The experimental study of nubbly corundum's sizeaffection to characteristics of anti-penetrationof nubbly corundum concrete

Nubbly corundum concrete is a new type defending material. Many factors can affect it's anti-penetration characteristics. In this paper the factor of the size of nubbly corundum is experimentally studied. The results indicate that the bigger the nubbly corundum and the more tightness the nubbly corundum be laid and the more effective in anti-penetration of nubbly corundum concrete. On the enhancing of material's anti-penetration capability, it's better to make projectile damaged than to make projectile yaw.
