The main objective of this study is investigate of behavior of concrete containing waste tire rubber against impact loads. Impact is one of the dynamic loads that may be occurs at high velocity and exposed concrete structures, such as the military situation. Properties of concrete containing three different sizes of rubber particles 0-1, 1-3 and 3-5 mm that replaced of 0%, 10%, 20%, 30%, 40% and 50% of fine aggregate were determined. Analyses were included compressive and flexural strength, dry unit weight, velocity of ultrasonic wave and scanning of electron microscopy (SEM). For ductility of this kind of concrete, impact test done with gas gun device on it and failure such as penetration depth and average crater diameter determined too. The results indicated that when rubber particles added to concrete mixture, fracture of concrete was softer than normal concrete and concrete containing optimum size and percent of rubber particles has best properties and less failure.
