Abstract: The Effects of Sunflower Seed Husk (SSH) as aggregate replacement materials on concrete properties were investigated using different amounts of physical and mechanical properties. Concrete of 300 and 400 dosages was produced by adding various amount of SSH (5, 10, 20 and 30%). The replacement of SSH dramatically reduced the unit weight, compressive strength, splitting tensile strength and freezing-thawing resistance, but it increased the water absorption rate after 28 and 90 days. Its physical and mechanical properties show that concrete produced with SSH has great potential as a low cost lightweight building material.
