Abstract

Deposits of natural sand, gravel, and stone especially those located close to major urban centers, may get depleted or become costly owing to transportation costs and environmental restrictions. The utilisation of industrial by-products as raw materials need to be carried out rapidly in order to save natural resources become depletes. This research study describes the work carried out in laboratory to identify the potential usage of Electric Arc Furnace Slag (EAFS) or steel slag as coarse aggregate in concrete as well as its compressive strength and its aggregate properties compared with natural aggregates. The developments and innovations of new material system or the emergence of unconventional construction materials need to be carried out because it brings advantages towards environmental problems and future construction industries since it's just being abundant or rarely in used. Several mixes of concrete are designed in order to analyse concrete strength incorporating 10%, 50% and 100% of slag aggregate and compared it with control mix which using 100% of granite aggregate. Accordingly, physical properties and Mechanical properties and accelerated durability test (carbonation depth) for granite and steel slag aggregate were investigated. From the result obtained, the compressive strength of concrete specimen incorporating 100% of steel slag achieved better performance compared with that of natural aggregate concrete for grade 20, 30 and 40 respectively. The mixture with EAFS aggregate presented highest strength result at 28th day. Similarly, some of the physical properties of the EAFS aggregate were better than that of natural aggregate (granite). The steel slag aggregate possesses good physical and mechanical properties and has sufficient stability for use as coarse aggregate in concrete industry in Malaysia.
