using of concrete lining for erosion control water conveyance channels in mountainous and impassable ways in many areas due to high cost of providing and transportation materials is not economical. This Parameter in gypsum soils due to the higher solubility and erosion is Very important. Previous studies show that additives cement and the other materials to Location soils, can increase compressive strength soils .The application of micro silica for stabilization gypsum soil and Evaluation of erosion and compressive strength could have major differences with previous research. In the present study, the erosion and compressive strength due to jet flow plane with samples analyzed. Results indicate that, the incipient erosion in samples dependent with speeds, angles and times of erosion. For samples with 10% micro silica, velocity 4 m/s and impact angle vertical (Ө=00) the mixture of 10% cement at 6 hours and the mixture of 12% cement at all of time (8 hours) and velocity 6 m/s and impact horizontal (Ө=900) both of mixture (10% and 12% cement) all of time (8 hours) of experiment were resistance to erosion.
