, most fire damaged structures can be repaired rather than having to be demolished and reconstructed. This certainly is a positive since it’s the most cost-effective solution. However, there are several things to consider when assessing the extent of the damage. First and foremost, an assessment of the extent of the damage to the concrete and reinforcement as well as their strength is paramount.
There are a number of techniques available to assess the damage to concrete after a fire, including visual inspections, non-destructive testing as well as the removal of samples for testing in a lab. On-site tests include hammer soundings, rebound hammer and ultrasonic pulse velocity (UPV) testing.
It is a general rule of thumb that if concrete is heated above 572’F it has lost most, if not all, of its strength. Color changes occur when the concrete is heated to this temperature, resulting in a red/pink hue. Identifying the boundry of the red/pink hue identifies the limit of damaged concrete. However, it’s important to keep in mind that not all types of aggregate will show this type of coloring and as a result, should always be tested by a physical strength assessment.
There may be benefit in supplementing the normal on-site testing with some non-destructive testing. The rebound test gives a measure of the surface hardness of the concrete. Although, there is no direct relationship between this measurement of surface hardness and strength, an empirical relationship exists. Unfortunately, due to the need for a flat surface to test and as a large number of tests is desirable to reduce the effects of variability, the rebound hammer is not generally suitable for use on spalled surfaces, which is often the case with fire damaged concrete. The UPV test for the estimation of the concrete’s strength is well established but again, there is no fundamental relationship between pulse velocity and strength. Although, an estimation of strength can be obtained by correlation, the UPV method has perhaps a greater potential for comparing known sound concrete with affected concrete.
