This test method measures the load-induced time-dependent compressive strain at selected ages for concrete under an arbitrary set of controlled environmental conditions. This test method can be used to compare creep potentials of different concretes. A procedure is available, using the developed equation (or graphical plot), for calculating stress from strain data within massive non-reinforced concrete structures. For most specific design applications, the test conditions set forth herein must be modified to more closely simulate the anticipated curing, thermal, exposure, and loading age conditions for the prototype structure. Current theories and effects of material and environmental parameters are presented in ACI SP-135, Symposium on Creep and Shrinkage of Concrete: Effect of Materials and Environment.
WJE laboratories are accredited by AASHTO (R18) and ANAB (ISO/IEC 17025) to perform testing standard ASTM C512 for Creep of Concrete in Compression.
