| Outline of Final Research Achievements |
The construction management system using absorption characteristics of building materials is proposed. In the system, the in-situ measurement method using ensemble averaging technique, namely EA method, is adopted as a measurement method of absorption characteristics. First, the reproducibility of EA method was confirmed through round-robin measurements. Next, measurements for multi-layer materials were conducted, and it confirmed that difference of absorption characteristics due to a slight difference in structure of materials are measurable by the EA method. Finally, the proposed method is applied to the evaluation of quality in material development, and the availability of the system is shown.
