Highlights UHPC is recently becoming an ultimate candidate for concrete in the construction market. UHPC has a low fire resistance due a dense microstructure and a low permeability coefficient. This article reviews the fire-spalling mechanisms, influencing factors, and mitigation strategies of UHPC. This review will help in providing insights to benefit specialists to improve the existing design guidelines. Further research requires to consider fire-induced spalling of UHPC in the current fire design codes.
Abstract 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 employing UHPC is that is very low permeability owing to its great compactness of dense structure increases the risk of fire-induced spalling. It is challenging for fire safety and structural engineers to predict and analyze this issue due to the lack of widely accepted and reliable models for concretespalling. Therefore, understanding the fire-spalling characteristics of UHPC exposed to high temperature or fire is vital for ensuring the safety of a UHPC-based structural fire design. To date, the fire-induced spalling behaviour of UHPC has not been thoroughly investigated. To address this informational gap, this article aims to assess various aspects of UHPC by focusing on fire-induced spalling and its influencing factors, spalling mechanism, microstructure characterization, prevention measures, and mitigation strategies. Moreover, this critical review summarizes and evaluates the results of thermal spalling tests and fire-induced spalling modeling undertaken on UHPC in developing a manual regulation protocol. This paper aims to provide insights into improving the existing design guidelines for the fire-spalling-resistant design of UHPC members, this facilitating wide-scale adoption of robust and sustainable UHPC. Given the merits of the study topic, the review strategies and initiatives can then be leveraged to give insight into areas that will be highly beneficial for future experiments and research of UHPC applications by research centers and construction industries globally.
