Research Theme of Material Research Team

Civil engineering structures in cold snowy regions are subject to the actions of freezing and thawing caused by low temperatures, and chloride ions from seawater and antifreezing agent. So they are deteriorated by frost or combined frost and chloride attack etc., and their functions are reduced by frost heaving or insufficient bearing capacity.
In order to improve durability and to appropriately maintain the functions of civil engineering structures for a longer period of time, in the Materials Research Team is conducting research to develop technologies to preserve structures such as quality control and maintenance, repair, reconstruction and other technologies to improve durability of concrete structures in the cold snowy environment
