Note: A newer version of this document exists. This document was replaced by 229R-13.

Controlled low-strength material (CLSM) is a self-compacted, cementitious material used primarily as a backfill in place of compacted fill. Many terms are currently used to describe this material, including flowable fill, unshrinkable fill, controlled density fill, flowable mortar, flowable fly ash, fly ash slurry, plastic soil-cement, soil-cement slurry and other various names. This report contains information on applications, material properties, mix proportioning, construction, and quality-control procedures. The intent of this report is to provide basic information on CLSM technology, with emphasis on CLSM material characteristics and advantages over conventional compacted fill.
