탄소섬유 보강시멘트 복합체(CFRC)의 공학적 특성에 관한 실험적 연구(I)
A Study on the Engineering Properties of Carbon Fiber Reinforced Cement Composites(I)
초록
In order to discuss the engineering properties of carbon fiber reinforced cement composites with silica fume and silica powder, experimental studies in the CFRC were carried out. The types of fiber used which are in CFRC are PAN-based carbon fiber and Pitch-based carbon fiber. To examine the effects of types, lengths, contents of carbon fiber and matrices, their properties of fresh and fardened CFRC were tested. According to the test results, the process technology of light-weight CFRC is developed and their potimum mix proportions are successfully proposed. Also, it can be concluded that the reinforcement of carbon fiber is considerably effective in improving tensile strenghth, flexural strength, toughness and loss of shrinkage of CFRC compared with conventional mortar.
