Infrastructure Materials Engineering Lab
Machine-translated · View original
The lab investigates how concrete deteriorates and develops materials that help reduce CO₂ emissions.
AboutAbout the lab
You were born in an age when the mysteries of concrete can be solved.
The Infrastructure Materials Engineering Lab studies inorganic materials used in infrastructure facilities, especially concrete.
Because concrete deteriorates at different rates depending on the environment in which it is placed, the lab considers it important to investigate the speed and mechanisms of deterioration and link them to maintenance and management.
The lab holds that it is desirable to contribute, from a materials perspective, to efforts to reduce environmental impact toward a decarbonized society and a recycling-oriented society.
In experiments, the lab takes a broad perspective from the nanoscale to the macroscale, and in computation, it tackles problems using data science such as Thermodynamic Modelling.
Key terms
- Thermodynamic Modelling
- A method of calculating the reactions of substances using thermodynamic databases. It is used to study deterioration that is difficult to reproduce.
- Industrial by-products
- Materials produced during the manufacturing processes of other industries. This lab uses them in construction materials.
- Carbon dioxide-absorbing concrete
- Concrete that makes use of the carbon dioxide-absorbing property of calcium-rich concrete.
ResearchResearch themes
The Infrastructure Materials Engineering Lab studies a wide range of concretes using techniques that capture invisible microstructures and material changes with X-rays and electron beams, techniques that identify components from the thermal decomposition temperatures of chemical substances, and Thermodynamic Modelling. The main themes are elucidating chemical deterioration mechanisms, developing new construction materials with carbon neutrality in mind, and evaluating the amount of carbon dioxide absorbed by concrete.
*Illustrative imageElucidating the Chemical Deterioration of Concrete
The lab investigates deterioration in environments that are difficult to reproduce in experiments, such as the deep sea and the pedestal of the reactor following the Fukushima Daiichi nuclear power plant accident, through theoretical calculations using Thermodynamic Modelling. It also elucidates the formation mechanisms of precipitates whose causes are unclear, using both experiments and numerical calculations.
*Illustrative imageNew Construction Materials Aimed at Reducing CO₂
Because reducing emissions is meaningless if a material has a short lifespan, the lab studies how to make materials that use industrial by-products and carbon dioxide-fixing materials more durable. Taking life-cycle CO₂ into account, it works on creating materials that contribute to carbon neutrality.
*Illustrative imageEvaluating the Amount of Carbon Dioxide Absorbed by Concrete
Concrete is rich in calcium and can absorb carbon dioxide. Because the contribution of carbon dioxide-absorbing concrete to decarbonization cannot be evaluated without knowing how much it absorbs, the lab is advancing methods for evaluating the absorbed amount using the thermal decomposition of chemical substances.
