Abstract: Controlled low-strength material (CLSM) is a self-compacted, cementitious material used primarily as backfill in lieu of compacted fill. It is also known as flowable fill, unshrinkable fill, controlled density fill, and flowable mortar. ACI 229R defines it as materials that result in a compressive strength of 8.3MPa or less at 28 days. CLSM is generally used in backfills, structural fills, conduit bedding, erosion control, void filling, etc.
