The purpose of this study is to review the available literature on the effectiveness of fibers in preventing early-age shrinkage cracking on cementitious concrete. The overview describes the widely used ASTM C1579 (Standard Test Method for Evaluating Plastic Shrinkage Cracking of Restrained Fiber Reinforced Concrete (Using a Steel Form Insert) for plastic shrinkage cracking. The past literature used crack length, width, or area to describe and quantify cracks on concrete specimens. To keep things simple, this review expresses the length, width or area as a percentage of the control specimen. Finally, the study establishes a relationship between fiber volume and aspect ratio on plastic shrinkage and compressive strength of concrete. It was concluded that fiber is sufficient enough to mitigate plastic shrinkage cracking. An increase in fiber volume and aspect ratio reduces the early-age cracking of concrete but harm its compressive strength.
