Research on Dynamic Compressive Performance and Failure Mechanism Analysis of Concrete after High Temperature and Rapid Cooling

Materials, Год журнала: 2022, Номер 15(13), С. 4642 - 4642

To investigate the dynamic compressive properties of concrete after high temperature and rapid cooling, an experimental study was carried out by considering five temperatures four strain rates. The coupling effect rate on damage morphology mechanical parameters comparatively analyzed. main conclusions are as follows: is affected development trends significant variability under different conditions. As increases, stress elastic modulus gradually increased. increase in reduced rate. For 20 °C 800 °C, 38.69% 7.78%, respectively. Meanwhile, SEM CT scanning technology were applied to examine mechanism from microscopic perspective, corresponding constitutive model proposed.

Abstract In this exploratory research, PET fibre and silica fume were practised for the intensification of commonplace concrete. was at dissimilar proportions 0%, 0.25%, 0.50%, 0.75%, 1.0%, 1.25% & 1.50%, while 2.5%, 5.0%, 7.5%, 10.0%, 12.5% 15.0%. practising research work in efficient manner purest form both kinds constituents purchased from India-Mart physical chemical composition details provided by them. Then several samples prepared depending upon proportion fume. all samplings examined resistance against compressive loads, tensile flexural quality fibre-Silica based modified concrete its water absorption. The outcomes load application test reveals that with usage most significant value attained 15 % practice utilized combination fibre. particular case most, gotten 15% These mainly due to highly reactive nature it reacts cement a more leads improved outcomes. loads similar maximum cases 1.25 It high strength rebound hammer UPV examination best optimum results

The Effect of Elevated Temperatures on the Behavior of Concrete Material

International Journal for Research in Applied Science and Engineering Technology, Год журнала: 2023, Номер 11(2), С. 730 - 733

Abstract: The purpose of this study was to provide an overview the effect elevated temperature on behavior concrete materials. effects temperatures properties common portland cement concretes and manufacturing materials are summarized. conventional concrete, GGBS BFS is considered performance compared with strength concrete. Concrete in case unexpected fire, will change after fire. building must be designed withstand high also mainly When exposed temperatures, such as during a mechanical strength, modulus elasticity volume stability significantly reduced. structure it degrades many different ways, color, compressive elasticity, affects density surface appearance
