“…Abdullah and Nilu¨fer tested the compressive strength of HPC incorporates PP fiber and air entraining admixture (AEA) subjected to elevated temperatures. They found that the collaboration of AEA and PP fiber decreases the risk of spalling of HPC (Akca and Ö zyurt Zihniog˘lu, 2013). Mugume and Takashi investigated the effect of fiber type and geometry on the maximum pore pressures of HSC exposed to elevated temperatures.…”

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.

“…Increase of the tensile stresses in the concrete structure is caused by the thermal expansion of the aggregates from 300 °C, where some cracks appearance was noted [11]. This explains the fact that only negligible decrease of the concrete mechanical parameters under 300 °C is usually observed.…”

Abstract. The effect of high temperature exposure on properties of a newly designed High Performance Concrete (HPC) is studied in the paper. The HPC samples are exposed to the temperatures of 200, 400, 600, 800, and 1000°C respectively. Among the basic physical properties, bulk density, matrix density and total open porosity are measured. The mechanical resistivity against disruptive temperature action is characterised by compressive strength, flexural strength and dynamic modulus of elasticity. To study the chemical and physical processes in HPC during its hightemperature exposure, Simultaneous Thermal Analysis (STA) is performed. Linear thermal expansion coefficient is determined as function of temperature using thermodilatometry (TDA). In order to describe the changes in microstructure of HPC induced by high temperature loading, MIP measurement of pore size distribution is done. Increase of the total open porosity and connected decrease of the mechanical parameters for temperatures higher than 200 °C were identified.

“…Numerous studies were carried out to investigate the variation of compressive strength and durability of concrete exposed to elevated temperature [1][2][3][4][5][6]. The deteriorations of physical properties, mechanical properties and durability of concrete were significantly affected by the exposure temperature.…”
