CORPS OF ENGINEERS CONCRETE QUALITY MONITOR: OPERATIONS GUIDE
This report describes how to set up and use the Corps of Engineers Concrete Quality Monitor (CQM), a system for determining the water and cement content of fresh concrete. The CQM system makes it possible to judge the quality of concrete as it is being placed, thereby helping avoid the high cost of replacing defective concrete. The report lists equipment, reagent, and calibration requirements, and tells how to conduct the test. The results of validation tests indicate the CQM system is as accurate as the previously developed Kelly-Vail (KV) and CERL/KV methods, and that CQM water/cement ratios can be used to estimate both compressive and flexural strengths.
