The utilization of urban underground space (UUS) offers an effective solution to urban
problems but may also negatively affect urban development. Therefore, UUS development …

Ultra-high performance concrete (UHPC) is a novel concrete class characterized by a
compressive strength of more than 150 MPa. One of the most significant drawbacks of …

This research paper presents the first scientific attempt at a comparative study of thermal
resistance of fly ash based geopolymer concrete and rubberized geopolymer concrete. In …

Segmental joints act as a weak link in the tunnel lining both in terms of structural responses
(due to the lower stiffness and strength compared to the main segments) and the …

When exposed to fire, the integrity of cement-based materials is governed by thermally-
induced changes in the mechanical properties of their binding phase, ie, the calcium …

There are no available guidelines or methodologies to design the concrete lining in a tunnel
for loss of functionality following a fire event. Historical tunnel fires confirm that tunnel …

Lightweight aggregate high-strength concrete (LWA-HSC) exposed to high temperatures
usually exhibits the poor resistance to the deterioration properties of materials, which would …

Ultra-high-performance concrete (UHPC) surpasses normal strength concrete in
engineering properties such as durability under extreme conditions, strength, and ductility …

This paper aims at developing an efficient numerical model to numerically reproduce the fire-
induced spalling process taking place in concrete and to investigate the underlying …

Ultra-high performance concrete (UHPC) is vulnerable to high temperature-induced damage
due to its dense microstructure. To mitigate thermal damage of UHPC, this study develops …
