There is a concern among ready mixed concrete producers that quality assurance testing is not consistently performed in accordance with ASTM standards. All project participants are affected by substandard testing practices, as false-positive or false-negative test results can lead to rejections of good concrete loads or acceptance of bad quality concrete, respectively. The article makes recommendations for evaluating and improving the quality of concrete testing, and it describes a program that allows testing agencies and their technicians to assess their performance relative to their peers.
