Sažetak:
The enormous costs and safety issues associated with corrosion of steel in concrete have resulted in the development of a wide range of new technologies and materials to increase the durability of reinforced concrete structures and their repairs. One of these methods is the use of certain types of stainless steel, which are resistant to corrosion in concrete environment even when the concrete is highly contaminated with chlorides, as substitution of part or all reinforcement in concrete. The use of stainless steel as a replacement for carbon steel reinforcement has been limited to vital structures exposed to aggressive environments by concerns over the increase in initial construction costs. Recent results indicate that some alloy steels under certain conditions behave significantly better than ordinarily used black steel reinforcement. Since the price of alloy steel reinforcement is comparable to the price of normal black steel reinforcement, the idea of using alloy steel as reinforcement is economically justified. In this paper the experimental program that will be used to evaluate corrosion behaviour of different types of alloy steel when used as reinforcement in concrete is presented. Results of so far performed corrosion testing of different types of alloy steel in alkaline media are presented as well. The aim of the research is to evaluate the influence of chloride ions and carbonation on passivity of alloy steel in alkaline media such as concrete. Corrosion performance and material cost of alloy steel will be compared to black and stainless steel.
