Description

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.

Keywords: aggregates; backfill; compacted fill; controlled density fill; controlled low-strength material; flowable fill; flowable mortar; fly ash; foundation stabilization; low-density material; pipe bedding; plastic soilcement; preformed foam; soil-cement slurry; trench backfill; unshrinkable fill; void filling.
