About
DESCRIPTION:
The aim of the work is to assess the volume stability and thermo-elastic properties of composite materials with cement matrices and to identify models for their prediction in the field of temperature and gamma irradiation.
The elastic properties and thermal expansion of composite materials depend primarily on the volume fraction of the components and their individual properties, provided that the interfacial bonds remain stable. The degradation phenomena in the contact areas of the mineral filler grains with the multiphase inorganic matrix of the composite, appearing as a result of chemical reactions and related physical phenomena, may cause macroscopic changes in the properties of the composite. Therefore, in-depth characterization of materials requires the development of a method of predicting the effects of corrosive interactions of constituents and environmental actions, in particular by identifying experimentally the parameters of models describing the kinetics of material degradation phenomena.
The research is financially supported by Polish National Science Centre (PRELUDIUM 2023/49/N/ST8/02157).
