In this paper it is presented the analize of the effect of magnetite aggregate on the microstructure of shielding concrete exposed to an elevated temperature. Two shielding concretes containing magnetite aggregate and concrete containing normal aggregate have been tested. Samples were exposed to 300, 450, 600 and 800 °C. In order to characterize changes in the microstructure of concretes, samples have been tested with use of scanning electron microscope (SEM) and X-ray diffraction (XRD) techniques. Presented studies have shown that magnetite aggregate has influence on the microstructure of concrete subjected to an elevated temperature.

Keywords: heavyweight concrete, shielding concrete, microstructure, high temperature.
