We contribute recycle and promotion of environment protection by solidification material corresponding to soil, construction conditions and conditions of a final disposal site.
Surplus Soil Solidification Material
It disposes of them as industrial waste (construction sludge) because evacuation surplus soil that produce by mud shield construction. However, recently, the problem of shortage of final disposal site reveals and it requires promotion of construction material recycling from environmental load reduction. In solidification of mud, materials such as polymer, cement, lime etc. are used alone or in combination after considering soil condition, construction condition, disposal site conditions,etc. Because polymeric solidification material is neutral and has immediate effect, improvement can be seen in just a few seconds after itʼs addition and meaning this material is optimal for conveying mud. However, like the lime and cement it doesnʼt dehydrate after reacting with water, rather it changes the particle structure by water absorption and flocculation action, so the water content ratio does not change. Therefore, in the case of landfill etc. where strength is required, it is necessary to use polymeric solidification material in combination with lime or cement.
