dc.description.abstract | Application of non-destructive testing methods in defining the mechanical properties of mortar and concrete is continually developing. Self-compacting or self-leveling mortars are already widely applied in construction of new structures. As self-compacting mortars are finding their place in rehabilitation and repair of reinforced concrete structures, it is of high importance to design mixtures with compressive strength and modulus of elasticity compatible with existing concrete. Ten mortar series with variation of component materials (fly ash, recycled concrete aggregate, crushed brick aggregate and crushed brick filler) were the subject of following tests: resonant frequency, ultrasonic pulse velocity and compressive strength of mortar. Dynamic modulus of elasticity was calculated using the first two methods mentioned. Results from resonant frequency measurements were then used for calculating compressive strength of the mixtures through different models developed for ordinary concrete and available in the literature. It was shown that the model proposed by Gardner is closest to describing the behavior of mixtures with different component materials, but would need some corrections in order to be used for these purposes. | en |
