Originální abstrakt

The results of many bending tests of fiber reinforced concrete specimens did not produce a clear answer to the question whether the fibers are activated before the macro-crack. Our diagnostic method is based on the measurement of acoustic emission signals during three-point bending tests of concrete specimens with stress concentrator. Acoustic emission activity measurement could help us to answer the question if the fibers are activated before the macro-crack is able to seen by human eyes. Several groups of concrete samples with various concrete composition formulas have been prepared for our experiment. This contribution describes the prepared concrete composition, measurement system and also includes the experimental results of one concrete samples set.
