Abstract

Tensile as well as flexural strengths of concrete can be substantially increased by introducing closely spaced fibers that would obstruct the propagation of microcracks, therefore delaying the onset of tension cracks and increasing the tensile strength of the material. Fibers of various shapes and sizes produced from steel, plastic, glass and natural materials are being used. In this study, we used cellulose chip fiber to decrease the shrinkage crack in mortar and concrete. Specially, we have studied the dispersion characteristic of cellulose chip fiber. As a result, it was assumed that the slurry type of cellulose chip fiber is very effective to disperse the fiber in mortar and concrete.
