Ultrasound Measurements for the Detection of Disintegration of Concrete Slabs Exposed to Fire
Original language description
The paper presents the application of ultrasound measurements for the determination of structural alterations of concrete exposed to fire. Concrete is evaluated as an incombustible material, class A1, but the high exposure temperature, like in fire, maycause cracks and changes of internal structure. The ultrasound measurement is a nondestructive method. It is possible to measure ultrasound velocity before and after thermal loading. The ultrasound measurement could be used also at building side as to detect structural alterations after a fire or imperfection in concrete elements. Three different concrete mixtures were prepared and tested in this study. The basalt aggregate were used in the reference mixture and in a mixture with addition of polypropylene fibers (PP-fibers). The third concrete was made with light weight aggregates (LWA). The test slabs (dimension 10 x 30 x 1150 mm) were poured and cured in laboratory ambient (22C and 40% RH) for 3 months. Then the slabs were exposed to
