Application of Magnetite Mill Tailings and Solvay Distiller Waste in Foamed Concrete In Situ

Abstract:

It is in great request to substitute foamed concrete for organic thermal insulating materials that are inflammable and liberate virulent gases on burning. In current study, felsite powder (powdery magnetite mill tailings) was used as filler and Solvay distiller waste (DW) was used as hardening accelerator for foamed concrete. The results showed that the strength and strength-to-density ratio of foamed concrete in cement-felsite powder system is much higher than those in cement-sand system and cement-lime-sand system. The Solvay distiller waste, suspending agent and polypropylene fiber can improve performances of foamed concrete such as cohesion and strength. DW can reduce shrinkage in forming process of foamed concrete.
