“…There is therefore a need to find suitable means of utilizing FA in order to address its environmental challenge. Reported utilization of FA includes as the replacement of clay in bricks [7], in road pavement [8], in waste management [9], in synthesis of zeolite [10] [11], as catalyst for biodiesel production [12] [13] and as fillers in polymers [2] [14].…”

The synergetic effect of calcium carbonate (CC)-fly ash (FA) hybrid filler particles on the mechanical and physical properties of low density polyethylene (LDPE) has been investigated. Low density polyethylene is filled with varying weight percentages of FA and CC using melt casting. Composites are characterized for mechanical, thermal, microstructural and physical properties. Results show that the flexural strength increases with increases in FA content of the hybrid filler. It is evident from the study that to achieve optimum density a certain combination of both fillers need to be used. The optimum combination of CC and FA for a higher density (1.78 g/cm 3 ) is found to be at 20 wt% FA and 30 wt% CC. An increase of 7.27% in micro-hardness over virgin polyethylene is obtained in composites with 10 wt% FA and 40 wt% CC. The presence of higher amount of CC is seen to be detrimental to the crystallinity of composites. X-ray, FTIR and DSC results show that composite with 45 wt% CC and 5 wt% FA exhibits a typical triclinic polyethylene structure indicating that the composite is amorphous in nature. There was the synergy between FA and CC fillers on flexural strength and crystallinity of composite. However, the fillers show the antagonistic effect on energy at peak and micro-hardness.

“…The statistical analysis considered 62 published articles. The experimental factors taken into consideration were temperature, reaction time, Si/Al and solid/liquid ratio . Statistical analysis was carried out to study their influence on the type of zoolite synthesized; subsequently, contrast analysis was carried out to compare the synthesis conditions between the zeolites synthesized using FA (Table ).…”

This work describes the statistical analysis carried out on studies of the synthesis of zeolites using fly ash (FA) and kaolinite and shows the main parameters in the hydrothermal synthesis of eight principal zeolites. The chosen zeolites were faujasite (zeolite X), zeolite A, zeolite P, hydroxysodalite, analcime, chabazite, hydroxycancrintie, and sodalite for FA and kaolinite. The statistical analysis consisted of analysis of variance (ANOVA) of the four principal parameters considered: temperature of synthesis, reaction time, Si/Al ratio of the FA and kaolinite and the solid/liquid ratio in the hydrothermal system. For the use of FA, zeolite P, zeolite X, and hydroxysodalite were the three principal synthesized zeolites in the majority of the studies while zeolite A, zeolite P, and sodalite where the three principal zeolites synthesized when kaolinite was used. In general terms, the use of FA required a low temperature and time of synthesis compared to the use of kaolinite. With regard to the Si/Al ratio, the values were similar in both cases, while the solid/liquid ratio for the use of FA was higher than that for kaolinite. Contrast analysis was carried out showing several differences in the synthesis of the eight types of analyzed zeolites.
