ABSTRACT
The following is a summary of the basic properties of lean treated soil and ground, where sandy soil is used as the parent material . But the following properties are based on past test data, and there is a possibility that exceptional properties are encountered according to the type of soil used. . Unconfined compression properties 1 . The unconfined compressive strength varies according to the type of stabilizer added and increases as the percentage added and the dry density rise. 2 . The unconfined compressive strength varies according to the curing temperature and increases with the age . 3 . The increase in the strength varies according to the type of parent material. 4 . The failure strain falls within a range from 0 .5% to 2% regardless of the type of parent material . . Triaxial compression properties 1 . The stress - strain relationship tends to be similar regardless of the parent material . 2 . The principle of effective stress is applicable and failure criteria is established regardless of drainage conditions. 3. The angle of shear resistance of the treated soil is almost equal to that of the untreated soil, but the cohesion of the treated soil is higher. Therefore, the treated soil has the properties of a c -¢ material. 4. The brittleness of the treated soil varies according to the type of parent material. 5 . The unconfined compressive strength of the treated soil is almost equal to the
6. If the angle of shear resistance ((Pct) of the untreated soil and the unconfined compressive strength (qud) of the treated soil are obtained by test, it is possible to estimate the shear strength of the treated soil.
