Past and future of concrete in security and military

In the past there have always been interesting
safety solutions with concrete.
Some were successful, some were not. A
success story were bunker structures
underground or above ground for the navy, air
force and army. Even today, concepts for
military and civil security rooms are carried
out with concrete structures.
The next generation in which concrete is
replaced by Ultra High Performance
concrete, or UHPC for short, has been used
very successfully worldwide for a few years.
These UHPC security concepts resist the
strongest attacks, penetration is almost
impossible with the current known weapons.
UHPC security concepts are also increasingly
used in the civil construction industry for
security constructions in safes and security
rooms, coastal protection, fire protection, storm
protection, disaster protection and terrorism
protection.
We are constantly developing UHPC for new
applications, such as floating, unsinkable
platforms that can be used anywhere in the
world, both civil and military.

UHPC - The ultimate protective armor

The article was published under the title "smart material" in the journal economist several years ago

http://www.economist.com/node/21548918

We have more than 25 years of experience
in the development, production and application of UHPC Ultra High Performance concrete materials in hundreds of different applications, including in the military sector.

This article is already several years old. The development of UHPC Ultra High
Performance Concrete materials has been advanced since then.

Whereby in this case of application for
military bunker or shelter systems
the UHPC material is important, but also the

intelligent combination with other materials
and finally the installation of this material
combination.

With such different UHPC material
combinations, it is possible to dramatically
reduce the impact of a wide variety of
weapon systems.
With UHPC materials it is possible to
produce effective protection systems
in any climatic environments.

 This is a article which I found in the magazine ECONOMIST about the use of "Smart Concrete" in the militaryrld.


UHPC for military use


Safeguards whether for civilian or military objects to protect against bombings, terrorist or military attacks are always current.

We distinguish in stationary safeguards such as airfields, messages, data centers, headquarters, supply centers, etc., and mobile systems for protecting people, military equipment we e.g. properties, observation posts, etc. in international use.

Due to their unique properties UHPC Ultra High Performance Concrete can hereby assume a large part of these tasks. UHPC concrete can be combined with virtually all materials. From these combinations, we can create unique technically properties.

A little story from the past
Many years ago it was asked if we could cover the floor of a barracks with UHPC, because we would have a "super concrete". The local situation was that due to the movement of the tank tracks, the standard concrete was nearly crushed in a short time and it can always be repaired, which were crushed even faster. So that the floor area holds at least a while, the steel chains of the tanks were exchanged for tank tracks with a hard rubber coating.
The damaged floor area was jointlessly grouted with a UHPC soil material of the hardest grade in a special process. After two days, the tanks could roll again.
After several months, I asked if the commander are now satisfied that they no longer need to change the tank tracks. Surprisingly, the commander was not satisfied. He found out that he has been driving very hard on the new lined area, that causes the tank tracks to wear very quickly because now the ground is harder than the tank tracks. Now he has to go back to the tanktracks with hard rubber.
We were just too good.


Advantages:
  • Extreme high compressive strength 200 – 300 MPa (29000 - 43500 psi)
  • In conjunction with intelligent reinforcement, the strength can be increased many times over.
  • UHPC constructions are able to absorbs heavy blasts
  • UHPC structures with the same wall thicknesses than standard concrete can give 4 times more security
  • UHPC have extremely high early strengths compare to standard concrete
  • UHPC is high temperature resistant, up to 1.200°C/2192°F
  • Seawater resistant
  • Precasted constructions with very high dimensional accuracy
  • Significant improve resistant to penetration from high velocity fragments
  • High wear and corrosion protection 
  •  

UHPC protection systems are used as

Firearms protection
 - Guns with differend calibers*
 - Pistols with differend calibers*
   *Ammunition: full metal jacket bullet, hollow piont bullet, expanding bullet, high velocity bullet

Splitter proof wall construction
 - Protection from car bombs in close range, handgranates, small and medium explosions

Floor systems
 - UHPC floor and pavement systems with extreme resistance to mechanical wear of 
   heavy chain vehicles in motion.

Military bunker and shelter system
 - Special UHPC in combination with special aggregates and reinforcement is extreme
   high impact resistant against any bomb attac.
