| Abstract |
Recently because of the lack of natural aggregate, crush saggregate is used. But it is apt to develop initial shrinkage crack and shrinkage crack by plastic and dry shrinkage. so to reduce crack, various attempt like mixing aggregage and reinforcing fiber is doing. However, the basic researches about the quantitative evaluation for concrete's shrinkage crack is lacking. Currently, method of test for drying shrinkage cracking of restrained concreteis to used to evaluate shrinkage in domestic. This study is trying to perform plat-ring restrained shrinkage test as well as method of test for drying shrinkage cracking of restrained concrete through a sort of mixing factors. As a result of experiment, crack point was discovered when using crush aggreage and unit water is high in plat-ring test. And reinforced fiber did not affect at crack initiation time in test for drying shrinkage cracking of restrained concrete. |
