Abstract

$CO_2$ emitted from building materials and construction materials industry reaches about 67 million tons, which occupy about 30 % of $CO_2$ emitted from the construction field. Controls on the use of consumed fossil fuels and reduction of emission gases are essential for the reduction of $CO_2$ in the construction area as we reduce the second and third curing to emit $CO_2$ in the construction materials industry. Accordingly, this study applied the low energy curing admixture (hereinafter "LA") to the extruded panels to observe the physical properties, depending on the mixing amount of fiber, type of fiber and mixing ratio of fiber. The type of fiber did not appear to be a main factor to affect strength, while the LA mixing ratio and mixing amount of fiber appeared to be major factors to affect strength. Especially, the highest strength was developed when the LA mixing ratio was 40%, whereas the test object with the mixing ratio of 50% resulted in the decrease of strength. In addition, it appeared that the mixing ratio of fiber greatly affected flexural strength and strength increased as the mixing ratio increased.

건설 분야 중 건설 재료와 건자재 산업에서 발생하는 $CO_2$는 약 6,700만톤으로 건설 분야에서 발생하는 $CO_2$의 약 30%를 점유하고 있다. 건설 분야에서 $CO_2$ 저감은 건자재 산업에서 $CO_2$를 발생시키는 2차, 3차 양생을 줄여 소비되는 화석연료 사용과 배출 가스 저감의 조절이 필수적이다. 따라서 본 연구는 저에너지양생용 혼합재(Low energy curing Admixture 이하 LA)를 압출성형패널에 적용한 후 그 혼입량, 섬유종류, 섬유 혼입율에 따른 물리적 특성을 관찰하였다. 섬유종류가 강도에 영향을 나타내는 주요한 인자는 아닌 것으로 나타났으며, LA 혼입율과 섬유 혼입량은 강도에 영향을 주는 주요한 인자인 것으로 나타났다. 특히 LA 혼입율 dl 40% 일 때 가장 높은 강도발현을 나타냈으며, 50% 인 시험체의 경우 강도가 하락하는 결과를 나타냈다, 또한 섬유 혼입율은 휨강도에 크게 영향을 주었으며 혼입율이 증가할수록 휨강도는 증가하는 것으로 나타났다.
