Abstract

FAs and BAs indicated different chemical compositions and physical properties. Leaching of Pb in FAl and Cu in FA2 were 33.2mg/L and 5.92mg/L, these were high concentration above 30 and 2 times respectively in compared to permit level. Leaching of Hg and Cr were about 1/2 of permit level. When diatom was complexly mixed with portland cement, the 28 days compressive strength of mortar with FA2 was similar with that of control mortar. Furtherfore, leaching of heavy metal ions like as Pb, Cu, Hg, Cr was highly reduced.
