Orthogonal experiments at concrete materials proved: notable errors will occur when using chemical catalyzing to predict the concrete strength. Errors are unavoidable since such methods have neglected much factors. Ground on test data, effects on concrete intensity were analyzed with changes of sand ratio, bigger aggregate, and environment humidity, cement components. Error origins of concrete intensity were found, and the fact of avoidless errors from chemical catalyzing was notarized. Materials testing combining with fieldwork, new technique was proposed for monitoring quality of fresh concrete in building site. So hidden trouble would be known betimes before elementary solidification in concrete. Practices indicated that this technique is simple and speedy, it can avoid the loss of doing over again in concrete structures and can effectively improve quality of concrete engineering.
