【 摘 要 】

The goal of this study is to assess the opportunity of utilizing waste iron filings in altered fractions as a fine aggregate replacement to produce the reactive powder concrete. Four different fractions of waste iron filing were adopted to reactive powder concrete mixture to measure the difference, which may be achieved in the strengths of the reactive powder concrete. In order to accomplish the aim of the investigation, compressive strength, and direct tensile strength were executed to determine the effect of iron filings on the strength of reactive powder concrete. Consistent with the experimental results, it can be stated that higher fraction of waste iron filings is more effective than the other percentages in both compressive and direct tensile strength because it acquires the maximum strength properties in the shortest duration. The increasing of the compressive strength and the direct tensile strength at 28 days for 30 % of the irons filings was 30.3% and 31.8% correspondingly.
