건축물은 일반적으로 적벽돌이나 또는 시멘트 블록 등을 쌓아 건물 벽체를 시공하며, 건물의 단열성을 높이기 위해 벽체 시공시 단열재를 사용함에 따라 단열재 내외부에 중량감이 있는 블록을 이중으로 적층시켜 시공함에 따라 건축물에 가해지는 하중에 의해 벽체에 균열 등이 발생하는 문제점이 있었다.Building walls are generally constructed by stacking red bricks or cement blocks, and in order to increase the insulation of the building, insulators are used during wall construction. There was a problem in that cracks occurred in the wall due to the applied load.
따라서, 최근에는 건축물에 가해지는 하중을 최대한 줄이기 위해 경량화시킨 벽돌이나 또는 블록의 개발이 다양하게 진행되고 있으며, 이와 같이 다양하게 개발되고 있는 경량블록에 관한 특허들을 살펴보면, 대한민국등록실용신안공보 제20-0384157호(2005.05.11.)의 경량 콘크리트 블록과, 대한민국등록실용신안공보 제20-0317115호(2003.06.25.)의 건축용 경량 블록 등이 알려져 있지만, 상기와 같은 블록들의 경우에는 블록 내부에 다수의 관통공들을 형성시켜 블록을 경량화시킴에 따라 블록의 압축강도, 휨강도 및 인장강도 등과 같은 물리적 특성이 저하할 우려가 있다.Therefore, in recent years, the development of lightweight bricks or blocks has been variously progressed in order to reduce the load applied to the building as much as possible. -0384157 (2005.05.11.) lightweight concrete block and Republic of Korea Utility Model Publication No. 20-0317115 (2003.06.25.) lightweight blocks for construction are known, but in the case of such blocks, As the block is lightened by forming a plurality of through holes, there is a fear that physical properties such as compressive strength, flexural strength and tensile strength of the block may be deteriorated.
따라서, 상기와 같은 문제점을 해결하기 위하여, 블록 내부에 관통공들을 형성시키지 않고 섬유를 혼입하여 블록을 경량화시키는 기술이 개발되고 있으며, 관련 특허들로써, 대한민국등록특허공보 제10-0620866호(2006.09.13.)의 강섬유 보강 시멘트 복합체와, 대한민국등록특허공보 제10-1236604호(2013.02.22.)의 초고강도 섬유 보강 시멘트 조성물 등이 공개되어 있다.Therefore, in order to solve the above problems, a technology for reducing the weight of the block by mixing fibers without forming through-holes inside the block is being developed. 13.) and the ultra-high strength fiber-reinforced cement composition of Korean Patent No. 10-1236604 (February 22, 2013) have been disclosed.
하지만, 상기와 같은 기술의 경우, 콘크리트의 취성파괴 등을 방지하기 위해 일반 콘크리트의 배합에 강섬유 및 유기섬유 등을 혼입하여 제조하는 섬유 보강 콘크리트(fiber reinfored concrete)로써, 일반 콘크리트의 배합에 섬유를 투입하므로 콘크리트의 점성 부족으로 섬유를 다량으로 투입하지 못하여 만족할 만할 인성을 확보하지도 못할 뿐더러, 섬유 뭉침(fiber ball) 현상이 발생하여 오히려 콘크리트의 성능을 저하시키는 경우도 발생하고 있다.However, in the case of the above technology, as fiber reinforced concrete manufactured by mixing steel fibers and organic fibers in the general concrete mixture to prevent brittle destruction of concrete, fibers are added to the general concrete mixture. Because of the lack of viscosity of concrete, a large amount of fiber cannot be added, so satisfactory toughness cannot be secured, and fiber ball phenomenon occurs, which actually deteriorates the performance of concrete.
또한, 섬유 혼입으로는 고강도 콘크리트의 취성파괴를 완전히 방지하지 못하여, 지진 또는 차량의 반복 및 충격하중, 화재 및 자연 열화현상 등이 발생하였을 때 곧바로 구조물이 파괴되는 등 기계적 강도와 같은 물리적 특성에 여전히 취약점을 안고 있다.In addition, fiber mixing does not completely prevent brittle fracture of high-strength concrete, so it is still affected by physical properties such as mechanical strength, such as destruction of structures immediately when earthquakes or repeated vehicle impacts, shock loads, fires, and natural deterioration occur. has vulnerabilities.
