Description	This paper is focused on the failure monitoring in cementitious composites under mechanical loading. The aim was to determine how the cracks generation intensity depends on the aggregate size in tested concrete samples. Our diagnostic method is based on the measurement of electromagnetic and acoustic emission signals, which occur when the solid dielectric materials are mechanically stressed. Several groups of concrete samples with various concrete composition formulas have been prepared for our experiment. We made two channel measurements of the concrete samples from each groups for defined loading conditions. This contribution describes our measurement system and also includes the pilot experimental results of the different cementitious specimens during linearly increasing uniaxial compression. From the obtained results can be concluded that the generated cracks intensity is significantly affected by the aggregate amount and size.
