PROBLEM TO BE SOLVED: To provide a method for estimating durability of concrete, capable of estimating durability of skeleton concrete with high accuracy.SOLUTION: In a method for estimating durability of concrete: strength of skeleton concrete at an original position is estimated; a relationship between the strength of the concrete and a gel void ratio is preliminarily obtained; and an indicator related to a microscopic structure of the skeleton concrete is calculated on the basis of this relationship and the strength at the original position. Moreover, the durability of the skeleton concrete is estimated on the basis of the indicator related to the microscopic structure of the skeleton concrete. In this method, the indicator related to the microscopic structure of the skeleton concrete is calculated more accurately by calculating the indicator related to the microscopic structure of the skeleton concrete once again while taking into account of not only an indicator related to the microscopic structure of the skeleton concrete theoretically obtained but also the strength of the skeleton concrete at the original position. As a result, the durability of the skeleton concrete is estimated with high accuracy. |
