Test Method Title

Standard Test Method for Preparation and Testing of Controlled Low Strength Material (CLSM) Test Cylinders

Reference Number

ASTM D4832

Material

CLSM

Test Property

Preparation and Testing of Controlled Low Strength Material (CLSM) Test Cylinders

Description of Test

Concrete is sampled in accordance with ASTM C 5971. Concrete is poured into curing molds without rodding. Each mold is covered to protect against moisture loss, and carefully placed in a protected area. Cylinders cast and cured in the field are transported to the laboratory 4-days after production. Cylinders are then cured in high-humidity chamber (or water tank) for the specified curing period (e.g., 7-days, 28-days, etc.). On the date the cylinder has cured for the specified period of time, the cylinder is removed from the water tank and tested in compression with strength and failure mode reported.
