Uhpc is an emerging material technology in which concrete develops very high compressive strengths and exhibits improved tensile strength and toughness.
However, according to the literature review, very few construction joint strengthening methods have been proposed.
For this project, uhpc called k-uhpc, which was developed by the korea institute of civil engineering and building technology, was used for construction of the hawkeye bridge in buchanan county, iowa.
The advantages of the scf-uhpc include excellent axial load-bearing capacity, good ductility, and stable residual load-bearing capacity.

What makes the production of UHPC so efficient?
The production of UHPC often uses thermal curing at 90 °C or higher, vacuum mixing, and pressure before and during the setting. Although these technical procedures are beneficial to mechanical properties of UHPC, they can result in low production efficiency and high energy consumption [11].
Which is ultra high performance concrete ( UHPC )?
Ultra-High-Performance Concrete (UHPC) is an advanced type of concrete in the Civil Engineering industry. It is a cement-based composite which not less than 7 MPa. desired UHPC. For this, it is vital to understand the principles of UHPC.
What are the theoretical principles of UHPC concrete?
