Metallic fiber reinforced refractory concretes

Abstract : This paper deals with the study of the mechanical behavior in the 20 degrees C-900 degrees C temperature range of refractory concretes reinforced with metallic fibers. Fibers are introduced to improve the damage resistance and to minimize the quasi-brittle behavior of refractory concretes. In some cases, a plastic or ductile like behavior can be obtained. Two approaches are considered in these studies. The first one is based on the micromechanical scale. Main objectives are to understand, quantify and predict the thermomechanical behavior of monofiber microcomposites. Such considerations are helpful to optimize the composite formulation for a better behavior. The second one is based on the macromechanical scale. Main objectives are to characterize and to model the macroscopic thermomechanical behavior of randomly reinforced refractory concretes. A particular attention is firstly paid to the relationships between the microstructural changes and the mechanical properties and secondly to the structural size effects.
