Abstract：As the main product of the fly ash aerated concrete,the volume changes of Tobey Mullite Crystal has a certain effect on the intensity,dry density and thermal insulation property. This paper calculated the volume ratio of crystal and colloid in the two kinds of concrete through analyzing and processing the BSE image of the common ash aerated concrete and ash aerated concrete with glazed hollow bead and found that the colloid of ash aerated concrete with glazed hollow bead is 1.5 times as that of common aerated concrete. With SEM analysis,the Tobey mullite crystal of the modified aerated concrete becomes smaller and the opening distribution is uniform so as to improve its thermal insulation property. The analysis results explained the modification mechanism of the glazed hollow bead to fly ash concrete in microcosmic view,and the imaging process method provides a scien-tific basis for the quantitative analysis of hydration products.
