a b s t r a c t A novel fire testing method, named the Heat-Transfer Rate Inducing System (H-TRIS), is presented and described in this paper. The method directly controls the thermal boundary conditions imposed on a test specimen by controlling a specified time-history of incident radiant heat flux at its exposed surface. Accounting for the absorptivity and thermal losses at the exposed surface of the test specimen, H-TRIS can be programmed to control the net heat flux at the exposed surface; thus controlling the in-depth time dependent temperature distributions within the test specimen. H-TRIS can be used for imposing a wide range of time-histories of incident radiant heat flux (e.g. constant, linear, stepped), or in-depth time dependent temperature distributions (i.e. specified thermal gradients). Notably, this enables simulation of thermal boundary conditions experienced by materials or structures exposed to any source of heatduring a conventional fire test (e.g. standard furnace test), a large-scale fire test, a real fire, or some other thermal boundary conditions calculated using a fire model (e.g. zone or computational fluid dynamics model). H-TRIS enables complementary experimental studies with excellent repeatability at comparatively low economic and temporal costs relative to traditional furnace test methods, thus permitting multiple repeat tests and statistical studies of response to heating. Application of H-TRIS within a research project studying heat-induced concrete spalling is briefly presented and discussed, to illustrate the significance and novelty of the new fire testing method.

“…The construction industry has made significant advancements in research and development, resulting in high-performance concrete mixes that exhibit enhanced microstructure and improved mechanical properties, including increased strength, toughness, and durability. Nevertheless, recent studies have revealed that these highperformance concretes do not possess equivalent fire endurance Frontiers in Materials frontiersin.org compared to traditional concrete (Kodur and Khaliq, 2011;Hulin et al, 2016;Xiao et al, 2017). Changes in the microstructure of concrete occur in correspondence with the heating process, ultimately resulting in structural failure of the concrete.…”

Recent research has shown that the incorporation of fibres, such as steel and polypropylene fibres, in concrete can significantly improve its resistance to spalling under high-temperature conditions. However, the reported outcomes of studies on the spalling performance of Fibre Reinforced Concrete (FRC) vary significantly due to differences in cementitious matrix and fibre types, mix design, and testing techniques. Existing review studies have struggled to systematically and precisely consolidate the diverse aspects of the literature. To address these limitations, this paper adopts the latest approach for mining, processing, and analyzing data to interpret bibliographic data on the fire resistance of FRC. The primary objective of this study is to comprehensively explore the viability of FRC as a fire-resistant and refractory material. In pursuit of this goal, the paper thoroughly reviews various aspects of FRC behavior at elevated temperatures, including pore pressure behaviors. Moreover, this review also discusses spalling behaviors, mechanisms, and residual mechanical properties under high temperatures. The microstructural analysis of FRC is also discussed comprehensively to gain an in-depth understanding of its behavior under elevated temperatures. By analyzing available data, this study aims to shed light on the potential of FRC as a suitable material for resisting spalling in high-temperature scenarios. Additionally, the research delves into prospects and challenges in achieving sustainable FRC with enhanced spalling resistance, considering both material and structural levels.

“…Therefore, it is theoretically possible to use HPC in joints where stress concentrations normally occur to improve the performance of concrete building structures. Previous studies (Hulin et al, 2016a(Hulin et al, , 2016bEkmekyapar and Alhatmey, 2019;Ghazy et al, 2022) have shown that HPC can improve the fire resistance of structural elements such as concrete slabs and columns. However, no studies have been conducted on the fire resistance and post-fire performance of assembled wall-slab joints using HPC.…”

In this study, the post-fire behaviour of a novel assembled wall-slab joint with high-performance concrete (HPC) post-casted in the core area was experimentally investigated. Fire and post-fire monotonic static loading tests were performed on three full-scale specimens, including two assembled joints and one cast-in-place joint for comparison. The temperature distribution inside the joints exposed to fire, failure displacement and failure mode of the joints after a fire, and residual bearing capacity of the joints are discussed. The results show that the assembled wall-slab joints are more integral than the cast-in-place joints after a fire. In addition, HPC can effectively reduce the temperature in the core area of an assembled joint exposed to fire and improve its post-fire stiffness. The failure modes of the two types of joints were also different. The residual bearing capacity of the assembled wall-slab joint after 1.5 h of heating was approximately 22.3% lower than after 1 h of heating. In addition, the residual bearing capacity of the assembled wall-slab joint was approximately 28% larger than that of the cast-in-place wall-slab joint at the same heating time of 1.5 h. In general, the assembled wall-slab joint showed better performance than the cast-in-place joint both during and after a fire.
