  • formulating the cement mix using the composition of the present invention while limiting the addition of water such that the concrete mix is low-slump or no-slump, as described in US 8,959,862, permits the vibration of the freshly-poured concrete without causing an increase in density.
  • tilt-up panels In tilt-up construction, a building's walls are poured horizontally directly at the jobsite in large slabs of concrete called “tilt-up panels” or “tiltwall panels” . These panels are then raised into position. Because of the stress placed on the panel during hoisting from a horizontal to a vertical position, it is necessary to lightly vibrate the freshly poured concrete to eliminate large voids, which might weaken the panel and cause it to break during hoisting. Thus, the present invention provides for wall panels that are integral and unitarily formed without seams. Because prior art (e.g., SACON®) methods have large voids which make the concrete weak, prior art structures cannot be moved for at least about 14 days, thus making tilt-up construction methods impractical. In contrast, the microscopic voids and fiber of the present invention allow structures manufactured according to the present invention to be moved after about 24 hours. Thus, the present invention provides for the more economical manufacturing of ballistic panels than prior art methods.

  • using larger paver blocks means fewer blocks to move and adhere to the wall.
  • larger ballistic paver blocks create fewer seams, which is desirable because a bullet may penetrate a seam more easily than a non-seam section of the ballistic paver block.

  • the ballistic paver blocks are made with ballistic concrete prepared in some other manner where the ballistic concrete is used to allow bullets to be captured rather than ricochet off of the ballistic paver block when striking the paver block substantially perpendicularly.
  • the adhesive is placed only on the singular face of each individual ballistic paver block that contacts the preexisting wall or previous layers of ballistic paver blocks. In this configuration, the adhesive is used to ensure the ballistic paver blocks do not slip away from the wall. The combined weight of the ballistic paver blocks is transferred down to the floor and therefore no adhesive on the bottom of the ballistic paver blocks is required. In another embodiment of the present invention, where the shape of the augmented wall warrants it, adhesive can be applied to every side of the ballistic paver blocks.
  • a bullet resistant wall with three layers of 30 x 30 x 7.6 cm (12 x 12 x 3 inch) ballistic paver blocks with offsetting vertical and horizontal seams was shot repeatedly with a NATO M80 round (7.62 NATO) using an Armalite AR-10 rifle with a 20 inch barrel. The shots were filed substantially perpendicular to the augmented wall. The distance from the gun to the wall was well under 25 m (82 feet) and is thus unimportant as the velocity of such a bullet is constant for the first 25 m (82 feet). The depths of penetration of the bullets measured from the outermost ballistic paver block to the trailing end of the projectile were in the range of 2.5 to 7.6 cm (1-3 inches). This is a small fraction of the 23 cm (9 inch) total depth of ballistic paver blocks according to this embodiment of the present invention, so a second shot that hit the same bullet hole would not be able to traverse the ballistic paver blocks.
  • the edges of the ballistic paver blocks are beveled.
  • the vertical edges of the ballistic paver blocks are cut at a 45 degree angle to form beveled edges.
  • Blocks are juxtaposed with alternating bevels to form a bevel joint, in order to eliminate gaps.
  • FIG. 14 illustrates an example embodiment of blocks with two beveled edges fitted together according to the present invention.

  • the injector assembly outlet 290 is aligned with an opening in faceplate 140 to allow injection of a slurry of replacement material into the void 108.
  • STEP 1504 Prepare the void 108 for repair. Using rubber gloves (and trowel as appropriate), clean out the void, removing any loose material. Ballistic concrete contains fiber material and there will be fibers extending into the cleaned-out void from the ballistic panel. These fibers may be left as is. Fibers remaining in and around the void 108 will help the replacement material to bind to the existing material in the ballistic panel.
  • vent hole 312 could be drilled above the top edge of the faceplate 140. While a single vent hole 312 may be sufficient for many applications, those of skill in the art will recognize that the process may include more than one vent hole, especially for a larger or irregularly shaped void.
  • a small injector assembly 200 that does not weigh an undue amount relative to the stiffness and length of the injector assembly may be operated without a support beam.
  • Step 2036-Remove the Outlet Valve Once the replacement material in the outlet valve 212 has set up sufficiently, unthread the outlet valve 212 from the second steel nipple 278. Clean the outlet valve 212 thoroughly.
  • Step 3012 Provides the Vent Hole. Likewise, remove any protruding material from the vent hole 312 and work the area to provide a smooth surface. Any holes from the fasteners 308 in the ballistic panel 104 can be filled with replacement material at this time.
  • Step 3024-Cover the Repaired Area Place plastic film over the repaired area and seal with duct tape to hold in the moisture on the repairs. Expect to see condensation on ballistic panel side of the plastic film.
  • Step 3028-Mark the Area with a No-Shoot Indicator For example, one might use bright red tape or other warning tape to mark the perimeter of the area to indicate that the repaired area should not be shot and should not be behind a target that is used. A date may be written on the tape along with a unique identifier for the test cylinder in case there are many different repairs and different test cylinders.
  • Both injector assembly 200 and injector assembly 1200 have a cap 204 or 1204 located above a line running between the inlet valve 208 and the outlet valve 212 or 1212.
  • the upper portion of the injector assembly serves as a reservoir for replacement material.
  • the present invention does not require that the upper portion of the injector assembly 1200 be oriented in a pure vertical orientation. Filling the injector assembly 1200 with a quantity of replacement material works well as long as the upper portion has a substantial vertical orientation.
  • a push-pull actuator with two handles on either side of the outlet valve 1212 may be advantageous for use as the actuator 1286. Placement of the push-pull actuator such that the outlet valve 1212 is closed when the actuator 1286 is in the up position allows downward pressure against the pressurized replacement material which may be the more difficult change in valve position to be done with the least risk of dislodging the injector assembly from the support beam 150. Horizontal orientation for the push-pull actuator may be implemented if additional caution is used to avoid pushing the injector assembly 1200 off the support beam 150. An injector assembly/support beam interaction that would keep the injector assembly 1200 supported even after some horizontal movement of the inlet end 160 of the injector assembly 1200 may be acceptable.
  • FIG. 22 may have a total height of approximately twenty inches from the lower actuator 1286 to the top of the cap 1204 (excluding the camlock).
  • compressed air is a well-known item for use in construction sites including remote sites as air compressors are made with a variety of fuel options and tanks of compressed air are easy to carry to a remote site, the process does not require that the compressed gas be air.
  • Other gases can be used providing that they are compatible with the replacement material (won't alter the replacement material) and safe for use around those performing the procedure.
  • injector assemblies 200 and 1200 show an inlet approximately horizontal with the outlet, this is not a requirement.
  • a pressurized gas inlet could be placed out of horizontal alignment with the outlet.
  • an injector assembly inlet could be placed above the outlet. The inlet could even be placed above the removable cap.
