Innovations in Controlled Low-Strength Material (Flowable Fill)

Editor(s): Jenny Hitch, Amster Howard, Warren Baas

Get the latest information on Controlled Low-Strength Material (CLSM), including new design procedures, current research, unique project applications, and innovative installation techniques. Also known as flowable fill, CLSM is used in place of compacted backfill or unsuitable native soil with the most common uses as pipe embedment and backfill. It continues to gain acceptance in the construction industry and helps create higher quality products.

Eleven peer-reviewed papers highlight the innovations in technology, test methods and material science that have occurred during the evolution of CLSM. Sections include:

Innovative Ingredients—explores the use of non-traditional ingredients in CLSM and determines their suitability or limitations.

Engineering Property Analysis—covers the engineering properties for certain applications of CLSM and includes papers that utilize existing ASTM test methods as well as explored new methods to measure parameters, such as excavatibility.

Pipeline Applications—addresses some of the issues related to pipeline design since one of the most common uses for CLSM is pipe backfill.

As an added bonus you get five current ASTM standards on CLSM developed by Committee D18 on Soil and Rock.

This new publication is a valuable resource for engineers (civil, geotechnical, structural, and transportation); contractors; salesmen, technical service managers, and quality control managers for the ready-mix, admixture, cement, and fly ash industries; FHA and EPA field engineers; and university professors.
