CLSM Topic - American Concrete Institute
Jul 1, 2022 · A controlled low-strength material (CLSM) is a self-consolidating, cementing material used primarily as a backfill as an alternative to compacted fill. Many terms have been used to describe this material, including flowable fill, unshrinkable fill, controlled density fill, flowable mortar, plastic soil-cement, and soil-cement slurry; however ...
an alternative to compacted fill. Terms used to describe this material include flowable fill, controlled density fill, flow-able mortar, plastic soil-cement, and soil-cement slurry. CLSM is a mixture intended to result in a compressive strength of 1200 psi (8.3 MPa) or less. Most CLSM applica-tions require unconfined compressive strengths of ...
Definition of controlled low-strength material (CLSM)
Several terms have been used to describe this material, including flowable fill, unshrinkable fill, controlled density fill, flowable mortar, plastic soil-cement, and soil-cement slurry; however, the correct terminology is controlled low-strength material. CLSM is intended to result in a compressive strength of 1200 psi (8.3 MPa) or less.

ACI PRC-229R-13(22) Report on Controlled Low-Strength …
Controlled low-strength material (CLSM) is a self-consolidating cementitious material used primarily as a backfill as an alternative to compacted fill. This report contains information on applications; materials; properties; proportioning; mixing, transporting, and placing; quality control; and low-density CLSM using preformed foam.
Optimization of Flowable Fill Mix Proportions - American Concrete …
Jun 1, 1994 · The effect of mix proportions on the compressive strength of flowable fill is investigated in this study. Flowable fill, composed of Type I cement, Class C fly ash, sand, and water, meets the requirements of ACI Committee 229 as a controlled low-strength material (CLSM) if the 28-day compressive strength is 1200 psi (8.3 MPa) or less.
fill—material placed to bring grade or subgrade to the desired elevation. flowable fill—self-consolidating cementitious material used primarily as a backfill in place of compacted fill. foundation walls—structural members of a foundation that transmit loads to the footing or directly to the subgrade.
