Compressometer for testing concrete stress-strain relation. A compressometer is a device used to determine the strain or deformation of a specimen while measuring the compressive strength of concrete specimens, generally a cylinder. It can be used for rock, [1] concrete, soils, [2] and other materials. For concrete, the device usually comprises ...
The ASTM standards also regulate the rigidity of the cone. It states in the procedure that when the cone is removed, it should be lifted up vertically, without any rotational movement at all. [6] The concrete slump test is known as "Standard Test Method for Slump of Hydraulic-Cement Concrete" and carries the code (ASTM C 143) or (AASHTO T 119).

The federal standard for LA abrasion testing was formally adopted by the ASTM in 1937. [10] Decades later, field studies found that the LA test results do not always correlate with reality, thus engineers outside of the United States developed different national standards like the French wet micro-Deval procedure or the British Standard 812.
