Engineering Characteristics of Resource-Cycling Mortar according to the Variation of Illite Replacement Ratio and Fine Aggregate Type

굵은골재 및 잔골재 조합변화가 초고강도 콘크리트의 기초적 특성에 미치는 영향

This study has analyzed the engineering characteristics of resource-cycling mortar according to the variation of fine aggregate type using illite with high development potentials by setting the goal as developing eco-friendly construction materials. As a result, while flow has increased if recycled fine aggregate and waste refractory are used separately or mixing them adequately in case of flow and compressive strength, the flow had somewhat declined followed by illite replacement. However, the possibility of such usage is determined to be adequate if used by mixing illite, recycled fine aggregate and waste refractory properly due to the dry shrinkage effect.
