PROBLEM TO BE SOLVED: To provide a cement-solidified soil composition which can be suitably used for temporary soil improvement and as a substitute for ballasting in the execution of construction work, which is excellent in fluidity during construction, and which can form solidified matter with sufficient strength. SOLUTION: The cement-solidified soil composition contains silty soil, sandy soil, concrete-crushed powder, Portland cement, water, and a surface-active agent. Preferably, the mixing ratio of the amount of the concrete-crushed powder to the total amount of the silty soil and the sandy soil, which is 100 pts.mass, is in the range of >40 pts.mass and≤90 pts.mass; and the 1.0-1.5 pts.mass water, the 2.5-4.5 pts.mass mixture of the silty soil, the sandy soil and the concrete-crushed powder, and the 0.0002-0.02 pt.mass surface-active agent is contained with respect to the 1 pt.mass Portland cement.
