US12480746 - Barrier for absorbing very high power bullets and uses thereof

This disclosure is directed to an improved ballistic concrete mixture which is operable to be cast in many forms such as blocks. The improved ballistic concrete mixture provides an effective 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 such as a fifty-caliber round. The improved ballistic concrete mixture is useful in the erecting of new structures which need ballistics protection or for retrofitting existing structures with ballistics protection.

The patent describes an advanced ballistic concrete mixture designed to absorb high-energy projectiles, effective against rounds like the fifty-caliber. This concrete can be molded into various structures for new constructions or retrofitting existing buildings to enhance ballistic protection.

Claim 1

1 . A bullet-absorbing concrete structure constructed with a concrete mixture comprising: (i) about 1 part by mass cement; (ii) about 0.5 to 1.5 part by mass fine aggregate; and (iii) about 0.005 to 0.15 part by mass fiber; wherein the bullet-absorbing concrete structure is constructed with at least two arms and at least one center stem; wherein the concrete mixture does not include preformed foam; wherein the concrete mixture is poured at a density of less than about 90.8 pounds per cubic foot. (i) about 1 part by mass cement; (ii) about 0.5 to 1.5 part by mass fine aggregate; and (iii) about 0.005 to 0.15 part by mass fiber; wherein the bullet-absorbing concrete structure is constructed with at least two arms and at least one center stem; wherein the concrete mixture does not include preformed foam; wherein the concrete mixture is poured at a density of less than about 90.8 pounds per cubic foot.
