Influence of innovative technologies on the physical and mechanical properties of building materials in the construction industry
Abstract
A multifunctional additive based on a gel-like dispersion of taunitic carbon nanomaterial (CNM) is considered. The influence of its quantitative composition on the physical and mechanical properties of fine-grained concrete is studied. The results of a study of the frost resistance of fine-grained concrete enriched with a gel-like dispersion of CNM "Taunit" are presented.The main hypotheses describing the formation of the porous structure of concrete under the action of alternate freezing and thawing are considered, and the influence features of the structure of nanomodified concrete on its frost resistance and density. Nano-modified fine-grained concrete was tested by scanning microscopy, which shows that the process of forming changes in its structure occurs not only as a result of reinforcement, but also as a result of growth crystalline hydrates, the centers of which are particles of CNM "Taunit".
