N2 - The use of high early strength materials minimizes the out-of-service time of the effective repairs. In this research, high early strength fiber reinforced rapid set materials (HES-FR-RSM) were developed for concrete repair applications in transportation infrastructures with low cracking potential. Three types of rapid set prepackaged repair materials were developed. The designed mixtures have included three types of fibers (steel, basalt, and carbon) with different volume fractions. The research also included developing finite element model (FEM) that could describe the real structural behavior. The optimized mixture that includes 0.5% steel fibers showed free shrinkage less than 300 microstrains. The proposed model is capable of computing the time-dependent restrained shrinkage strain and tensile stresses at various depths of repair layer. The model is also capable of predicting the actual time of cracking, representation, and distribution of cracks. Moreover, the prediction of this model showed a good agreement with the conducted experiment.
