Structure formation of construction materials modified with natural and man-made nanoadditives

Abstract

The article focuses on the study of influence of natural and man-made nanoformations (chrysotile fibers, carbon black, and graphite) on the formation of the structure of the material based on a hydraulic binder. The data on the positive effect of the optimal amount of modifying dispersions on the physical and technical properties of the samples were obtained. On average, the increase in compressive and bending strength, when using the considered additives, is from 10 to 40%. The results of the study of the microstructure and IR spectra of the check and modified compositions show that adding natural and man-made nanosystems provides optimal conditions for the formation of strong, dense new formations in the cement matrix. In general, the data obtained prove the effectiveness of their use in comparison with synthesized carbon nanosystems.
