Abstract

 Recently because of growth in concerning fiber, various type of compounded fiber for concrete has been developed. Wide researches are in progress following properties of fiber and physical properties of concrete following mixing rate. Among these, research on control of concrete's shrinkage crack has been working vividly since 1980s. As a result of this, some of the actual practices are now sold in market. However, the basic researches about the quantitative evaluation for concrete's shrinkage crack is not clear. It is short in adapting the data as actual remicon because types of fiber have been limited to polypropylene and so on. So, this study is trying to perform the basic data about the shrinkage crack characteristic of fiber reinforced concrete achieving data of shrinkage crack evaluation of fiber reinforced concrete considered condition of field mix which using suggested method of quantitative evaluation method for evaluation of concrete's plastic/dry shrinkage crack and grading distributed shrinkage crack charateristic of fiber reinforced concrete which used various fiber.
