석회암 성분의 부순잔골재를 사용한 모르터의 역학적 특성 = Mechanical Properties of Mortar Using Lime Stone Crushed Aggregate

다국어 초록 (Multilingual Abstract)

This study investigates engineering properties of mortar using limestone-crushed-aggregate (LS). Test resulted show, that increase of incorporating ratio of Ls had better fluidity than other specimens. This is due to the particle shape and continuous grade distribution of Ls. In addition, mortar incorporating more Ls exhibited lower air content, by the well-filling effects of the aggregate. Among specimens, It was found that Ls affected to the setting time of the mortar, resulting from acceleration of the initial and final setting time. For the properties of strength, specimens incorporating higher ratio of Ls had favorable strength, such as higher compressive, tensile and flexural values, Drying shrinkage length, change ratio of the specimens exhibited that Ls was the lowest and it reduced the shrinkage, as the incorporating ratio of Ls increased, due to the improved strength.
