HOMOGENIZATION OF NANO-MODIFIED CEMENT SYSTEMS AND SELECTION OF PARAMETERS OF THEIR TREATMENTIN VORTEX LAYER UNITS
Overview of application of nanotechnologies in production of construction materials is provided in the article. Successful cases of application of nano-materials and nano-particles in the construction industry are described, including molecular indicators informing about the stress-deformable state of bearing structures, coatings accumulating solar energy, and self-cleaning paints and varnishes. One of the core difficulties of introduction and uniform distribution of nano-particles is identified in the course of consideration of nano-modification and nano-disperse reinforcement of the cement stone. The problem is caused by the miniature dimensions of particles of modifiers and their small amounts. Employment of vortex layer devices, namely, the Process Activation Device, is proposed by the authors. These devices can ensure an appropriate extent of hashing. Thus, the two problems are eliminated by one solution: one is the uniform distribution of nano-disperse additives over the modified cement system and the other one is activation of initial input products. In the article, certain optimal parameters of the process of mixing a small mass of nano-disperse modifiers with building mixes (cement systems) are provided.
