Abstract (300 words maximum)
Some industrial waste materials pose a problem to the environment in terms of treatment and disposal when they become a management burden for manufacturers and producers. Rather than being allowed to populate landfills, these waste materials can be recycled and reused as construction components in place of raw materials. This study will explore the use of locally recycled scrap metal waste byproduct (slag) in cement concrete and evaluate the resulting physical and engineering properties. The optimized use of scrap metal slag in cement concrete mix will help in waste management disposal costs and reduce the cost of raw materials for construction. A laboratory investigation will be conducted with steel slag replacing certain percentages (5%, 10%, 15%, and 20%) of fine aggregates by weight in cement concrete mixtures. Tests will primarily focus on evaluation of concrete workability, compressive strength, and surface resistivity. Control samples will be prepared and tested along with each waste material sample. Compressive strength and surface resistivity will be compared at curing periods of 7, 14, and 28 days. The goal of the study is to recommend an optimal ratio of recycled waste slags with which to replace fine aggregate in concrete mixtures to maximize environmental and economic benefit while avoiding unacceptable sacrifice to concrete strength or workability. It is expected that a certain replacement level of fine aggregate with waste steel slags will provide the same or greater compressive strength and similar workability compared to the control. Surface resistivity is not expected to show significant change with this replacement.
