Iwanami Lab
Machine-translated · View original
A lab that reconnects everything from materials to planning for infrastructure, with maintenance and management at its core.
AboutAbout the lab
Building infrastructure without stopping at construction
Iwanami Lab develops technologies to support society stably, with "maintenance and management" as its keyword.
It aims for next-generation infrastructure management that unifies materials development, structural design, and maintenance and management, which have developed separately.
Going beyond the academic boundaries of structures, materials, and planning, the lab proposes how future society should be, based on a new "design" from a multiscale perspective of time and space.
It covers a wide range of fields, from materials such as concrete, steel, and new materials to civil engineering planning, sociology, and economics.
Key terms
- Maintenance and management
- Thinking through the whole life of a structure, from planning and design to construction, service, repair and strengthening, removal, and recycling, so that it can continue to be used.
- Infrastructure
- Facilities such as roads, bridges, ports, and water supply and sewer systems that support people's lives and the economy.
- Multiscale
- An approach that looks together at things of different sizes and time spans, from molecule-scale phenomena to society hundreds of years ahead.

ResearchResearch themes
The lab's goal is to create next-generation infrastructure management that unifies materials development, structural design, and maintenance and management, all of which have developed individually. It covers the broad range of fields needed to build a system that considers everything comprehensively, from design through construction, service, maintenance and management, and demolition.
*Illustrative imageConcrete That Withstands the Deep Sea
Structures in deep water need concrete that can withstand strong water pressure and seawater. The lab experimentally examines strength and how components leach out under high water pressure, and also conducts tests in which loads are applied to beams in the deep sea.
*Illustrative imageRepairs That Protect Rebar from Chloride Damage
When salt from the sea penetrates concrete, the reinforcing bars rust and the structure weakens. The lab examines how effective desalination methods, electrochemical methods that use electric current to prevent rust, and surface coating materials that block salt are, so that existing structures can be used longer.
*Illustrative imageEco-Friendly Materials That Make Use of Waste
To reduce the CO2 and waste generated by construction, the lab investigates the properties of materials made with aggregate from demolished concrete, waste glass fiber, and slag from power plants, and links the results to low-carbon design.
