fly ash optimization

  • CONCRETE Optimizing the Use of Fly Ash in Concrete

    of the fly ash. Low-calcium fly ashes (< 8% CaO) are invariably produced from anthracite or bituminous coals and are predominantly composed of alumino-silicate glasses with varying amounts of crystalline quartz, mullite, hematite and magnetite.These crystalline phases are essentially inert in concrete and the glass requires a source of alkali or lime (for example, Ca(OH) 2) to react and form

  • Optimization of fly ash concrete mix a solution for

    The optimization of concrete with fly ash carried out using the three parameters i.e. water to binder (W-B) ratio, coarse aggregate to total aggregate (CA-TA) ratio and different percentages of fly ash. These parameters were optimized in the best possible way to obtain desired compressive strength which is useful in the mix design.

  • Process parameter optimization for fly ash stone by

    Materials Research Print version ISSN Optimization of process parameters for fly ash stone was performed via Taguchi's parameter design method. An L 9 OA was used to accommodate four control factors and each with three levels for the experimental plan. Selected process parameters along with their levels were: water /binder ratio (0.42, 0.41, 0.40); fly ash (35, 37, 39%); coarse sand (24

  • Parametric Optimization of Alkali Activated F-Type Flyash

    This stone describes the effects of various optimized parameters on the properties of fly ash based geopolymer concrete, especially the compressive strength, density and workability have been investigated. The effect of various optimized parameters related to alkaline activator such as molar concentration of sodium hydroxide solution in the range of 8M-16M, mass ratio of alkaline liquid to fly

  • Optimization of Alkaline Activator/Fly ASH Ratio on the

    Fly ash and a mixture of alkaline activators namely sodium silicate (Waterglass) and sodium hydroxide (NaOH) solution were used for preparing geopolymer. The aim of this research is to determine the optimum value of the alkaline activator/fly ash ratio. The effect of the oxide molar ratios of SiO2/Al2O3, water content of the alkaline activator and the Waterglass% content were studied for each
