  • Chloride Consolidation and Penetration

    This experimental research was to investigate the chloride penetration and consolidation behavior of OPC and coal gangue added cement. By comparing the results of two kinds of cement, results showed that the chloride consolidation of gangue added cement is higher than OPC. The chloride consolidation increased with more gangue added. The coal gangue is helpful to impede the chloride ingress

  • Performance of Coal Gangue-Based Cemented

    Coal gangue-based cemented backfill material (CGCBM) is developed for backfilling the goaf in coal mines. As fresh CGCBM slurry is generally transported into underground openings through a pipeline, and after hardening, it plays the role of supporting the overlying strata. The fluidity, stability, and mechanical (compressive strength) of CGCBM become the most important properties.

  • The Dosage of Superplasticizer in Cemented Coal

    Cement-fly ash paste surrounds fine gangue particles and forms a lubricating layer between them, which makes up the middle unit of slurry flow and mortar. The flowability of mortar depends on the space between fine gangue particles (defined as fine gangue space) and the fluidity of cement-fly ash paste. The better the fluidity of cement-fly ash paste, the lower the friction on fine gangue

  • Preparation and Reaction Mechanism

    Kramar et al. found that alkali-activated slag mortar (180 mm) possessed a greater fluidity than fly ash mortar (152 mm) and metakaolin mortar (166 mm) under the same conditions, which was mainly attributed to the following reasons: Slag had no regular crystals, thereby having a larger surface area than coal gangue. In addition, slag required less water than coal gangue. Therefore, the

  • The Differences Between Cement, Concrete, and

    Mortar is yet another building material composed of cement, which in this case is mixed with fine sands and water, with lime added to improve the durability of the product. Adding water to this mix activates the cement so that it hardens, or cures, just as with concrete. Mortar is not as strong as concrete and typically is not used as a sole building material. Rather, is it the "glue" that
