Thermomechanical behaviour of refractory dry-stacked masonry walls under uniaxial compression

• Experimental and numerical tests on dry-joint refractory masonry walls carried out. Tests out at ambient high temperatures. Loadbearing capacity, cyclic loading thermal restrained behaviour tested. Identified effects of stress concentration caused by brick’s height imperfections. Concrete damaged plasticity model proved to be suitable in modelling. Vessels used industrial temperature processes steel cement production are protected linings built with dry-stacked masonry, which plays a crucial role the overall vessels. This paper presents results an experimental research subjected uniaxial compression. Its main purpose is fully characterize different temperatures conditions. Several aspects that may influence these have been tested, namely loadbearing under elongation. The allowed identify concentrations imperfections mechanical bricks capacity specimens, evolution wall’s Young’s modulus load application, developed crack patterns samples Numerical models were also simulate testing conditions good agreement was obtained. concrete model, using micro-modelling approach, for representing
