Non-Destructive Testing of Concrete
The project was initiated to evaluate the performance of an ultrasonic testing device in predicting compressive strengths from tests performed on samples of fresh concrete. The initial phase of the study involved laboratory preparation of concrete cylinders using various water cement ratios. These were tested using ultrasonic equipment and the results were to be used in developing standard curves for predicting compressive strengths of fresh concrete. Results of the laboratory phase of the project were not encouraging. Very little predictability of compressive strength on sand and gravel mixes was possible until several hours after addition of water to the mixes. Experimentation with more homogeneous sand mixes yielded no better results. Further investigation with the present available equipment seems unwarranted. (Author)
