... was also higher, suggesting enhanced mechanical energy absorption. Scanning electron microscopy analysis revealed that the incorporation of SF improved the microstructure and high-temperature bonding behaviour. Overall, these findings indicate that HECC is a highly effective alternative to conventional...

... after chemical attack and high-temperature exposure (200–1000°C) and compared with those of Portland cement mortar (PCM). Compared with the PCM, the FA/GGBS-based AAAM showed better resistance to chemical attack and high-temperature exposure. After 180 days of acid exposure, the PCM showed a mass loss...

... rate of 10°C/min to achieve target temperatures of 200°C, 400°C, 600°C and 800°C for each group of specimens. Each target temperature was held for 40 min to ensure even heating of the specimens. A special heating subroutine was set to prevent the specimens from bursting at high temperature (300–400°C...

..., in this study, the influence of steel fibres and aggregate type on the compression and bending properties of AASCM after high-temperature treatment was investigated. The results show that the mass loss rate, compressive strength and flexural strength loss rate of AASCM with manufactured sand were higher than...

... tensile strength of concrete at high temperature is determined experimentally. The test results indicate that early residual splitting tensile strength decreases with temperature. To understand this phenomenon, temperature distribution is examined. Compared to residual tensile strength, loss of early...
