In the technology of a number of ceramic and refractory materials, prepared on the basis of highly concen
trated ceramic binder suspensions (HCBS), elements of effective nanotechnology were realized even before
the present “nanoboom.” The concept has been formulated of an advance in materials technology based on
HCBS both in traditional fields of their application, and in the field of structural materials science, within
which for industrial introduction of existing developments it is necessary to create contemporary equipment
formulation for production processes.
Keywords: highly concentrated ceramic binder suspensions (HCBS), ceramic concrete, nanoparticles, colloi-
dal component, strengthening by chemical activation of contact bonds (UKhaKS-mechanism) process, grind-
ing, building materials, binders.
Most recently there has been an increase in the field of
research and development of technology based on prepara-
tion and application of highly concentrated ceramic binder
suspensions (HCBS). For example, this is indicated not only
by the significant number of papers at conferences of refrac-
tory workers and metallurgists (2006 – 2010) devoted to ce
ramics and refractories in the aspect of nanotechnology
[1 – 3], but also in numerous publications by various authors
in periodicals. For example, just in the journal Ogneupory in
2010 about twenty articles were published, within which the
terms HCBS and ceramic concretes are provided or they are
in the headings of articles or texts. Judging from the content
of some of them [4 – 8], recently there has been marked ex
pansion of the scale of interest in this subject. A significant
amount of research in this field is carried out in the V. G.
Shukhov BGTU by our scientists and followers; this is con
firmed by an increase in the number dissertation works.
There has been marked expansion in the field of materials
and technology studied, i.e., from ceramics and refractories
to building materials for broad application [9 – 17]. At the
end of 2005 for the first time in the RF a teaching and scien
tific center “nanosystems in building materials science” was
created in the V. G. Shukhov BGTU, which to a considerable
extent specializes in development and implementation of the
technology in question applied to the needs of the building
industry [5, 10 – 13, 16, 17 – 20].
HCBS AS AN EXAMPLE OF EFFECTIVE
IMPLEMENTATION OF NANOTECHNOLOGY
FOR THE DECADE BEFORE THE PRESENT
A significant increase in the interest of researchers and
specialists in the sphere of HCBS technology is connected in
our view with occurrence of the present “nanoboom” em
bracing scientific and technical society at the beginning of
this century. Many specialists of inorganic material science
consider that the technology of materials prepared on the ba
sis of HCBS, and elements of nanotechnology were success
fully implemented in the 1960 – 1980s, i.e., when the dimen
sions of ultrafine particles were expressed in angstroms, and
there was no mention of nanotechnology [21 – 22].
Even in the second half of the 1960s, in our work for
quartz ceramics technology the effect of achieving high me
chanical strength of castings (binder properties of suspen
sions) was explained by “work hardening” during wet grind
ing of silicic acid and fine particles of “silica sol,” i.e., parti
cles of colloidal dispersion (the level of contemporary
nanoparticles). Whereas in all of the known previous studies,
concerning preparation of quartz ceramics by slip casting, in
