Transportation Infrastructure (Automobile, Rail, Maritime)
Precast UHPC Components
Precast UHPC components for bridges, tunnels, piers, wharfs and their foundations are lighter, stronger, and dramatically more durable than conventional concrete components. This means reduced foundation costs, reduced transportation costs, and dramatically reduced maintenance and lifecycle costs. These can also be employed to accelerate construction without sacrificing durability, as in accelerated bridge construction (ABC), especially when paired with UHPC closure pours.
Examples of precast UHPC components are beams and girders, deck panels, piles, retaining wall and seawall panels, and tunnel lining.

Field-Cast UHPC Components
Field-cast UHPC components for transportation infrastructure provide all the same benefits as precast UHPC including dramatically greater strength and durability and lighter weight depending on the specific application, but with the flexibility of on-site casting.
Examples of field-cast UHPC components are link slabs, to retrofit deck structures by eliminating expansion joints, tunnel lining, and connections between precast elements. UHPC connections can connect precast elements made of conventional concrete or UHPC, providing connections that are very compact and as strong or stronger than the elements being connected, both in terms of strength and durability. Precasting structures can accelerate on-site construction, but historically the connections have been weak points where cracking and deterioration begin but using UHPC for the connections eliminates the weak points.
Examples of precast components that can be connected with UHPC include deck panels, approach slabs, girders, abutments, columns, bent caps, retaining wall and seawall modules, and tunnel lining modules.

Field-Cast UHPC for Preservation and Repair
Using UHPC to preserve and repair existing transportation structures can dramatically extend the service life of the structures for just a fraction of the cost and out-of-service time of replacement. By significantly delaying structure replacement, UHPC minimizes the structures carbon footprint, serving as an important environmental sustainability tool. And applications are not limited to concrete structures. The UHPC can be applied with several methods, either poured with a self-consolidating consistency, screeded or troweled with a less flowable consistency, or sprayed a.k.a. shotcrete.
Applications of field-cast UHPC for transportation infrastructure preservation and repair include:
- Concrete deck rehabilitation for protection or strengthening (deck overlay)
- Link slabs for expansion joint elimination
- Repair of steel girder ends
- Replacement of expansion joint headers
- Repair of existing connections between precast elements
- Strengthening of existing steel girders
- Seismic retrofitting of columns
- Concrete column and pier repair and protection
- Steel column and girder repair and protection
- Concrete element patching
- Repair of culvert and tunnel structures

Building Infrastructure
(high-rise, low-rise, industrial, and parking structures) Precast UHPC Components
Precast UHPC components for buildings, factories, and parking structures and their foundations are lighter, stronger, and dramatically more durable than conventional concrete components. This means reduced column and foundation costs, reduced transportation costs, and potentially dramatically reduced maintenance and lifecycle costs. These can also be employed to accelerate construction without sacrificing durability for parking structures and aggressive industrial environments.
Examples of precast UHPC components for buildings are shear walls, wall panels, modular building units, beams including double-tee beams, balcony slabs, cladding and facade panels, and piles.

Field-Cast UHPC Components
Field-cast UHPC components for building infrastructure provide all the same benefits as precast UHPC including dramatically greater strength and durability and lighter weight depending on the specific application, but with the flexibility of on-site casting.
Examples of field-cast UHPC components are ultra-high strength columns, beams, slabs, slabs on grade, foundation walls and waterproofing, and connections between precast elements. UHPC connections can connect precast elements made of conventional concrete or UHPC, providing connections that are very compact and as strong or stronger than the elements being connected, both in terms of strength and durability.

Energy Infrastructure
Nuclear
UHPC is much more dense than conventional concrete, allowing it to provide the same radiation shielding with much less material. As with conventional concrete, UHPC can also be modified with mineral additives to increase its shielding abilities and maintain its advantage of conventional concrete.
Energy Infrastructure
Wind
With the high strength and extreme durability of UHPC, precast UHPC shells have been shown to be a viable alternative to steel wind turbine towers, with virtually no maintenance required.
In addition, the strength and durability of UHPC makes it well suited to grouting connections at the base of wind turbine towers, especially off-shore towers where durability is critical.

Energy Infrastructure
Hydropower
The extreme durability of UHPC including wear resistance make it ideally suited for the lining of dam spillways and other high-flow conveyance components, for either new construction or to repair existing structure.
Energy Infrastructure
Petroleum
The strength and extreme durability of UHPC make it well suited for multiple application within the petroleum industry. For offshore oil platforms, UHPC has applications for protecting, repairing, and strengthening platform structures.
In refineries and oil conveyance infrastructure, UHPC can provide wear and corrosion protection.
Finally, UHPC is well suited for use as an oilwell cement for lining drill holes and plugging abandoned holes.
Architecture
The extremely fine-grained nature of UHPC, along with its strength and durability, make it ideally suited to many architectural applications. UHPC can flow through very tight spaces and will assume the shape of even the most detailed formwork, creating endless opportunities for shapes and surface patterns.
Steelike UHPC is all-white, which allows it to be color modified to virtually any color imaginable. Steelike’s technology enables completely encapsulation of fibers, so no fibers are exposed at the surface, eliminating the corrosion of steel fibers at the surfaces and allowing the incorporation of steel fibers in architectural elements. These attributes make Steelike UHPC even better suited to architectural applications than other UHPC products, many of which are grey and require the use of weaker non-metallic fibers to avoid surface staining from fiber corrosion.
- Examples of architectural applications of UHPC include:
Building cladding / facade panels/ rainscreens - Retaining wall panels
- Sound wall panels
- Architectural staircases
- Urban furniture
- Decorative tiles
- Sculptures
Security and Defense
The density and strength of UHPC make it an ideal material for security and defense applications. For the same thickness, the resistance of UHPC against concentrated and explosive loads is many times higher than the that of conventional concrete.
Examples of security and defense applications include:
- Blast- and impact-resistant walls
- Security bollards and barriers
- Military force protection
- Electromagnetic Pulse (EMP) resistance
