Abstract

Nowadays prefabricated elements are typically made of highstrength concrete. In case of fire load, in addition to chemical and physical changes, spalling (detachment of layers) of the concrete surface may occur. This is especially true for the high-strength concrete. Based on our previous examinations we stated that computed tomography (CT) provides a good opportunity to test the fire-damaged buildings. However, the question is whether this method can be applied even if spalling of the concrete surface is caused by fire. Fire load tests were carried out on small elements (concrete cubes and blocks) and on full-scale wall panels, then results of these tests were compared. Beside the CT tests, laboratory tests were also carried out. Results of the tests were analysed and compared and by this we validated the correctness and applicability of the CT examinations.
