In this paper, the authors conducted an experimental study on the seasonal variation of measured values for "Water Intentional Spraying Test" developed as a nondestructive evaluation method of cover-concrete quality that can be used by the practitioner responsible for ordering construction work and construction management. Verification experiments have shown that the effects of temperature and water content are greater in poor quality concrete. Moreover, although the remarkable increase in the repetition number of watering was confirmed in the low temperature environment, it was suggested that the effect could be reduced by using normal temperature water.
