Research Topics

We enjoy the benefits of substance civilization, and lives have become remarkably convenient and comfortable. Concrete is the foundation of social infrastructure that supports this substance civilization. However, the act of building a structure with concrete, or the act of building concrete itself is an act that destroys the natural environment. I want to own a car, I want to travel abroad, I want to live with a flush toilet, a TV, a cooler, but I also want to protect the natural environment. Developing a sustainable society may be the answer to this contradiction of humanity. In this laboratory, we address the goals of a sustainable society from the concrete perspective.

Precast practical applications of PCa with super-high durability concrete

To extend the lifespan of damaged bridge girders and shorten the period of traffic regulation during renewal construction, precast concrete member with high durability is developed with blast furnace slag sand.
