Abstract | ||||
THE OBJECTIVE of this study is to investigate the possibility of utilizing bagasse ash to improve the cement immobilization of chromium (VI). It was concluded that the blended cement which contain 15-20% bagasse ash can be used effectively forimmobilization of concentrated waste Cr (VI) solutions (≈13000 ppm Cr (VI)) after being mixed with the blended cement in water to cement ratio of about 30%. The immobilized cement paste will set at about 4hr and gain satisfactory compressive strength of about 450 kg/cm2. The immobilization efficiency ≈ 90% under this conditions. | ||||
