Original Abstract

The present paper deals with the use of Impact-echo acoustic method to test cement-based mortar composites degraded at high temperatures. The specimens were prepared by using a type CEM I Portland cement and siliceous sand, as well as by substituting 25% of sand with shredded automobile tires and by adding acrylic polymer binder (20% w/w to cement mass). The samples were were subjected to high-temperature treatment in the temperature range of 200-400 st.C. The acoustic results confirmed the differences in the structure of mortar specimens. The addition of rubber aggregates in H2 and H3 specimens resulted in lower frequencies compared to H1 specimen. It was also observed the dropping down of the frequencies for the temperatures between 200-300 st.C, indicating that the effect of heat treatment was mitigated when the acrylic binder was added.
