Preparation of a Multi Media Ceramsite Containing Magnetic Powder

Abstract:

Recently, using biological ceramsite to treat wastewater has received wide attention. In this study, use of fly ash, cement, calcium oxide, gypsum, expanded perlite as main components, magnetic powder and sodium bicarbonate as complex additive and sodium silicate solution as binder, a novel biological ceramsite was developed by steam curing method. Density, piled density, apparent density and void fraction of the biological ceramsite were tested. The optimal percentage of main components was obtained through the orthogonal experiments. In addition, the main affecting factors were also analyzed on the properties of the biological ceramsite. The results showed that the optimal percentage of magnetic powder, sodium bicarbonate, cement and expanded perlite was 10%, 10%, 10% and 5% respectively.The analysis of the results disclosed that the affecting factors of the density, the piled density, the apparent density and the void fraction were the expanded perlite, magnetic powder, cement (and magnetic powder), sodium bicarbonate, respectively.
