AASHTO T 106M/T 106-18 PDF Download

The AASHTO T 106M/T 106-18 standard outlines a method for determining the compressive strength of hydraulic cement mortar. This is achieved through the use of cube specimens with dimensions of either 50 mm or 2 inches. The standard emphasizes that this testing procedure should not be used for acceptance tests, as an alternative procedure outlined in ASTM C 349 is available for such purposes.

The standard likely provides detailed instructions on the preparation and conditioning of the mortar specimens, including the proportioning of materials and the mixing process. It may also outline the curing requirements, such as the temperature and duration, to ensure the specimens reach the desired strength. The procedure for conducting the compressive strength test itself would also be described, including the application of a load to the specimen until failure occurs. The standard may specify the criteria for acceptance or rejection based on the measured compressive strength values.
