본 연구의 목적은 ALC 블록대체를 위한 고성능 기포콘크리트 배합설계를 개발하는 것이다. 대기양생 하에서 기포콘크리트의 고강도 발현(특히 초기재령에서)을 위하여 결합재 및 혼화제를 사전연구에서 다음과 같이 설계하였다. 규산3칼슘이 60% 이상인 보통포틀랜드시멘트에 무수석고 3%를 첨가하였으며, 폴리카르본산계 감수제에서 폴리알킬에테르 성분을 28%로 조절하였다. 이들 재료를 사용하여 물-결합재비와 단위결합재양을 변수로 기포콘크리트 11배합을 실험하였다. 배합된 기포콘크리트의 품질 및 실용성은 KS 규격의 ALC 블록의 요구조건 및 기존의 일반 기포콘크리트와 비교하였다. 실험결과 본 연구의 고성능 기포콘크리트는 ALC 블록의 요구조건을 만족하면서 높은 실용가능성을 보였다.

The bearing capacity of the wall against the eccentric load when the washbasin was attached on the ALC block wall was tested. Test methods are BS EN 14688 and BS 5234-2. Tests in accordance with BS EN 14688 showed that the holding capacity of steel was much stronger and more stable when HA-II (chemical anchor) was used than when the washbasin was fixed using HA-I (plastic anchor). As an experimental result according to the Annex K of BS 5234-2, the bearing capacity of ALC block wall corresponded to the "stage in which the force works(performance grade) 1,500N" for all of the cases where a washbasin is fixed using two types of the wall's dedicated anchors(HA-I and HA-II).

Interior stone walls are using commonly in non-bearing lightweight walls of apartments. The stones of interior wall were two types, one is a granite stone, another is a marble stone. Granite stone is attached by the epoxy adhesive and marble stone is attached by dedicated anchor and fastener. The impact resistance test was carried out interior stone walls in accordance with KS F 2613. The test methods included the impact resistance tests by each of soft impact body and hard impact body. The results of the test have proved that interior stone walls can withstand the soft impact bodies and hard impact bodies that are likely to happen in everyday life.

현대사회 건축물들의 고층화로 인하여 구조물의 중량부담 경감의 필요성이 대두되고 있다. 이에 따라 비구조용 재료로 경량기포콘크리트의 수요가 꾸준히 증가하는 추세이다. 다공성 세라믹스(ALC)는 가장 대표적인 경량기포콘크리트로서 경량블록 등의 건축자재로 많이 사용되고 있다. 본 연구는 원료의 입도 및 함량 제어를 통하여 저 고비중 ALC의 물리적 특성을 확인하고자 하였다.

본 논문에서는 개인용 컴퓨터와 CCD 카메라를 이용하여 실시간처리에 의해 생산 공정에서 자동으로 경량기포 콘크리트 블록의 각종 치수 측정을 할 수 있는 시스템 설계방법을 제안하였다. 또한 제안한 치수측정 자동화 알고리즘은 실제 작업환경을 고려하여 이중에지를 고려한 경계결정방법, 작업공정내의 피사체의 진동을 고려한 단위길이 결정방법, 카메라의 곡률보정에 의한 치수오차 보정 방법 등을 적용함으로써, 고성능의 하드웨어 장비를 이용하지 않고서도 실제공정에서의 실험결과를 통해 모든 경량기포 콘크리트 블록의 치수에 대해 1mm이내의 오차를 보장하므로, 설계한 시스템이 적합한 치수측정 시스템임을 확인할 수 있었다.

A system design technique of automatic thickness measurement and defect inspection system, which measures the thickness of the ALC(Autoclaved Lightweight Concrete) block and inspects the defect on a realtime basis is proposed. The image processing system was established with a CCD camera, an image grabber, and a personal computer without using assembled measurement equipment. The image obtained by this system was analyzed by a devised algorithm, specially designed for the enhanced measurement accuracy. For the realization of the proposed algorithm, the preprocessing method that can be applied to overcome uneven lighting environment, an enhanced edge decision method using 8 edge-pairs with irregular and rough surface, the unit length decision method in uneven condition with rocking objects, and the curvature calibration method of camera using a constructed grid are developed. The experimental results, show that the required measurement accuracy specification is sufficiently satisfied using our proposed method.
