Quantitative Research on Strength Characteristics of Phosphogypsum Consolidation Materials

Article Preview

Abstract:

To established an strength factor model of PCM (Phosphogypsum Consolidation Materials) innovatively based on tests and mathematical methods of factor analysis whose influences to strength performance were quantitative analyzed. To build a mechanism schematic diagram about the mineral formation of PCM which visually analyzed its internal mineral formation mechanism. Making use of ESEM (Environmental Scanning Electron Microscope), the micro mineral structures about three typical kinds of PCM in different gray sand ratios were compared and analyzed, and focused on the micro quantitative analysis on the C-S-H gel in order to elaborate the relevance between microscopic mechanism and strength mathematical factor model.
