“…Some were conducted on small-scale specimens (mainly cylinders) (Boström et al, 2007;Han et al, 2005;Heo et al, 2010;Hertz, 2003;Phan, 2007;Phan et al, 2000) while others concentrated on building components (mostly columns and concrete blocks) (e.g. Bilodeau et al, 2004;Boström et al, 2007;Kalifa et al, 2001;Kodur, 2003;Kodur and McGrath, 2003;Park et al, 2007).…”

A state-of-the-art review of experimental and analytical studies on fire-induced spalling in concrete structures is presented. The limitations in current code provisions related to spalling are discussed. A hydrothermal-based spalling model is applied to undertake parametric studies to investigate the effect of critical parameters on fire-induced spalling in reinforced concrete beams. The results of these studies show that fire scenario and concrete permeability largely influence the extent of fire-induced spalling in reinforced concrete beams. Research needed for improving the state-of-the-art on fire-induced spalling in concrete structures is highlighted.

“…The results also showed that the boundary of the specimen had an effect on the amount of spalling. Heo et al (2010) carried out a study to optimise a combination of fibres for spalling protection of concrete in fire exposure. Various combinations of PP, polyvinyl alcohol, cellulose and nylon fibres were investigated.…”

“…Figure 35 shows that the synergistic effect of NY and PP fibers plays a crucial role in providing effective connections of pores in concrete at different thermal conditions. They also observed that concrete containing NY (length of 9 mm) and PP (length of 19 mm) fibers shows no explosion taking place even at only 0.03% of fiber content (Heo et al, 2010). Han et al studied the antispalling of HPC with PP fiber and fabric or sheet material for lateral confinement subjected to fire.…”

Smart concretes and structures are intelligent systems that have properties different from normal concrete, such as selfsensing and self-healing properties, or have the ability to react upon an external stimulus, such as stress and temperature. The ''smartness'' of concrete and structures is achieved through material composition design, special processing, introduction of other functional components, or modification of the microstructure. They are designed to meet specific requirements through tailored properties for improving serviceability, safety, reliability, longevity, and durability of the infrastructures and reducing the life-cycle costs of the infrastructures. This article reviews the recent researches of various smart concretes and structures, with attentions to their principles, fabrication, and properties. Future challenges in the development and applications of smart concretes and structures are also discussed.

“…However, UFC has been particularly susceptible to spalling in fire. Generally, the addition of synthetic fibers, especially polypropylene (PP) fiber to highstrength concrete is widely used as an effective measure to prevent explosive spalling [4][5][6]. Authors have investigated the effectiveness of adding jute fiber (natural fiber) to UFC (fc;150MPa with aramid fiber), for preventing spalling at high temperature [7].…”

Abstract. In this study, we examined the relationship between spalling behaviour and spalling ratio of UFC with three kinds of short fibers (jute, polypropylene, water-soluble polyvinyl alcohol) at high temperature. The heating temperatures were 400• C and 600• C. Although the specimen with jute fiber dosage of 0.19% by volume was occurred explosive spalling, the damage of specimen was slightly small. It appears that the addition of jute fiber to UFC is effective for preventing spalling.
