Abstract

Cracking generated by shrinkage is a major concern, particularly in structures with a high surface area to volume ratio. It has been well established that the inclusion of fibers in concrete contribute to the shrinkage crack reduction. In the present study, the efficiency of different fibers in arresting the cracks in cementitious composites due to restrained plastic shrinkage was investigated. This paper focused on the effects of using steel, glass and polypropylene fibers at volume fraction of 0.1%. Crack characteristics including the maximum crack width, average crack width, and total crack area were measureed using the image analysis. The test results indicate that steel fibers were more effective in reducing restrained plastic shrinkage cracking compared to others whereas glass fibers had better performance than polypropylene fibers.
