Assessing concrete strength in fire-damaged structures
Julia Wróblewska , Robert Kowalski
AbstractThe paper presents a review of concrete assessment methods: laboratory and in situ (non-destructive andsemi-destructive tests) in application to reinforced concrete structures after fire. One of the most impor-tant phenomena affecting the load-bearing capacity of these structures is the reduction in concretestrength at high temperature and after cooling. Traditional test methods, commonly used in normal con-ditions (e.g. destructive test on core specimens), usually do not take into account the non-uniformity ofconcrete after a fire. Therefore, other methods are proposed to determine the depth of the damaged con-crete in the external layers of a given structural member.
