Original Abstract

The use of impact-echo acoustic method to test cement-based mortar composites modified with rubber aggregates and EVA polymer binder and degraded at high temperatures was studied. 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 EVA polymer binder (10% w/w to cement mass). The specimens were subjected to high temperatures (200-400 degrees of Celsius). The results of non-destructive testing confirmed the different structure of mortar specimens. The partial substitution of sand with rubber aggregates led to absorption of lower frequencies as compared to the reference specimens. A significant decrease of the absorbed freaThe use of impact-echo acoustic method to test cement-based mortar composites modified with rubber aggregates and EVA polymer binder and degraded at high temperatures was studied.

The partial substitution of sand with rubber aggregates led to absorption of lower frequencies as compared to the reference specimens. A significant decrease of the absorbed frequencies was observed, depending on temperature. The largest decrease occurred after the specimens exposure at 200-300 degrees of Celsius.
