Use of gasification residues in aerated autoclaved concrete
Adding gasification residue to aerated autoclaved concrete is a viable method for its use. This is an economically and ecologically suitable method for reuse rather than landfill disposal of the waste. There were no detrimental affects when the residue was substituted for aggregate in up to 10% in laboratory tests.Web
