Soil-water characteristic curve, which is called soil retention curve, is required to explore water flows in unsaturated soils, relative permeability of water in multi-phase fluids flow, and change to stiffness and volume of soils. Thus, the understanding of soil-water characteristic curves of soils...

바이오폴리머의 종류는 무엇이 있나? | 이는 미생물에 의해 물과 이산화탄소로 완전히 분해되기 때문에, 자연에 무해한 친환경 물질로 여겨지고 있다. 치토산(85% deacetylated power), 폴리에틸렌 옥사이드(polyethylene oxide), 잔탄검(xanthan gum), 알지네이트 염(alginic acid sodium salt) 및 폴리아크릴산(polyacrylic acid) 등이 현재 많이 연구되고 있는 바이오폴리머의 일종이다(Cao, 2016). | |
바이오폴리머는 어떤 물질로 여겨지고 있는가? | 바이오폴리머는 바이오매스를 원료로 하여 만들어진다. 이는 미생물에 의해 물과 이산화탄소로 완전히 분해되기 때문에, 자연에 무해한 친환경 물질로 여겨지고 있다. 치토산(85% deacetylated power), 폴리에틸렌 옥사이드(polyethylene oxide), 잔탄검(xanthan gum), 알지네이트 염(alginic acid sodium salt) 및 폴리아크릴산(polyacrylic acid) 등이 현재 많이 연구되고 있는 바이오폴리머의 일종이다(Cao, 2016). | |
흙-습윤 특성곡선은 어떤 특성을 나타내는가? | 흙-습윤 특성곡선(SWCC)은 지반의 습윤 함유능력(Brady & Weil, 2010), 상대투수계수(Assoluline, 2001; Campbell, 1974; Fischer & Celia, 1999; Mualem, 1986; Vogel & Cislerova, 1988), 지반의 강도(Fredlund et al., 1996; Oberg & Sallfors, 1997; anapalli et al., 1996) 및 지반의 강성(Delage et al., 1998; Gens & Alonso, 1992; Pedarla et al., 2012)과 연관성을 가지는 지반의 특성을 나타낸다. 따라서, 흙-습윤 특성곡선(SWCC)의 이해는 지반의 거동을 이해하는 데 크게 도움이 될 것으로 기대된다. |
