시멘트복합체 보강용 셀룰로오스 나노크리스탈(CNC)의 분산성 평가

초록

The Cellulose Nanocrystal (CNC) of dispersion condition is important factor when reinforce concrete or cement composite as CNC, because it is closely related to the strength reinforcement. Before the CNC is utilized to reinforcement of concrete or cement composite, it is essential to evaluate the dispersion properties. Therefore, the objective of the present study is to evaluate the dispersion of CNC. In this experiment, the specimen was prepared to the type of CNC suspension in accordance with weight ratio of CNC and the dispersion time of sonication. The first property, the dispersion properties of CNC, was evaluated by measuring turbidity and absorbance. The second property, the dispersion stability, was measured through the sediment time.
