Abstract/Summary
In this study, compression tests were performed on three different mix designs of concrete to evaluate the effects of iron filings as an admixture to concrete. The first mix design served as the control mix, being the variable that the other two mixes will be based off. The second mix design was the same as the first mix design, but with an added 12 ounces of iron filings. The third mix design was, again, the same as the first mix design, but with an added 24 ounces of iron filings doubling that of the second mix design. The objective of testing these mix designs containing iron filings against the control mix was to evaluate a potential increase or decrease in compressive strength. Six (6) 4” x 8” test cylinders were produced for each mix design to allow for multiple compressive strength tests. These tests were performed after a 7-day cure and a 21-day cure, with three cylinders of each mix tested after each cure time period. The results of the tests revealed that there was an overall average of 3% decrease in compressive strength compared to the control mix. It would seem that iron filings are not suitable as an admixture to concrete. However, due to the limited scope and testing, further testing would be necessary to accurately evaluate the effects of iron filings as an admixture to concrete.
