Testing fresh concrete in the field. ASTM standards define pre- cise pro c e d u r es for per- forming field tests to deter- mine the quality of freshly mixed c o n c r ete. Usual field tests measure c o n s i s t e n c y, strength, unit weight, air content, and temperature (see box). Many test details may seem trivial, even arbitrary.
