The Construction and Design of Concrete Slabs on Grade

controlled low-strength material (CLSM), or lean concrete sub-base. Generally cement treated and lean concrete sub-bases are 4 to 6 inches thick. A modulus of sub-grade reaction of 400 to 500 psi/inch can be used in calculating the required thickness of floors placed directly on lean concrete and cement treated or roller compacted sub-bases.
