In order to study the effect of fly ash content in cemented paste backfill (CPB) on its anti-sulfate erosion, apparent phenomenon, strength development, and hydration products change law CPB with different under long-term soaking 5% sodium sulfate solution were studied by macrotest microanalysis, addition, mechanism attack was analyzed combining a scanning electron microscope (SEM). The results indicated that environment (FCPB) mainly determined FCPB at times. early stage, formation...
In order to research the influence of high-sulfate mine water on filling paste, macroscopic and microstructural changes paste in sulfate environment were analyzed by uniaxial compression tests, X-ray diffraction (XRD) scanning electron microscope (SEM). The mechanism deterioration cracking was discussed. experimental results show that there are numerous gelling materials specimen during curing period, which can increase strength specimen. After cured soaked solution for less than 90 days,...
In order to study the effects of different concentrations sulfate on strength fly ash‐based coal mine filling paste, using variable control, mechanical analysis, and other means, changes in uniaxial compressive strengths paste blocks soaked sodium solution for durations are studied, their stress‐strain curves discussed. The hydrated products each block analyzed at stages by XRD, results indicate that have after soaking durations. A with a concentration 5% had an activator effect enhanced...
In order to reduce the filling cost and improve coefficient of utilization fly ash in coal mine paste, influence desulfurization gypsum quicklime on setting time uniaxial compressive strength (UCS) paste with large quantity were studied using control variable method, mechanical analysis, other means.The hydration products microstructures corresponding age analyzed by X-ray diffraction (XRD) scanning electron microscopy (SEM), results indicate following: can ash-filling plays an important...
