“…Petrov-Denisov et al [42] also present a theory including the rapid expansion of super heated water. According to their theory the walls between closed pores with super heated water and open pores with lower pressure can be destroyed by the pressure difference and as Hertz [43] points out this can lead to a progressive breakdown of the microstructure.…”

“…The physical changes and chemical decomposition of concrete constituents at elevated temperatures is demonstrated in widely spread cracks, explosive spalling or both. In reinforced concrete members, such changes are reflected by a reduction in the mechanical properties, increase in the permeability of concrete, and weakening of the bond strength between embedded steel and concrete [10][11][12]. Many studies have been carried out to investigate the effect of the elevated temperature on different concrete specimens [13][14][15].…”

Concrete materials in structures are usually exposed to high temperatures during fire. The relative properties of concrete after such an exposure are of great importance in terms of the serviceability of buildings. The effect of partial replacement of cement with pulverized steel mill scale (PSMS) on the compressive strength of concrete cubes was investigated in the first test. Furthermore, the influence of elevated temperatures on the compressive strength of the concrete cubes with cement partially replaced with PSMS was examined. For the second test the cubes were exposed to elevated temperatures ranging from the ambient temperature to 750°C in steps of 250°C for 2 hours and allowed to cool for 24 hours. Based on results of tests, partial replacement of cement with 10 % PSMS is recommended for use in concrete production and resistance to elevated temperature. The studies show that at this replacement, the concrete compressive strength is not adversely affected when the elevated temperature reaches 500°C.

“…Hertz performed a comprehensive literature study of different available theories that explain the spalling phenomenon and concluded that the formation of vapour inside the concrete is the most important factor [6].…”

Abstract. As the loss of concrete cover can significantly influence the reliability of concrete elements during fire, spalling should be taken into account when performing reliability calculations. However, the occurrence and spatial variation of spalling are highly uncertain. A first step towards a probabilistic analysis of spalling is made by combining existing deterministic models with a stochastic representation of the concrete tensile strength and by using random fields to model the tensile strength spatial variation.
