Abstract

A study was undertaken to develop precision and bias statements for ASTM C 42. Seventeen laboratories participated in testing core specimens removed from concrete slabs. The results given herein are the basis for this statement. Additional information was developed pertaining to the relative strength between 56-day laboratory-cured cylinders and 56-day drilled cores.

Keywords:
bias, concrete, cores, compressive strength, precision
