Characterisation of mortarless refractory masonry joints under elevated temperatures

چکیده
Refractory linings are commonly employed in Industrial vessels used high-temperature processes to protect them against extreme working environments. The lining of an industrial steel ladle frequently employs mortarless refractory masonry contain the molten and limit heat losses. Such undergoes high thermomechanical loads, primarily due thermal expansion arising from mechanical boundary conditions. Dry joints, described as a physical break continuum, reduce some these effects. Therefore, understanding dry joints is essential factor for developing numerical constitutive models that employ meso or macro modelling approach. This work aims experimentally investigate normal compressive behaviour masonry. For this purpose, various specimens alumina-spinel material tested ambient temperature 1200 °C. results obtained experiments then identify critical joint parameters with different mathematical interface. outcome describes exponential closing respect force applied. It was observed pressure required close reduces increase temperature. model numerically simulate closure Finally, experimental were compared.

Cyclic Behavior of Mortarless Brick Joints with Different Interlocking Shapes
The framed structure infilled with a mortarless brick (MB) panel exhibits considerable in-plane energy dissipation because of the relative sliding between bricks and good out-of-plane stability resulting from the use of interlocking mechanisms. The cyclic behaviors of MB are investigated experimentally in this study. Two different types of bricks, namely non-interlocking mortarless brick (N-IMB...
متن کاملVoid nucleation at elevated temperatures under cascade-damage irradiation
The effects on void nucleation of fluctuations respectively due to the randomness of point-defect migratory jumps, the random generation of free point defects in discrete packages, and the fluctuating rate of vacancy emission from voids are considered. It was found that effects of the cascade-induced fluctuations are significant only at sufficiently high total sink strength. At lower sink stren...

AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...
