반복가열냉각에 의한 수화시멘트 페이스트와 골재 분리 방법 = The Separating Method of Hydrated Cement Paste and Aggregate in Bake and Cooling Cycle

다국어 초록 (Multilingual Abstract)

Cement mortar and efficient disconnection of aggregate are indispensable for recycling of waste concrete, and the problem is with quality in the existing physical disconnection way, and the problem has been by application of a concrete recycling construction materials.
Specially, in case of recycled aggregate, the quality is lowered because of the fine aggregate powder which has a bad influence on flowability, a compression strength by adhesion of mortar on the aggregate face, and the case of recycled cement was added to during recycle cement. Therefore, a mortar and interfacial separation of aggregate are large in proper quality for concrete recycling is expected that affect.
This study based on the recycled cement manufacturing way which used an aggregate interfacial separation of waste mortar in this study so that the coefficient of thermal expansion of hardend cement paste and an the coefficient of thermal expansion of a fine aggregate are different in a recycled cement manufacturing way, but leaves a purpose.
