This thesis deals with the implementation of Ferrocement for strengthening of reinforced concrete beams exposed mainly to flexure. Ferrocement belongs to the group of cement-based composites, and it is defined as micro-reinforced concrete. An effect of flexural strengthening was studied, through application of ferrocement elements (strips) on the tensed side of RC beams. The goal of this research is finding potential of application, feasibility and cost-effectiveness of usage of ferrocement as a material for strengthening of RC structures exposed to flexure. The strengthening procedure, implemented in the thesis, consists of joining the reinforced concrete beam and previously produced ferrocement strip by adhesion, using adhesive epoxy-mortar. The scientific research method was a combination of analytical, experimental and numerical research. Experimental researches were conducted on RC beams strengthened with four types of ferrocement elements, with the accompanying research of non-re...inforced (control) RC beams. Behavior of experimental models under the action of short-term static load causing pure flexure was researched. An analytical formulation of the problem was provided and a numerical non-linear analysis using FEM was performed, and verified by experimentally obtained results. The issues of limit states of strength and serviceability of beams were treated.
