Compressional Dust Alfvenic Shocks (CDAS) are investigated in an electron depleted dusty plasma with dust-ion collisional effects. The large amplitude CDAS are obtained after solving the coupled nonlinear equations numerically, while small amplitude CDAS are explored through the Kortweg-de Vries Burger equation. It is pointed out that the spatio-temporal scale lengths for the formation of CDAS are different than the compressional Alfvenic shocks in an electron-ion plasma. The amplitude variation of CDAS with different parameters is shown. The transition of oscillatory shocks to monotonic shocks is presented in 3-D plots with variation in collision frequency. The importance of the results to space plasma environments is also briefly discussed.
