PROBLEM TO BE SOLVED: To provide an aerosol-type neutralization measurement device that maintains stable quality of a concrete-neutralization measurement liquid used for diagnosing the quality of concrete, is reduced in volatilization and degradation of contents, and is excellent in workability even in coating work.SOLUTION: In a neutralization measurement device, an aerosol-type can is filled with a concrete-neutralization measurement liquid, and a nitrogen gas or a liquefied petroleum gas, and the concrete-neutralization measurement liquid is jetted out in a misty state using pressure of the gas through a button operation. This allows detection of degradation of concrete because concrete neutralized due to degradation does not change its color when the neutralization measurement liquid is sprayed thereon. The can is made of aluminum or an aluminum alloy, with its inner surface coated with a resin, or the can is a tin can with its inner surface coated with a resin. |
