GEOTECHNICAL APPLICATION OF CLASHED SHELL PARTICLES FOR ENVIRONMENTAL CONSERVATION AND CO₂ IMMOBILIZATION IN SHALLOW GROUND

Abstract

 This study demonstrates the possibility of reducing the amount of open-piled shell particles by using them as a soil structure material. Additionally, it shows the amount of carbon dioxide (CO₂) reduction potential for applying this material to reinforce the backside of river levees by unique geotechnical properties of flat scallop shells. First, the CO₂ emissions associated with the reduction of shell mass due to acid rain were determined by laboratory experiments. Then, this study estimates and evaluates the potential amount of carbon dioxide (CO₂) reduction resulting from the use of scallop shells as an embedded material in shallow ground. Finally, it clarified that the amount of CO₂ emission due to the reduction of shell mass by acid rain depends on the pH of the acid rain and the particle size of the shells etc. In addition, the potential of CO₂ emission reduction by the application to the reinforce the backside of river levees was clarified.
