History of “SHIRASU” studies

Although “SHIRASU” had little or no value, our predecessors have not necessarily been sitting back with their arms folded.

Various researches on possibilities of utilization of “SHIRASU” have been carried out. It was used as a pavement subgrade material in the engineering field and also as land reclamation material. There has also been research in developing plaster material from “SHIRASU” but because of its qualities such as porosity, it was not authorized to be used as building material by the Architectural Building Codes.
