“…Spalling is defined as damage where concrete surface scales and falls off from the concrete along with explosion at a high temperature [22]. The spalling of concrete under high temperatures is a concern due to exposure of the steel reinforcement to direct fire contact and subsequent structural capacity loss of the element [7].…”

a b s t r a c tIn this study, size effect on the residual properties of Engineered Cementitious Composites (ECC) was investigated on the specimens exposed to high temperatures up to 800°C. Cylindrical specimens having different sizes were produced with a standard ECC mixture. Changes in pore structure, residual compressive strength and stress-strain curves due to high temperatures were determined after air cooling. Experimental results indicate that despite the increase of specimen size, no explosive spalling occurred in any of the specimens during the high temperature exposure. Increasing the specimen size and exposure temperature decreased the compressive strength and stiffness. Percent reduction in compressive strength and stiffness due to high temperature was similar for all specimen sizes.

“…Plain HSC and NSC) since it encountered severe explosive spalling during this study, as well as in other past studies [7,8]. The target is to develop a relationship which can be used to select appropriate organic fibre types and geometries capable of lowering the relative maximum pressures in Plain HSC from a value of 1 to an acceptable threshold value in fibre-reinforced concrete below which no spalling will occur.…”

Abstract. This paper presents results of a study which investigates spalling in small scale specimens of fibre-reinforced high strength concrete exposed to elevated temperatures. A relationship to predict relative maximum pressures was developed, which takes into account parameters such as concrete strength, fibre type and fibre geometry. Also, a blowtorch spalling test method was utilized to investigate spalling in small scale specimens, and a clear relationship between relative maximum pore pressures and spalling was observed.

“…Most concrete elements are precast using the same concrete technology in their totality (Han et al 2005;Otremba and Kessler 2009;Caratelli et al 2011). This effective methodology for guaranteeing structural safety and improving service life results in an inefficient use of resources and in greatest material costs (Otremba andKessler 2009, Dias et al 2010).…”

“…Therefore, the percolation of pores in the ITZ is of great interest for studying the transport phenomena in Portland cement-based materials Bonneau et al 2000;Care 2003;Princigallo et al 2003;Scrivener and Nemati 1996;Yang 2005;Yang and Cho 2005). By using mercury intrusion porosimetry (MIP) test, Winslow et al (1994) found that a sudden increase in intruded pore space was observed when the sand volume fraction increased from 45% to 49% (Winslow et al 1994).…”

“…These segments, must be resilient to water ingress (Franzen and Celestino 2002;Gomes 2005;Gall and Soe 2011) and to fire events (Kodur and Phan 2007;Kim et al 2010;Alonso et al 2011) under conditions of use and also to precast and sometimes unforeseen mechanized production actions (Río 2009;Caratelli et al 2011). A significant state of art design criterion, applied to tunnel segments nowadays, is to adopt not standard mix proportions involving also the use of fibres (Han et al 2005;Otremba and Kessler 2009;Caratelli et al 2011). Nevertheless, in most cases, the adoption of waterproof and/or fire sprayed additional layers cannot be avoided (Kim et al 2010).…”

Production of cement is ranking 3 rd in causes of man-made carbon dioxide emissions world-wide. Thus, in order to make concrete more sustainable one may work along one or more of the following routes; 1) Replacing cement in concrete with larger amounts of supplementary cementing materials (SCMs) than usual, 2) Replacing cement in concrete with combinations of SCMs leading to synergic reactions enhancing strength, 3) Producing leaner concrete with less cement per cubic meter utilizing plasticizers and 4) Making concrete with local aggregate susceptible to alkali silica reaction (ASR) by using cement replacements, thus avoiding long transport of non-reactive aggregate.
