Abstract
The high cost of construction materials has necessitated the quest for alternative materials. This project investigates the effect of using granite dust (GD) and iron filings (IF) as a partial replacement for fine aggregates [sand] in concrete production. A total number of 36 cubes 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,10% GD), (5% IF,20% GD), (7.5% IF,30% GD), (10% IF,30% GD), replacement of sand (by weight) with iron filings(IF) and granite dust (GD) after curing in water for 28 days. The test results showed that the best gain in compressive strength was with (2.5% IF,10% GD), replacement. At this replacement level, the compressive strength increased by 16.8% compared to control. The study recommends that iron filings and granite dust can be used in concrete production as this would lead to improved environmental waste management and profitable utilization of industrial wastes.
