AbstractAbout AuthorsReferences
The investigation results of physical and mechanical properties and structure of gypsum samples modified by single-wall carbon nanotubes (SCNT) together with other additives – Portland cement, microsilica and metakaolin (HMK) are given. When analyzing the results of mechanical tests, it was demonstrated that when applying the additive complex containing carbon nanotubes and ultrafine additive the improved mechanical characteristics are observed in opposition to the application of the 1st type of additives. IR analysis of modified samples showed that when applying the additive complex the hydration and crystallization processes become more intensive, especially in the presence of SCNT with Portland cement and microsilica, and when metakaolin with SCNT is introduced – the worst conditions for binder hydration and crystallization are provided. The microstructure analysis of reference and modified samples allowed revealing the availability of new formations in the sample structure and changes in the morphology and sizes of crystalline hydrates
