Shrinkage of Micro-Synthetic Fiber-Reinforced Mortar

Repair materials have been developed in this research by adding micro-synthetic fibers cement-based mortar. In addition, accelerator is incorporated the mortar to obtain high early strength of repair materials. Their shrinkage behavior interest. This study aims determine fiber-reinforced and propose models reflect their behavior. The results show that rapid developments are observed at an age where 3-day already attains about 40–50% 84-day value. Moreover, after 14 days curves tend approach asymptotic ACI 209.2R-08 CEB-MC 90-99 do not shape Therefore, proposes a modified can describe accuracy has confirmed quantitatively using method best fit line, residual analysis, coefficient error.
