SELECTION OF COMBUSTION ASH MINERAL SOURCE ESSENTISL FOR SEDIMENT ENVIRONMENT AND CHEMICAL CHARACTERISTICS BY HYDRATION SILIDIFICATION

Abstract

 Ages sediment (acidification, reduction) inhibits the inhabiting of organisms in the coastal area where minerals are lacking. Effect of combustion ash elute minerals have a very important role in the activity of organisms, and it was possible to confirm reproduction of benthic organisms by scattering GCA (granulated coal ash) on ages sediment. Coal ash (FA) composed of oxides such as amorphous SiO₂, Al2O3, CaO, Fe₂O₃ and bamboo ash (BA) that can elute K⁺ and Mg²⁺ are expected to promote coastal ecosystem regeneration. Dissolution characteristics of BA-GCA granulated by FA and BA are evaluated experimentally by dissolution test and combustion test used BA-GCA. And we clarified the basic matters on the development of recycled materials for Environmental purification of reduced soil.
