In the article there brought the researches of processes of
crystallization of hydrates, of the formation of structure of cement
materials on micro- and macrolevels, of the character of distribution
of microparticles and units in the compounded cement matrix, their
form, a relative positioning and influence. The modelling of processes,
and also the analysis of own experimental data is made.

The article is devoted to the technique of thermophysical tests of the
aerocrete blocks developed by the authors. The urgency of the research
is provided by the fact that application of such blocks without filling
of the vertical joints are not considered in the Russian normative
documents because of absence of the data about thermal resistance of

Gorshkov, P.P. Rymkevich
In the present paper the estimation technique of the operational
service life for the two-layer wall designs is described.
simultaneous laboratory and natural tests were conducted within 4,5
P.N. Nedviga, V.А.
During the work the technique of tests of the steel cold-worked
thin-walled beams with absence or presence of the longitudinal
punchings has been offered, and corresponding dependences are received.
The beams were tested for the durability, and dependences of the
durability on the constructive and technological parameters were
In the article the Petersburg organization's experience in the
repairs of Palace quay site is described. The sparing
which allow to conduct works in historic centre are considered. The
basic technology is use of drilled-and-injection piles.
The article is devoted to the use of the steel-fibro-concrete in
manufacturing of piles. Also some extracts from history of the
foundation engineering and from the classification of piles are quoted.
The article is devoted to the important subject of the pipe covering.
The use use of the monolitic foam concrete is comparatively new method
in Russia. In the article there are the exmples of calculation of the
thickness of the layer of the foam concrete in the case of different
types of laying.
Air exchange is one of the most important parameteres of the
quarters for the design of climatic systems. In the article there is an
analysis of the physical meaning of this characteristic and its
influence on the health of people.
It is the continuation of the article of this
7, 2009 of our magazine. It contains the analysis of stress and
deflection distribution on the field of a shell.
A new article from the series concerned to the modelling and
The author study the influence of organizational and
technological parameters on the level of the reliability of
design solutions. The general strategy of the design solutions is
