PROBLEM TO BE SOLVED: To provide an underfloor structural block body and its forming method which can be solidified on the job site, offering excellent moisture absorbing characteristics as a structural body, a small specific gravity and an appropriate strength and, further, permitting its disintegration relatively easily thereby returning it to the soil after the use. SOLUTION: This underfloor structural block body can be made by mixing a 5 to 15 pts.wt. of silt of pit sand, a 15 to 30 pts.wt. of portland cement as an inorganic solidifier and a 0.1 to 0.5 pt.wt. of a nonionic surface active agent all together to a 100 pts.wt. of construction surplus dry black soils with diameters of 0.4 to 0.6 mmϕas the main component; and the mixture is formed and solidified in the same forming state by spraying water to the mixture to be formed thereby giving both the moisture absorbing and effluent properties after the solidification.
