The objective of this project was to develop a water-cement ratio measurement meter for easy, rapid and reliable use in the field. The goal was that the equipment be portable, easy to use, low cost and low maintenance, and be able to provide consistent and accurate results. A prototype device has been developed to measure the water-cement ratio of a plastic concrete mix. The method is based on the turbidity of water-cement slurry separated from a concrete mixture by "pressure sieving". Consistent results were obtained for both air entrained and non-air entrained concrete. Statistical analyses of the test results have shown that the Kansas Water-Cement Ratio Meter can measure the water-cement ratio of fresh concrete with an accuracy of +/-0.01 with 90% confidence. The test time is less than 10 minutes which includes cleaning the equipment. Further evaluation with admixtures, and under field conditions are planned

This project's objective was to evaluate and/or develop methods for the measurement of 1) the air content and uniformity of distribution; 2) cement content and uniformity of distribution; 3) water content and uniformity of distribution; and 4) thickness of cover over reinforcement. The measurement of these factors was to be made at the earliest desirable or feasible age in order that any necessary corrective measures could be immediately applied to the work in progress.
