| Zusammenfassung: | This study aimed to
determine the effect of using nickel slag as an alternative aggregate for
high-performance concrete. To achieve the aim, nickel slag aggregate with
particle sizes of 0/5 mm and 10/20 mm was considered, using X-ray Diffraction
(XRD) to analyze the compounds and minerals contained in the slag content. The
investigation incorporated up to 20% Ground Granulated Blast-furnace Slag
(GGBFS) as a cement substitute, while systematically replacing natural
aggregate with nickel slag at a varying proportions of 0%, 20%, 40%, 60%, 80%,
and 100%. The experimental result showed that Mix 2 combination achieved the
highest compressive strength of 69.43 MPa. This outcome exceeded the reference
concrete by 11.56% and fulfilled the classification of high-performance
concrete. Additionally, XRD testing of Mix 2 samples identified the dominant
compounds as C6H6O2, (Fe, Mg)SiO3,
and SiO2. The results signified the promising potential of using
nickel slag aggregate in concrete production, suggesting significant economic
benefit for the construction industry. The outcome of this study could
contribute to the growth of construction industry and reassure stakeholders
about the financial viability of the project. Finally, this potential for
high-performance concrete using nickel slag aggregate would create more
opportunities for the future of construction industry. |
