sunflower barite as aggregate in concrete

Properties of Heavy Concrete Made with Barite

Barite aggregate behaves in concrete similarly to an ordinary crushed aggregate such as limestone or basalt, and no special problems were encountered in selecting and proportioning the constituents of the concretes. Exceptionally high compressive strengths were developed by conventional barite concrete.

Sunflower seed waste as lightweight aggregate in

2013-1-1  Sunflower seed waste as lightweight aggregate in concrete production 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.
