CIP 17 - Flowable Fill Materials
CIP 17 - Flowable fill MaterialsWHAT is Flowable fill ? Flowable fill is a self-compacting low strength materialwith a Flowable consistency that is used as an economi-cal fill or backfill material as an alternative to compactedgranular fill . Flowable fill is not concrete nor it is used toreplace concrete. Terminology used by ACI Committee229 is Controlled Low Strength material (CLSM). Otherterms used for this material are unshrinkable fill , con-trolled density fill , Flowable mortar or lean-mix terms of its flowability, the slump, as measured forconcrete, is generally greater than 8 inches (200 mm). Itis self-leveling material and can be placed with minimaleffort and does not require vibration or tamping. It hard-ens into a strong material with minimal the broader definition includes Materials with com-pressive strength less than 1200 psi ( MPa), mostapplications use mixtures with strength less than 300 psi( MPa).
1989 AND 2000 How is Flowable Fill Delivered and Placed? CAUTIONS 1. Flowable fill while fluid is a heavy material and during placement will exert a high fluid pressure against any forms, embankment, or
