This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...

Flish sediments represent atypical raw materials: marls, marly shales and shales. This paper presents the results of laboratory tests of shales. The paper points out the similarities and differences in technological ...

The aim of this paper is to establish the correlation among sintering process, porosity, and important thermo-mechanical property of refractory concrete, i.e., creep. Creep deformation was investigated according to the ...

The paper briefly reviews results of laboratory testing performed in order to establish the possibility of adopting the process of production of solid bricks from plastic clay and fly ash. The experimental results substantiated ...

The brick industry development trends have two main directions: high product quality and use of lower quality clays and secondary (recycled) raw materials, The development trends reflect today's market requirements - ...

Anionic clays are becoming more important for their application as catalysts, ion exchangers and adsorbers and for medical applications as well. Anionic clays are also used as stabilizers of dispersive systems of ceramic ...

This paper is concerned with quantitative formulation of the mechanism of the sintering process during secondary state creep deformation of refractory concretes. Investigated concretes varied in, both, chemical and ...

in order to gain the benefits of weldable high-strength steels in pressurized equipment applications, satisfactory toughness and crack properties of the welded joint, both in the weld metal and the heat-affected-zone (HAZ), ...
