QUICK CONCRETE TEST. CONCRETE STRENGTH EVALUATION SPEEDED BY CHEMICAL PROCESS

A chemical process that can be used to predict the 28-day strength of concrete within 15 minutes of its placement has produced favorable results in field tests. The Kelly-Vail test, as the process is called, predicts strength by measuring the water and cement content of a concrete sample using a chemical titration process. Laboratory tests show that the Kelly-Vail method is reliable, and the degree of its sensitivity is insignificant. Oregon State University CERF, in Corvallis has carred the process from the laboratory to the job site where field personnel have been performing the test in portable labs. Data is presently being compiled and a report is expected to be released soon.
