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 300 psi (2.1 MPa) or less. Long-term strengths (90 to 180 days) should be targeted to be less than 100 psi (0.7 MPa) for excavation with hand tools. Lower-strength requirements are Strength Material (CLSM) to Determine Suitability for Load Application D6026 Practice for Using SigniÞcant Digits in Geotechnical Data D6103 Test Method for Flow Consistency of Controlled Low Strength Material (CLSM) 3.

Scope. Controlled Low Strength Material (CLSM), also known as flowable fill, is a versatile material used in construction for various applications such as backfilling, trench filling, and void filling.
The methods for capping CLSM compressive strength specimens are inappropriate for excavatable CLSM cylinders due to their lower stress levels. This paper presents a new capping system for CLSM and compares it logistically and statistically to capping methods approved by the American Society for Testing and Materials (ASTM) for flowable fill .3.1 Controlled Low Strength Material, (CLSM) - A self-leveling and self-compacting, cementitious material with an unconfined compressive strength of 1,200 psi or less. R3.1 Controlled Low Strength Material, (CLSM) While the upper limit on compressive strength is indicated as 1200psi, most CLSM applications require strengths less than 300psi.
