Abstract

The decline in the availability of natural aggregates and the high cost of construction materials has necessitated the quest for alternative materials. This study investigates the combined effect of using marble dust (MD) and iron filings (IF) as a partial replacement for fine aggregates (sand) in concrete production. Concrete cubes measuring 150 X 150 X 150 mm3, were cast, using a mix ratio of 1:2:4 and a water/cement ratio of 0.5. The specimens were tested for workability and compressive strength at 0% (control mix), (2.5% IF, 7.5% MD), (5% IF,15% MD), (7.5% IF,22.5% MD), (10% IF,30% MD) replacement of sand (by weight) with IF and MD after curing in water for 28 days. The test results showed that the best gain in compressive strength was with (2.5% IF, 7.5% MD) replacement. At this replacement level, the compressive strength exhibited a 9.6% decrease compared to control cube strength. Regardless of the observed decline in the concrete strength produced, the concrete strength at 28days still relate favorably well with the control cube, and also meet the strength requirement of a good structural concrete.
