Experimental Study on Aerated Concrete Produced by Iron Tailings
The non-autoclaved aerated concrete block with greater than 7.5Mpa compressive strength is produced by using iron tailings, lime, aluminum powder, caustic alkali, water, cement and gypsum in the laboratory after the experimental study on the property of iron tailings produced by Anshan Iron and Steel Group. The optimal mix proportion is finally determined by adopting orthogonal experimental method, the evaluating indicator is compressive strength. Aerated concrete block that is made from iron tailing is trial produced according to the national standards, and then its strength is determined by sample examination.
