Self-Compacting Concrete Using Sea Water and Sea Sand: SALSEC

In construction projects on isolated islands and in coastal areas with poor access, both in Japan and in other countries, it is difficult to secure the necessary supply of materials and manpower. Therefore, a concrete that enables concrete manufacture and construction with good efficiency using materials that are readily available in the local area is demanded. In joint research with a group of six government agencies, university, and companies, Toyo Construction developed “SALSEC,” which is a concrete with low viscosity in comparison with conventional high workable (high fluidity) concrete, and also has an excellent self-filling property, even when used with sea water and unwashed sea sand that contains salt. SALSEC is contributing to high efficiency in concrete manufacture and construction under special environments.
