We are working with different fielders on the edges of architecture, including materials, sensing, non-destructive diagnostics, and living environment microbiology.




Our research focuses on reinforced concrete members, mainly structural members, interior and exterior. As a basic research, we are working on durability evaluation and maintenance of reinforced concrete, and as a part of this, we are promoting joint research on the development of pH sensors. In addition to the collection of basic data that contributes to long-term performance prediction and the development of deterioration prediction models, we are also working on the evaluation of CO2 fixation capacity, which is expected of reinforced concrete.
As a new non-destructive diagnostic technique applicable to both structural members and interior/exterior materials, we are conducting research focusing on microbial community structure. This is a joint research project with the Department of Microbial Ecology, and we are planning to develop materials for controlling microbial living environments by utilizing the microbial community structure data obtained through this research.
As described above, we are working with researchers in other fields on themes slightly outside of the conventional research fields of architecture.

Fundamental research on control of microbial environment in building space by material selection

The ultimate objective of this research is to improve the sanitary microbiological living environment through the selection of building interior materials. In the project period, we will focus on concrete and wood materials, which are typical porous building materials, and investigate how (1) materialological conditions (pore structure, surface moisture content, pH) and (2) temperature and humidity environmental conditions (temperature, relative humidity, ventilation), which change during the service life of both materials, affect the extinction (composition type, amount and composition ratio) of microorganisms living in the surface layer of the building. (species, amount, and composition ratio) of microorganisms inhabiting the surface layer.




Development of a Deterioration Diagnosis Method for Concrete Structures Using Microbial Diversity Index

This research project proposes a method to evaluate and predict the deterioration of concrete based on the diversity index of microbial communities in existing concrete structures, which are aging at a high rate worldwide. The research team consists of Dr. Maresca, who has a worldwide track record of analyzing the diversity of microbial communities in concrete, and young researchers specializing in concrete engineering and microbial environments. Through this research, we aim to help young researchers acquire the rare analytical know-how of Dr. Maresca and to propose and disseminate an infrastructure maintenance management system that can be implemented anywhere and by anyone as an engineering application of microbial community analysis.




Modeling the time-dependent behavior of cracks in concrete structures

In general, if tensile failure at the interface between the crack repair material and the building frame is assumed as the degradation mechanism, it is desirable to inject the repair material when the crack width is at its maximum and to apply mainly compressive stresses. However, if the crack opening and closing behavior is not properly understood, the ideal crack repair method described above is often not implemented.
Based on the results of this study, it can be seen that the repaired material is subjected to repeated compressive and tensile actions, and in addition, changes in the physical properties of the repaired material itself due to temperature changes must also be considered. In other words, if sufficient durability is to be expected from the repair material, it is important to correctly understand the expected crack opening and closing behavior and to select a material with the appropriate functionality.



Development of a Method for Measuring pH Distribution in Concrete Using a Multifunctional Fiber Sensor

Corrosion of reinforcing bars inside concrete is known to be affected by pH, chloride ion concentration, and water content around the bars, and quantitative monitoring of pH and chloride ions related to the corrosion phenomenon of reinforcing bars is strongly desired. The joint researcher, Assistant Professor Yanyuan Guo of Tohoku University, has realized a new implantable pH visualization probe by combining a semiconductor chemical image sensor that can visualize the distribution of ion concentrations and multifunctional fiber technology, and has successfully monitored pH changes in the brain of mice over time using this probe. The probe was successfully used to monitor pH changes in the brain of mice over time. This study proposes a method to continuously and over a long period of time acquire the distribution of pH from the surface to the interior of concrete using a multifunctional fiber sensor integrated with an ion-sensitive membrane developed by Dr. Guo.



Research and development on standardization of evaluation of CO2 fixation in concrete

The purpose of this research and development is to provide a standard means of evaluating the amount of CO2 fixation, to lead to healthy competition in the market for construction materials that apply CO2 fixation methods, and to provide consumers with appropriate disclosure of material performance, as it is expected that many CO2 fixation materials will be developed in the future. The purpose of this study is to provide a means to evaluate the amount of CO2 fixation in the construction materials market.
This is a joint research project with the University of Tokyo, Hokkaido University, University of the Ryukyus, and others. Hiroshima University is working on the advancement of methods for estimating the CO2 fixation capacity of actual structures with painted or cracked wall surfaces.
