Failure Monitoring of Mechanically Loaded Concrete Blocks by Electromagnetic and Acoustic Emission Methods

Popis výsledku v původním jazyce

Electromagnetic emission and acoustic emission methods are promising methods to study the generation and behavior of cracks. Emission signals appear during crack generation when a solid is exposed to mechanical loading. Our study in this paper is focusedon specially prepared concrete blocks. Four groups of concrete samples with various concrete composition formulas have been prepared for two-channel measurement on our experimental set-up. Concrete blocks from each prepared group were measured for defined loading conditions (especially for linearly increasing uniaxial compression up to the load of 80 kN with the rate of 11 N/s.). The response of concrete specimens to applied mechanical load was continuously monitored by recording electromagnetic and acoustic emission signals. The main aim of our experiment was to determine how the crack generation intensity depends on the aggregate size in tested concrete samples. Our pilot experimental results show (as we expected) that the generated
