Original Abstract
Paper is focused on usage of non-destructive acoustic method Impact-Echo (IE) on concrete samples of different mixtures degraded by high temperature. Diagnostic approaches in the post-fire assessment of concrete construction are in vast majority limited to testing the core bores created in situ. This paper study the possibility of determination of condition of concrete test samples by acoustic method IE. Results from measuring of two different mixtures are presented. Mixture A with coarse aggregate 8/16 mm and mixture B with coarse aggregate 11/22 mm. Results from non-destructive measuring by IE and velocity ultrasound pulse method are compared with destructive tests. A correlation between these tests is observed and discussed.
