Resistance of Silicate Materials to Hot Water. Results of Researches of Silicate Products Manufacturers
Some normative documents limit the use of silicate brick for masonry of external walls of basements as well as for walls of premises with wet conditions of operation. Silicate materials
have been long and successfully used for construction of foundations, cellars, and WC-and-bathroom units, first of all in low-rise housing construction in Germany, the Netherlands,
Swiss, and Austria. The aim of the study conducted is a proof of the sufficient durability of silicate materials in hot water and their ability to maintain the most important qualities
(strength, exterior view) for a long time. It is established that in the course of boiling, the strength of silicate brick increases insignificantly. Under the long-time hot water impact,
strength parameters of silicate brick demonstrate a more complicated dependence.
Keywords: silicate products, compression strength, durability of silicate brick, resistance coefficient.

Pigments and Volumetric Coloring
Volumetric methods for coloring of the molding mix with iron oxide pigments, when manufacturing the silicate brick, have been studied. Issues of the coloring of the mix with slaked
lime and quicklime are considered. The time of appearance of the mix color and its intensity was fixed at the stage of coloring. It is established that good coloring of light tones with the
pigment is reached at introducing the pigment before the lime slaking. Introduction of the pigment in the slaked mix demands to increase the mixing intensity. Adhesion of the slaked
lime impedes the distribution of the pigment in the mix that leads to the loss of products color. Quicklime as an abrasive material contributes to the distribution of the pigment in the
volume. When coloring the slaked mix with light pigments, it is necessary to increase the mixing intensity. The intensive mixing leads to the strength growth. The introduction of pig-
ments of bright tones with great coloring ability with the purpose to reduce the losses at color transition is recommended in the slaked lime. Physical-mechanical characteristics of
pressed samples as a result of introducing the pigment in the slaked lime and quicklime were studied. It is established that the increase in the quantity of the pigment (over 2%) in the
slaked lime leads to reducing the raw and autoclaved strength of pressed products.
Keywords: silicate brick, pigments, slaked silicate mass, unslaked silicate mass.

The results of studies on the effect of the manganese containing wastes on the volumetric colouring of wall ceramics depending on the method of product manufacturing. The palette of
resulting colour codes is defined (by the additive RGB color system) for ceramic samples from clay raw materials at various additive contents of manganese ore mining wastes in the
mixture composition. A substantial coloring enhancement of ceramic products with matrix structure occurres due to the introduction of powdering additive of wastes containing MnO2 in
the amount of 5–10 wt. %, compared with the samples produced by plastic moulding. It is established that the formation of a ceramic matrix composite provides a concentration of the
coloring component in the matrix and prevents its negative influence on the sintering of clay granules during firing.
Keywords: decorative wall materials, manganese containing wastes, compression moulding, ceramic matrix composites.

Evolution of the Theory of Concrete Strength. From Simple to Complex
A model of the structure of cement composites based on the principles of the fractal geometry according to which the complex systems of nature consist of parts (fractals), which at
each scale level is like the whole, is proposed. It is shown that the classical theory of strength does not reflect the real picture of the resistance of fractal structures to destruction. It is
experimentally and theoretically proved that the destruction of cement composites is a multi-level, multi-stage process; under the action of compressive loads, the concrete structure
can be destroyed both by cleavage and by cutting; a fractal model more exactly describes the relation between compression and tension, scale effect, dependence of compression
strength on the friction coefficient. Deformation diagrams obtained with the use of the software complex “Welle Geotechnik” confirm the discrete-continuous character of the destruction
of cement composites under compression.
Keywords: concretes, fractal, scale level, composite, destruction, quantum nature.

New Sulfur-Containing Materials for Road Construction
The relevance of the work is determined both by the problem of efficient utilization of increasing sulfur industrial discharges and the possibility of using local weak stone materials which
are not widely used. It is established that the impregnation of sulfur melts into the pores of crushed stone facilitates the formation of a durable gradient layer with changed properties
that resulting in increasing the hardness of grain surfaces and manifestation of hydrophobicity and that in its turn affect the change in operational-technical properties of crushed stone.
This, the index of crushability of processed crushed stone reaches the value of 1200, and the water saturation index reduces. The produced material can be used in the bases of road
pavement structures as well as in compositions of hot asphalt concrete mixes. Thus, asphalt concretes with processed crushed stone regarding the values of compressive strength and
resistance to fatigue exceed the minimal requirements of GOST 9128–2013 set for B type by 1.5–2 times on the average.
Keywords: sulfur, crushed stone, impregnation, asphalt concrete, auto road.
