May 01, 1991 · Controlled low-strength material (CLSM) is a backfill product that flows as easily as thick pancake batter and is self-leveling. Its consistency is like that of a slurry or lean grout, yet several hours after placement the material is hard enough to support traffic loads without settling. Guidelines for CLSM as bedding - NCPIstrength. Flowability Flowability measurement shall be an 8 inch +/- 1 inch spread diameter using a three (3) inch diameter by six (6) inch long cylinder and shall meet the requirements of ASTM D 6103 Standard Test Method for Flow Consistency of Controlled Low Strength Material (CLSM).

This could be almost entirely avoided by knowledgeable concrete technical personnel. The course will cover the analysis of strength test results to identify causes for low strength problems including technician MASONRY MORTAR TESTING - NCMACompressive Strength Testing of Field-Prepared Mortar. Compressive strength is one of the most commonly tested properties of field mortar. The test, described in ASTM C780, provides an indication of mortar consistency during construction, not as an indication of the compressive strength of the masonry, or even of the mortar in the wall. Compressive strength test results should be compared on a
Permeability Study Specification for Controlled Low Strength Materials (CLSM) The permeability in the existing concrete structure is an essential and important step for the definition of its durability, performance, and lifetime. Permeability regulates the speed of aggressive water penetration inside the concrete, besides Report on Controlled Low-Strength Materials9.7Quality control, p. 19 CHAPteR 10ReFeRenCes, p. 19 CHAPteR 1IntRoDUCtIon Controlled low-strength material (CLSM) is a self-consol-idating cementitious material used primarily as a backfill as an alternative to compacted fill.
