Sažetak
In this paper ongoing experimental test program is presented. Experiments are being conducted on a larger number of test specimens. Specimens are small-scale models of reinforced concrete beams and slabs and they are exposed to a process of chloride induced steel corrosion. Accelerated steel corrosion is stimulated by NaCl solution spread on the specimens. Specimens are in an environmental chamber under permanent conditions control and they are constantly loaded with an equivalent to the service load causing cracks in the concrete. Mechanical characteristics of materials as well as concrete permeability are tested. Chloride concentration in concrete, corrosion parameters and specimens deformation is periodically measured. Tested characteristics of materials for specimens, procedure of loading and testing of beams and slabs specimens and description of accelerated reinforcement corrosion process in an environmental chamber are presented. This paper gives partially processed experimental results and an analysis of observed appearances so far.
