    • PROBLEM TO BE SOLVED: To increase the bending strength of an SiO2 -CaO-based solidified material by treating a mixture of a CaO-based substance with an MgO-based substance and an SiO2 -based material in a specific proportion with an autoclave and solidifying the treated mixture. SOLUTION: This CaO-MgO-SiO2 -based solidified material is obtained by treating a mixture containing a CaO-based material, an MgO-based material and an SiO2 -based material with an autoclave and solidifying the mixture. The solidified material has 3.7-50% (C+M) and >=0.3C/(C+M) when the sum total weight content of the three of CaO, MgO and SiO2 in the solidifying raw material is 100%; the weight percentage of the CaO accounting for the total 100% of the three is C% and the weight percentage of the MgO therein is M%. Since the SiO2 -based material is more inexpensive than the CaO-based substance and the MgO-based substance, the amount of the SiO2 -based substance is preferably increased as much as possible. The resultant solidified material, as necessary, is dried under suitable conditions and utilized as various construction and civil engineering materials, etc. The solidified material is especially preferably used as an interlocking block.
