| Abstract. | In order to determine the effect of carboxylic acids and their mixtures on the interaction model of media with a cement-sand mortar conducted a comprehensive study of these processes. By IR spectral analysis revealed that after the interaction of a model medium with samples of the cement-sand mortar, the intensity of the reflections of the characteristic bands is significantly reduced, indicating that the changes occurring in the model environment. In addition to study of the processes we have carried out X-ray study of a series of samples before and after the CSG test in a model environment. For this purpose, studied X-ray components that make up the CSG, CSG samples before and after exposure to biologically active and modeling environment. The x-ray samples of CSG before the interaction with aggressive media found portlanit reflection and the absence of reflections of calcite. In turn, the diffraction patterns after exposure to the CSG and BAM model environment there are reflections of calcite and very weak portlandit reflections. The appearance of the X-ray reflections of calcite in the case of interaction with environments suggests ongoing processes of change of phase of CSG. Despite the difference in the intensities of reflections of calcite after BAM testing in the aeration tanks in a model environment in the lab, we can conclude that the identity of the running processes of interaction of the investigated material with BAM and modeling environment, which is confirmed by the similarity of the diffraction patterns of phase composition. |
