The soil cement used for the cut-off wall is a brittleness material. Therefore, in the case of the soil cement cut-off wall, the problem of the water leak by generation on the shearing surface is feared. As the countermeasure against generating shearing surface, the tire chip mixture soil cement is proposed. In addition, under 10% of tire chip mixture ratio for the tire chip mixture soil cement is proposed as the measures, because the workability decreases as the mixed quantity of the tire chip increases. Then, the strength transformation characteristic of the tire chip mixture soil cement of the tire chip mixture rate under 10% was investigated. As a result, the tire chip mixture soil cement in the tire chip mixture ratio under 10% accompanied an increase at the tire chip mixture rate, strength showed the decreasing tendency, and the destruction strain showed the increasing tendency. Moreover, the improvement of toughness was remarkable in the tire chip mixture rate 5% or more.
