In recent years, many seabed structure materials are needed for extraction of methane hydrate and submarine hydrothermal polymetallic ore in Japan. Although covering material is required to make the protection disturbance for environmental issues at seabed, it has high mobility, and does not bleed, etc. after construction. Therefore, a construction material which uses a material mixture of the surface-active agent with fly ash was developed. Usage of fly ash instead of cement leads to improved mobility, reduced construction cost and so on. In considering these points, in order to clarify to what degree the contents of surfactant affects the properties of the injected fly ash mixture into the construction of seabed structures, different combinations of fly ash, surfactant and water were considered by means of multiple experiments.
