05/05/2012 · In this investigation, 15 fly ash replacement caused a reduction in the peak temperature of about 4 to 6°C in the mortar. The setting time of fly ash mixes where 15 and 30% of the cement was replaced with fine fly ashes was faster than that of the control mix. The compressive strength of mortar mixes using finer fly ashes (60F and 90F) was ...
Fly ash and a mixture of alkaline activators namely sodium silie (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 ...
Ash accumulation in the DPF increases with oil consumption and lubricant ash content, as lubricant additives are generally the largest source of ash [2669][2670][1326]. Ash derived from lubricant additives is composed primarily of zinc, calcium, and magnesium in the form of sulfates, phosphates, and oxides [2671][2669][2670][2672].
