Abstract

 The application of bamboo charcoal to cement soil stabilization was investigated in present study. A series of the unconfirmed compression tests was performed on cement-treated soil with bamboo charcoal to clarify the improvement effects. Both normal Portland cement and Blast-furnace Slag cement B were used in these experiments. In addition, Japanese leaching tests No. 46 and a tank leaching tests were conducted to evaluate the effects of bamboo charcoal on leaching characteristics of hexavalent chromium (Cr(VI)) contained in the cement-treated soil. As a result, the unconfirmed compression strength of the cement-treated soil mixing with bamboo charcoal increased remarkably. For each leaching tests, it was indicated that the leaching amount of Cr(VI) was inhibited to some extent due to mixture of the bamboo charcoal in cement cement-treated soil. Moreover, it was found that the unconfirmed compression strength of the cement-treated soil mixing with bamboo charcoal didn't decrease under submerged curing for a long term.
