PURPOSE:To obtain the title conditioner which can condition surplus soil in construction, having high water content, to make it suitable for reuse as resources by using a carboxylated water-soluble polymer and lime as constituents. CONSTITUTION:The title conditioner contains a carboxylated water-soluble polymer [e.g. a (meth)acrylamide polymer containing (meth)acrylic acid or its salt] and lime (powdery quick lime or slaked lime) preferably at a weight ratio of (1:2) to (1:250). By using this conditioner, surplus soil of high water content, which has hitherto been difficult to utilize and an object for illegal dumping, can be conditioned in a plant as it is without being dried in the sun so that it can be reused as resources for back filling, etc. |
