Study for resistance Plastic Shringage Cracking and apply field of Cellulose Fiber Reinforced Concrete

셀룰로스 섬유의 소성수축균열 저항성과 현장적용에 관한연구

Plastic shrindage cracking occurs at the exposed surfaces of freshly placed concrete due to consoilidation of the concrete mass and rapid evaporation of water from the surface. This so called shrindage craking is a major concern for concrete, especially for been performed to obtain the plastic shrindage porperties of cellolus fiber reinforced concrete. The results of tests of the cellolus fiber were compared with plain and polypropylene fibers. Test results indicated that cellolus fiber reinforcement showed an aility to reduce the total crack area and maximum crack width significantly.
