AbstractAbout AuthorsReferences
The paper studies the influence of polyfunctional admixture based on multi-walled carbon nanotubes (MWCNTs) dispersion in combination with nanosilica (NS) on the structure and properties of gypsum cement pozzolanic binder (GCPB). The percentage of polyfunctional admixture varied. The results of the physical and mechanical tests have shown that adding polyfunctional admixture at the amount of 0,006% (MWCNT) and 10% of NS-85 from Portland cement to gypsum cement system leads to the increase of compressive strength by 52% and water resistance by 35%. Physical and chemical methods of the study have confirmed that polyfunctional admixture is reactive concerning the original gypsum cement pozzolanic binder changing the intensity and shifts of the absorption lines in the IR spectra.
