PROBLEM TO BE SOLVED: To obtain lightweight soil cement capable of simply land-forming a ground having excellent strength by adding a cement solidification material to the mixed soil of a vitreous foam acquired by adding a foaming material to vitreous waste-material powder and soil. SOLUTION: A foaming material is added to a vitreous waste-material powder obtained by crushing a glass waste material such as bottle glass, flat glass or the like and thermally treated, and crushed stone-shaped vitreous foams 1, 1 are acquired. Cement solidification materials 3, 3 are added to mixed soil, in which the vitreous foams 1 are mixed with soil 2, 2, and lightweight soil cement 13 is manufactured. Sandy soil or loamy soil is preferable as soil 2, and a material, in which a small amount of pulverized glass powder are blended to coarsely crushed glass powder, is desirable as the vitreous waste material powder. When the lightweight soil cement 13 is spread all over and rolled and compacted, a ground having excellent strength can be land-formed.
