SELECTED PROJECTS
Our clients constantly implement won tenders for the US Army, NATO, and the UN in Poland and in the world. Below we present some of them. For security reasons, we cannot provide the names of contractors, amounts, and places of their execution.
WHAT IS IT
UHPC is an ultra-high-performance concrete that exceeds significantly the performance of conventional, high-performance, and
very-high-performance concretes and grouts, with significantly greater compressive and tensile strengths, ductility, bond strength
and durability.
UHPC is formulated from fine granular particles with a very low water-to-cementitious materials ratio, which results in a dense matrix with a discontinuous pore structure, leading to extremely low permeability.
The low permeability provides extreme resistance against water and chloride ingress,freeze-thaw damage, and chemical attack.
APPLICATIONS
UHPC is the result of nearly two decades of research and development and has been used for a wide variety of applications including bridge deck overlays, connections for precast deck panels for accelerated bridge deck replacement, precast/prestressed girders, repair of connections between precast concrete beams, steel column repairs, bridge joint header replacements, and architectural elements.
Other construction applications include but are not limited to cladding panels, blast- and impact-resistant panels, precast piles, precast columns and pylons, tunnel liners, protection against caustic environments and salt spray zones.
UNIQUE ATTRIBUTES
UHPC is all white and can be color-modified to suit project needs. It is dry packaged and can be reliably mixed with a variety of mixing equipment including ready-mix trucks for larger volume projects.
The 100% pre-blended dry mix reduces the need to measure ingredients on site and results in greater uniformity and predictability of the fresh and cured material properties.It works with a variety of time-saving placement capabilities unique to UHPC.
These capablities include direct-discharging from ready-mix trucks, flush-forming deck-level UHPC connections, curing deck overlays without covering the overlays with plastic sheeting, and pumping and spraying UHPC,
