This document presents the results of a study investigating the performance of self-compacting concrete containing furnace slag. Self-compacting concrete has advantages in technical, economic and environmental areas. The study aims to replace furnace slag for fine aggregates in self-compacting concrete mixtures. Experimental tests were conducted on concrete cubes, cylinders and prisms with furnace slag replacements ranging from 0-20% to determine the effects on mechanical properties. The results showed that concrete achieves optimal strength at a particular furnace slag replacement percentage, beyond which strength is reduced. Finite element analysis was also used to model and analyze reinforced concrete columns.
