At stone monuments and base rocks, slide, freeze damage, biodeterioration, have occured, and especially salt weathering is serious. It was difficult to compare objectively that the content of salts and the sta te of degradation, and to get to know what salts are contained in the base rocks without a crystal until now. Then, when the concentration of the sodium chloride on the surface of the base rocks was measured by a new method, the very high concentration was detected in the place which does not have the efflorescence. Although, weathering speed is said to be late and an influence is said to be little compared with a sulfate mineral, it is clear from the value that the degradation by sodium chloride has occurr ed and the weathering speed and influence must not be made light of, either. Therefore, the measurement of the chloride is considered to be an effective method for judging salt weathering objectively.
