고막 패각을 잔골재로 사용한 철근콘크리트 보의 전단 거동에 관한 연구

A Study on the Shear Behavior of Reinforced Concrete Beams Using of Cockle Shells as Fine Aggregate

  • 발행 : 2004.06.01

초록

1) As result of specimen with shear reinforcing bar of reinforced concrete beam, ductile coefficient of specimen was high in specimen containing Cockle shells based on non-mixed specimen. In increase rate of specimens, yield strength was similar in specimens containing Cockle shells and non-mixed specimens and maximum strength was higher in specimen containing Cockle shells. 2) To sum up the above experimental results, it is found that using splitted Cockle shells as aggregate for concrete by 10%~ 15% showed the same or higher compressive strength and shear strength as concretes using general aggregate and it can be used as substitute aggregate of concrete. It is considered that for future use of splitted Cockle shells as substitute concrete aggregate, continuous researches of its durability, applicability and economy are needed.
