Abstract

The durability of a concrete structure is improved when cracks in the concrete are dispersed and their widths are reduced. The purpose of this research is to find an effective method for dispersing cracks. The relationships between the reinforcing ratio and the concrete cracks’ widths are known. Also, glass fiber is used as a countermeasure for the cracks. Here, the cracks’ dispersing performance was checked using a tension test on the reinforced concrete member. In this study, three types of specimens reinforced by a glass fiber sheet or by crack control rebar were tested. From the experimental results, the cracks’ dispersing performance was observed in all specimens. However, it became clear that the quality of the cracks’ dispersing performance depends on the reinforcing material.
