Ultra-High Performance Concrete and High Performance Construction Materials
2020Ultra high performance concrete (UHPC) is known for its high compressive strength of more than 150 MPa and its high durability. Thermal treatment at 90°C can accelerate the strength development so that the 28-days-strength can be achieved immediately after the treatment and an additional increase up to 30 % in some cases.

Interface strength of High-Strength concrete to Ultra-High-Performance concrete
Engineering Structures, 2022Abstract High-Strength Concrete (HSC) has been used in the production of precast concrete structures while Ultra-High-Performance Concrete (UHPC) has been considered an option for filling the connection between HSC elements due to outstanding mechanical properties and durability.

Rehydration of Ultra High Performance Concrete
Advanced Materials Research, 2014Ultra High Performance Concrete (UHPC) and High Strength Concrete (USC) are because of the high density of their matrices very susceptible to spalling during fire exposure. By aid of a heat treatment with maximum temperatures of about 450°C a network of capillaries and micro cracks could be formed, which leads like a porous medium to a relief of water ...

Durability of Ultra-High-Performance Concrete
SP-261: 10th ACI International Conference on Recent Advances in Concrete Technology and Sustainability Issues, 2009This paper describes how ultra-high-performance concrete (UHPC) has gained more interest in the concrete construction industry in recent years due to the expected high durability of UHPC, as well as extended architectural opportunities. Compared to normal concrete it is possible to build filigree and lighter structures with ultra-high-performance ...
