Figure 1 shows the powder forms of POFA and FA. The POFA and FA particles sieved through 45 μm have been used for both XRF and the particle size distribution tests. The chemical compounds of POFA and FA were determined using PANalytical X-ray fluorescence (XRF) machine through Omnian analysis. The particle size distribution was done by particle size analyzer through polydisperse analysis. The test results on X-ray fluorescence (XRF) for chemical composition and particle size distribution of POFA and FA are shown in Figure 2 and Table 1.
