Аннотация:The new theory of strength of composite soil cement-based materials with carbon nanostructures (CNT) has been developed from new positions of the structural-energy concept. Changes of strength of composite soil cement-based materials with CNT are the product of the binding energy of the structure of the film of new formations and the degree of disorder in the system, occurring with changes in the content of its individual components. Changes of strength of composite soil cement-based materials with CNT are the product of the binding energy of the structure of the film of new formations and the degree of disorder in the system, occurring with changes in the content of its individual components. The compositions of composite materials, which can serve as tires and coatings technogenic, geochemical barriers, screens with record performance properties that protect against electromagnetic radiation, from man-made pollution and can be used in road construction and civil engineering.
