Abstract

This study comparatively investigated the strength characteristics and workability performance of partial replacement of natural fine aggregate with waste glass particles and iron filings in concrete production. Fine aggregate was replaced with 0%, 5%, 10%, 15%, 20%, and 25% of waste glass particles and iron filings respectively at a water-cement ratio of 0.55. The result indicated that an increase in percentage replacement of iron filings reduced the slump value and workability of the concrete, while the increase in the percentage content of glass particles increased its slump value and workability. The result showed that concrete with 20% replacement of sand by iron filing and waste glass particles attained the optimum strength. Furthermore, concrete samples containing glass particles exhibited a steady increase in flexural strength at all replacement levels. The use of iron filings and glass particles in the production of concrete will enhance preservation of natural resources and waste management.
