Steel slag stone can be used as a substitute for coarse aggregate in concrete. In this study, the performance of steel slag concrete (SSC) in the wall brick structure was analyzed. The specimens with a steel slag replacement rate of 0%, 20%, 25%, 30%, 35%, 40%, 45%, and 50% were designed, and the slump, stability, and carbonation resistance were tested. The results showed that the slump decreased with the increase of the replacement rate of steel slag stone. At the 60th min, the slump of SSC50 was 74 mm, which was 25.25% smaller than SSC00. When the replacement rate was more than 30%, cracks or fractures appeared, and the stability was destroyed. Twenty-eight days after the carbonation experiment, with the increase of the replacement rate, the carbonation resistance of the specimen decreased, and the performance was best when the replacement rate was 25%. The experimental results show that the performance of SSC is the best when the replacement rate of steel slag stone is 25%, which can be further promoted and applied in practice.

The western embankment of the Żerań Canal is an area of exceptional natural, cultural and recreational qualities. This site is also the location of the planned construction of a high pressure gas pipeline supplying Żerań Power Plant, which is a strategic undertaking for the north-eastern Warsaw. The study done at the Department of Landscape Architecture of the WULS-SGGW was aimed at determining values of natural and landscape resources and elaboration of the concept of site’s new development after construction of the gas pipeline.
