ASTM C469 testing provides a stress to strain ratio value and a ratio of lateral to longitudinal strain for hardened cylindrical concrete at whatever age and curing conditions may be designated. ASTM C469 is a compression test whereby a load is applied with a ConstantRate ofTraverse (CRT) type machine until a specified stress.

ASTM C109 specifies the testing of hydraulic cement mortars, which involves compressing 2inch (50 mm) cube specimens to failure. For compression testing of concrete cubes we used an Industrial Series 150LX Model universal testing machine with Partner™ Software and a spherically seated compression platen assembly that met the alignment requirements of the standard.

Various international codes have specific testing standards for concrete slump test. These standards specify methods, equipment for determining the consistency of fresh concrete by the slump test. For acceptance and reliability, It is essential to maintain strict compliance with these standards during the slump test for concrete.
