BARRIER FOR ABSORBING VERY HIGH POWER BULLETS AND USES THEREOF

This disclosure is directed to an improved ballistic concrete barrier for stopping projectiles with a kinetic energy of between about 1.0 kJ (750 foot-pounds) and 20.3 kJ (15,000 foot-pounds) in between about 3 inches and 10 inches. In one embodiment, the ballistic concrete barrier comprises (a) abo...

Zusammenfassung:This disclosure is directed to an improved ballistic concrete barrier for stopping projectiles with a kinetic energy of between about 1.0 kJ (750 foot-pounds) and 20.3 kJ (15,000 foot-pounds) in between about 3 inches and 10 inches. In one embodiment, the ballistic concrete barrier comprises (a) about 1 part by mass Portland cement; (b) about 0.5 to 1.5 part by mass fine aggregate; (c) about 0.005 to 0.15 part by mass fiber; (d) about 0.005 to 0.05 part by mass calcium phosphate; (e) about 0.005 to 0.05 part by mass aluminum hydroxide; and (f) about 0.0005 to 0.05 part by mass air entrainment additive, such that the ballistic concrete barrier is capable of stopping a fifty caliber bullet in less than 10 inches from a point of entry into the barrier.
