Research on the Chemical Deterioration Mechanisms of Concrete
We conduct detailed investigations into the degradation mechanisms from a chemical perspective for representative factors causing deterioration in steel embedded in concrete or reinforced concrete, such as carbonation (neutralization), salt damage, and sulfate deterioration (chemical erosion). By modeling these degradation phenomena, we predict future deterioration.

Research on Mass Transfer within Concrete
The behavior of cesium within concrete following decontamination work, after radioactive cesium released by the nuclear accident settled on concrete due to rainfall, etc., and the behavior of industrial byproducts and industrial waste when effectively utilizing them as concrete materials, such as the long-term behavior of hazardous heavy metals contained in industrial waste within concrete, often becomes important alongside the behavior of water. Industrial waste. The behavior of substances inherent in concrete, along with water behavior, is often critical. We are experimentally investigating the existence forms and behavior of these substances, including water, within concrete.

Research on Enhancing the Performance of Fly Ash Concrete
We aim to effectively utilize fly ash, a byproduct of coal-fired power generation, by enhancing the performance of fly ash concrete. To achieve initial strength development, long-term strength gain, and high durability, we are evaluating curing conditions (including internal curing) and mix design parameters, assessing the contribution of fly ash to strength and durability under each condition. We are comprehensively evaluating the performance of fly ash alone and in concrete to realize high-performance fly ash concrete.

Development of an Internal Curing Method Using Porous Ceramics (Recycled Roof Tiles) and Evaluation of Enhanced Crack Resistance
Self-shrinkage associated with the hydration of Ultra-High Strength and Ultra-High Durability (UHSC) concrete, along with cracks caused by self-shrinkage and delayed strength development in concrete using waste resources such as blast furnace slag fine powder and fly ash, pose significant problems in terms of reduced durability. We are focusing on high-strength, highly porous ceramics with high water absorption rates, aiming to elucidate the mechanism for improving crack resistance by using them as part of the aggregate.
