A method for creating a bullet absorbing structural component made from ballistic concrete, the method comprising:
- the bullet absorbing structural component comprising:
- (i) about 1 part by mass Portland cement;
- (ii) about 0.5 to 1.5 part by mass fine aggregate;
- (iii) about 0.005 to 0.15 part by mass fiber;
- (iv) about 0.005 to 0.05 part by mass calcium phosphate;
- (v) about 0.005 to 0.05 part by mass aluminum hydroxide;
- and
- (vi) about 0.0005 to 0.05 part by mass air entrainment additive;
- such that the bullet absorbing structural component is capable of stopping a live-fire test of an M855 round with a bullet fired from an M16A2 rifle at a distance of 82-ft with a penetration depth of between 1 and 5 inches as measured to a back of the bullet from a point of bullet entry on the bullet absorbing structural component.
A method for creating a bullet absorbing structural component made from ballistic concrete, the method comprising:
- obtaining a grout of Portland cement, fine aggregate and water in a mixer;
- adding chemical air entrainment additive;
- adding fiber to the grout;
- mixing until the wet density of the grout falls within a desired density range for use in a bullet absorbing structural component for use with weapon using a particular round with a bullet fired from a particular distance so that a back edge of a bullet from a round fired perpendicularly towards a cured bullet absorbing structural component is within a range of 1 inches to 5 inches as measured from a point of bullet entry on the bullet absorbing structural component.
A method for creating a bullet absorbing structural component made from ballistic concrete by combining multiple components in a mixer, the method comprising:
- obtaining a grout of cement, fine aggregate and water in a mixer;
- adding chemical air entrainment additive without adding foam;
- forming the bullet absorbing structural component by mixing until the wet density of the grout falls within a desired density range for use in a bullet absorbing structural component;
- and
- wherein the bullet absorbing structural components are poured with a maximum depth of more than 6 feet while in a mold.
A method for creating a bullet absorbing structural component made from ballistic concrete, the method comprising:
- forming the bullet absorbing structural component by combining multiple components in a mixer, comprising:
- (i) approximately 1 part by mass cement;
- (ii) approximately 0.5 to 1.5 parts by mass fine aggregate;
- (iii) fiber;
- and
- (iv) approximately 0.0005 to 0.05 part by mass air entrainment additive without adding aluminum;
- wherein the bullet absorbing structural components are made with a maximum pour drop of the ballistic concrete exceeding 6 feet.
A method for creating a bullet absorbing structural component made from ballistic concrete by combining multiple components in a mixer, the method comprising:
- obtaining a grout of cement, fine aggregate and water in a mixer;
- adding chemical air entrainment additive without adding foam;
- adding fiber to the grout;
- forming the bullet absorbing structural component by mixing until the wet density of the grout falls within a desired density range;
- and
- wherein the bullet absorbing structural components are made with a maximum pour drop of the ballistic concrete exceeding 6 feet.
