Methods and equipment for the investigation of rheological properties of complex materials like convectional brick clays and ceramic reinforced composites

In the present work two special instruments are described and introduced which were developed for the rheological tests of materials like minerals, raw materials and semi-finished products of ceramic industry or complex materials like ceramic particles and fibre reinforced metal alloys and hetero-module, hetero-viscous and hetero-plastic materials with increased dynamic strength. The working principles of introduced 'rheotesters' are relatively simple and easy for use to determine rheological parameters like instantaneous elastic modulus, delayed elastic modulus or viscosity of damaged and undamaged material structures. The instruments give the opportunity to easily and quickly prepare the rheological model of tested materials.
