THE BEHAVIOR OF MORTAR AFTER ADDING IRON WASTE

Abstract

The need for exceeding the strength of construction material with low cost material is the aim of this work. Iron waste was used to replace the sand in (10, 20, and 30%) by weight .three particle sizes (75,100,150 µm) were chosen for iron filling to reveal the most effective particle size. The results showed the lowest density were obtained at 100 µm particle size and 30% by weight of iron filling. The best water absorption was obtained at 100 µm particle size and 10% by weight of iron filling. The highest thermal diffusivity was obtained at 100 µm particle size and 20% by weight of iron filling. The best thermal conductivity were obtained at 100 and 150 µm particle size and 30% by weight of iron filling and The best compressive strength were obtained at 75 µm particle size and 20% by weight of iron filling. For all samples containing iron filling better properties were obtained comparing with control sample.
