Title:
METHOD FOR MEASURING NEUTRALIZATION DEPTH AND SEAL FOR NEUTRALIZATION DEPTH MEASUREMENT
Document Type and Number:
Japanese Patent JP2017009290
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for measuring a neutralization depth capable of performing visual and simple measurement.SOLUTION: With a method for measuring a neutralization depth in a vertical direction to the surface of a cement concrete composition hardened body, a seal having a property of blocking a carbon dioxide gas is pasted on the surface of the concrete composition hardened body, the seal is detached after the elapse of a constant period under a condition subjected to neutralization, and a neutralization length from a peripheral location to a center location of the pasted seal is measured. Preferably, the surface of the cement concrete composition hardened body is a smooth surface subjected to no neutralization.SELECTED DRAWING: Figure 3
