폐벤토나이트 분말의 소성 및 냉각조건에 따른 모르터의 압축강도 발현특성에 관한 연구 = The Study on the Compressive Strength Properties of Mortar using Discarded Bentonite Powder by the Cooling Method after Heat Treatment

다국어 초록 (Multilingual Abstract)

As the bentonite is main material to prevent from collapse of drilling hole at underground excavation works, it is increased using quantity on construction industry day by day. But, the discarded bentonite that is over using at underground excavation works is caused various enviromental trouble as soil and water pollution est. Therefore, this study aims to propose a foundamental report for pozzolan reaction of discarded Bentonite powder by heat-treatment and cooling as concrete mineral admixture. To find out pozzolan reaction ability of discarded Bentonite powder by indirect cooling & cooling using of water after heat-treatment, the experiments are excuted flow test & compressive strength on age of mortar using discarded Bentonite powder.As a result of this study, discarded Bentonite powder can be utilized as concrete mineral admixture by heat-treatment and especially, pozzolan reaction ability of discarded Bentonite powder is superior to the situation of 600℃60min & cooling using of water.
