PROBLEM TO BE SOLVED: To provide a self-collapse type solidified product which is a soil-solidified product, enabling it to self-collapse after being used, and to control the time of being collapsed. SOLUTION: The self-collapse type solidified product is characterized by containing a delay type expandable material having a mildly expanding property in the solidified product obtained by solidifying soil with a solidifying material composed mainly of light burned magnesia. A raw material containing the solidifying material composed mainly of light burned magnesia, soil, the delay type expandable material having the mildly expanding property, and optionally compounded aggregates and an admixture, is mixed with water followed by solidifying the resultant mixture, Wherein calcined magnesia baked at a high temperature of 1,200°C or higher, is contained as the delay type expandable material.
