Utilization of cement-based materials for deep sea infrastructure

In recent years, demands for deep-sea utilization has been increasing from industries as well as natural science research, and the major utilization of the deep sea is being started soon. The authors have investigated the mix designs and construction methods of cementitious materials and structures for this trend. In this paper, our previous studies on the durability of cementitious materials under deep seas and in-situ casting tests of cementitious materials on deep seafloor are introduced.
