“…At present, materials science increasingly frequently considers the main properties of substances, phenomena and processes partaking in the formation of a construction composite at the nanoscale. Due to their unique mechanical, thermal and optical properties, carbon nanomaterials are of great interest not only as a scientific research object but also as an object of technology providing control over structure formation of a composition, creating new properties and the quality level [1][2][3]. By introducing small concentrations of carbon materials into the cement matrix or their synthesis in the process of composite manufacturing, it becomes possible to exercise the directed control over formation of products' performance properties [4][5][6][7][8][9].…”

“…It is important to note that in both the development of new modifying materials on the base of primary carbon materials and the application of existing additives, their comprehensive study is a must [1][2][3]. However, regardless a dispersive system in consideration, the researchers come across the common issue related to ensuring effective dispersion and even volumetric distribution of primary carbon materials in both the carrier and composite matrix due to spontaneous aggregation specific to carbon nanomaterials [3]. There is a way of incorporating nanomaterials into a cementitious composite in which the nanomaterials such as carbon nanofiber (CNF) and graphene oxide are coated on the fiber instead of direct addition into the dry mixture [18,19].…”

Properties of Bitumen Composition Modified by Petroleum Resins

“…One of the ways to improve the quality and durability of bitumen coatings is to modify bitumens with mineral and synthetic polymeric materials. For example, primary carbon nanomaterials increase the physical and mechanical properties of petroleum bitumen and construction materials based on it, provided they are evenly distributed in bitumen [1]. Thermoplastic linear polymers, general purpose rubbers and thermoplastic elastomers are mainly used in bitumen-polymer compositions [2,3].…”
