Abstract
Various types of fibers are utilized in cementitious materials in order to improve their performances. Here, the extent of fiber dispersion is of key importance regardless of the purpose of using fiber. In this study, activated carbon fiber dispersion in mortar samples was evaluated using electrical resistivity method. In particular, the extent of fiber dispersion was compared per mixing methods and surface treatments. The results suggest that the surface resistivity method is capable of evaluating dispersion of activated carbon fiber and that ultrasound dispersion method is superior to mortar mixer and hand mixer method. The use of superplasticizer improved dispersion but acid treatment was not effective.
