Glued timber concrete composite walls using ultra-high-performance concrete
Acta Polytechnica CTU Proceedings, 2022 This paper gives a short introduction of the development of cross laminated timber (CLT) concrete composite walls with a glued connection. In the composite walls, prefabricated ultra-high-performance concrete (UHPC) lamellas replace timber lamellas at ...

Ultra-High-Performance Concrete Shear Keys in Concrete Bridge Superstructures [PDF]
MATEC Web of Conferences, 2019 Many existing bridges have adjacent girders that utilize grouted shear keys to transfer loads laterally across the superstructure. Cracking and leaking often cause degradation of the shear key and the girder.

Concrete spall damage of UHPC slabs under contact detonation - An experimental investigation [PDF]
, 2015 Concrete spallation is a typical brittle damage mode under close-in or contact explosions. Upon concrete spallation, a large number of fragments displace from the concrete surface with high speed and these fragments endanger the personnel and equipment ...

Mechanical and fracture properties of a self-compacting version of CARDIFRC Mix II [PDF]
, 2017 CARDIFRC is the trade name of two main groups of ultra-high performance fibre-reinforced concrete mixes – Mixes I and II – differing primarily in the maximum size of quartz sand used (0.6 mm in Mix I, and 2 mm in Mix II). In this paper, the conversion of

ULTRA HIGH-PERFORMANCE CONCRETE BEHAVIORAL STUDY
Journal of critical reviews, 2022 It is investigated in the study paper how UHPC reacts when used as a bridge girder material. The early-age shrinkage, transfer length, creep behavior, and shrinkage following steam treatment of four optimized girders were all investigated. Data was gathered using vibrating wire gauges at strategic locations inside each girder after re casting.
