Being forecasting manner of carbonation depth of the concrete

摘要

PROBLEM TO BE SOLVED: To provide a prediction method for the neutralization depth of concrete capable of determining simply and accurately the progression degree after several years of the neutralization depth of a concrete structure coated with a sheathing finish coating material.;SOLUTION: A chart or a table for showing the relation between a neutralization resistance and a material age of the finish coating material on the concrete structure is produced beforehand. After measuring the finish coating material and the material age of the concrete structure, the neutralization resistance is determined from the measured value by using the chart or the table, and the neutralization depth of the concrete structure is predicted from the determined neutralization resistance by using a fixed expression.;COPYRIGHT: (C)2005,JPO&NCIPI
