Treść
Self compacting concretes (SCCs) modified by different volumes of granulated imperial smelting process (ISP) slag were tested during the research program. Granulated ISP slag was used as a replacement for natural sand. Mechanical properties of such SCCs are already known, but their durability and possible life span of structures made out of them need to be studied further. The conducted tests were focused on chloride ions infiltration into SCCs. The tests were planned in such a way that the achieved results would allow to use a theoretical diffusion model proposed by Szweda and Zybura. The model was verified by a comparison with the results acquired in a real diffusion. Finally, the forecast durability of concrete structures made out of tested SCCs was calculated. The foreseen life span of the structures was differentiated due to thickness of concrete coating of rebars. The proposed approach to SCC with ISP enables reliable prediction of its durability over time and precise technical life span of the structure made out of it. The study proved that replacing sand by ISP slag, even for small ratios, is counterproductive from the durability point of view. It can become feasible, only if an environmental impact study demonstrates it as a very good solution from that point of view.
