Nano-Modification of Concrete with Slurries Using Ultra-Jet Technology

Abstract:

The article discusses the problem of increasing the strength of concrete through the use of a suspension based on nanomodified additives with boehmite, graphene and carbon nanotubes. The lack of high performance and efficient dispersion methods limits the possibilities for nanomodification of building materials. Therefore, the research topic associated with assessing the possibility of developing means and methods for dispersing hydrocomposites containing nanoparticles is relevant. The suspensions were treated with ultra-jet treatment. Nano-containing suspensions were studied using a Microtrac Bluewave laser particle size analyzer. The analysis results were the average particle sizes in terms of quantitative and volumetric distributions, as well as the minimum recorded particle size in the samples. The results of compressive strength tests of a batch of concrete samples are presented. It is shown that the use of nanomodified additives leads to an increase in concrete strength.
