• Abstract:
  The objective of the project was to place a CERL/Kelly-Vail testing unit and a microwave oven in the field to perform tests of plastic concrete on construction projects.
  
  The CERL/K-V tests were to determine water and cement content of the concrete and were evaluated as a method of predicting 28-day concrete strength.
  
  Although the water and cement contents can be determined with a reasonable degree of accuracy, there are too many variables involved in the field to accurately predict strength.
  
  The microwave oven used in the defrost mode is a fast and accurate method to determine water content with a minimum of equipment and operator training.
