Sukhanevych M. Scientific bases of obtaining hydroisolating solutions based on cement composites modified with carbon nano-additives

Dissertation work is devoted to the development of scientific foundations for production of waterproofing mortars with different mechanisms of action (penetration and superficial) on the basis of Portland cement, of frame aluminosilicates (zeolites) and layered (bentonite) buildings that modified by complex additives based on carbon nanomaterials (untreated carbon nanotubes and expanded graphite) and plasticizers of various composition. The proposed principles of composite construction waterproofing mortars, surface and penetrating action on the basis of nanomodified concrete compositions, which incorporate directional control processing of structure formation in all hierarchical levels of structure: nano-, micro - and meso- levels. The physical and chemical regularities of the processes of hydration and hardening of nanomodified cement systems, which consist in the acceleration of crystallization processes in the presence of carbon nano-additives, which act as backings for the syntesed of hydrated new formation of elongated forms and occurs accelerated epitaxial knots, allowing to obtain a dense waterproof structure of artificial stone. In the thesis we have developed an integrated approach to the management of properties of cement mortars at all hierarchical levels of the structure receiving durable waterproof coatings with improved operational characteristics, including increased water resistance, weather resistance and corrosion resistance. Implemented industrial introduction and assessment of the technical and economic efficiency of nanomodified waterproofing mortars to improve the durability of concrete structures.
