Paper Title:
Changing Morphology and Crystal Structure in Ettringite by Trivalent Chromium
  Abstract

Recently, solidification processing by cement material of waste that isn’t only increasing but also study is now in progress. Ettringite(Ca6[Al(OH)6]2(SO4)3•26H2O), which is a hydration product of calcium aluminate minerals is highly effective at immobilizing heavy metallic ions through a substitution mechanism. An aqueous solution containing calcium hydroxide, aluminum sulfate, and CrCl3(trivalent chromium) was subjected to irradiate by ultrasonic irradiation under atmospheric pressure to investigate its effect on the synthesis of Cr(III)-ettringite. The verified XRD (100) peak tended to shift to the left and changed morphology as CrCl3 input.
