Method of estimating moisture of concrete structure and system of estimating moisture of concrete structure

摘要

PROBLEM TO BE SOLVED: To estimate a distribution of moisture in a concrete structure which is an estimation object.SOLUTION: When a neutron emitted from a neutron beam source 104 with a content of the chemical element density composition of the concrete and bound water as a condition based on a relation between the position of a neutron beam source 104 and the position of a neutron beam detector 106 is measured in the neutron detector 106 via a concrete structure 200, the response is modeled and analyzed by a radiation transportation calculation code including the Monte Carlo method and the SN method, and when the neutron emitted from the neutron beam source 104 is measured in the neutron detector 106 via the concrete structure 200, the response is actually measured, and the existence of the moisture in the concrete structure 200 is estimated using the actually measured response and the analyzed response.SELECTED DRAWING: Figure 1
