Abstract
In the paper the results of experimental studies performed on compressed concrete elements strengthened with composite fabric of FRCM (Fibre Reinforced Cementitious Matrix) technology are presented. In the studies the influence of temperature, the number of composite fabric layers and the length of ending overlap on the value and distribution of circumferential limit strains was analyzed.
