Influence of polymer modification on the microstructure of shielding concrete
Abstract
In this paper an analysis of the influence of polymer modification on the microstructure,shielding properties against neutrons, and compressive strength of heavy-weight magnetiteconcrete is carried out. The modifications involve the addition of acrylic or epoxy dispersions aswell as micro- or/and macrofibers. A computer image analysis method is used to evaluate themicrostructure of concretes and parameters of pore structure are calculated; these parametersinclude relative volume fraction, relative specific surface area, and pore arrangement ratios,including a proprietary ratio based on Voronoi tessellation. An assessment of significance ofdifferences between stereological parameters of reference concrete and polymer modified concretes,as well as the impact of polymer form (dispersion or fibers) on shielding properties and compressivestrength is carried out using Student’s t-test. The results show that except for the effect of theaddition of both polypropylene micro- and macrofibers on the relative volume of pores, all othermodifications result in statistically significant changes in the values of stereological parameters.Nevertheless, it is shown that neither polymer dispersions nor fibers have a statistically significantimpact on shielding properties, but that they do influence compressive strength.
