Effect of iron powder on strength of binary blended concrete

Abstract

The by-products generated from milling industries are iron powders which are harmful resources to human health since they are in the air and can be straightforwardly breathe in. To prevail over this setback we have to dispose the iron powder safely without any environmental hazards. As a result, consumption on iron powder in the concrete has been developed. This study made an attempt to make utilize iron powder waste as a part substitution of Portland cement in M25 grade concrete mix by the volume of fraction in the range of 0%, 1%, 2%, 3% and 4%. The compressive strength test was conducted for the various mix proportions and the achieved strength properties were compared with those of conventional concrete after 28 days. However, the effect of iron powder with 2% partial replacement of cement exhibit an maximum improvement in compressive strength of about 29.80% when compared to that of conventional concrete.
