Optimization of imperfect reactive powder concrete slabs under impact load is the aim of the current study, the study adopts to investigate the optimal imperfection to decrease the maximum dynamic deflection which affects negatively on structures. Optimization by using Modified Hooke-Jeevs method of imperfect slabs has been adopted in three cases according to the required variables, optimal thickness, optimal thickness-length and optimal thickness-length-imperfection. The results show that the optimal ratio of imperfect reactive powder concrete slab thickness to the one of its dimension is equal to (0.049) whereas the optimal ratio of imperfection to the thickness of slab is equal to (0.785) . The current study adopted preparing designable table which is considered informative for any future designs.
