This article presents the research of dependencies
with a filler in the form of fly ash, the mixture temperature and other
influencing the kinetic characteristics of composite foaming based on
mixture of thermosetting resin (phenol-formaldehyde resins of different
brands), fly ash and special modifiers.
The article describes the performance properties
of highly filled polymer-fly ash mineral composite based on polyvinyl
which affect the durability of construction outdoor products. The
article presents the results of studies to
determine the coefficients of thermal expansion of polymer-based
mineral, filled with PVC TPP fly ash, to accelerate climatic tests,
stability to UV radiation.

This work is devoted to the research of the
strength and elastic properties of the laminated fiberglass composite.
Experiments were performed on tension and compression of specimens with
different orientation of the reinforcement in relation to the loading
direction. The predictions of three different failure criteria (Hill
Tsai-Wu criterion, Zakharov criterion) were compared to experimental

The article contains the results of tensile testing of different types
of FRP samples, the character of their destruction, dependence of the
and elasticity module on the bars diameter. The results are compared
calculated values of tensile strength of steel reinforcement. Based on
these results we arrived at conclusions about the comparability
of the design values tensile strength of FRP with high-strength steel

Calcium aluminates have a
decisive influence on the hydraulic activity of cement, in this regard,
detailed study of them is an urgent task. The aim of this study is to
the phase composition and detailed analysis of the structural-phase
monoaluminate calcium by X-ray analysis. To research
calcium powder diffractometer DRON4-07 was used, it has been modified
digital signal processing. Shooting was performed on the copper
scheme Bragg – Brentano 0,020 increments and the exposure
time at 1 sec, the
angular range 6–82°.
Calcium sulfoaluminate (CSA) is a comparatively
cementitious material that is mainly established in China where it is
in a large scale. CSA cement is not covered by European standards.
provides different beneficial properties such as rapid hardening and
strength development. Furthermore, the usage of CSA cement can save
during production process in comparison to established cementitious
The main purpose of this research is to create the
new reference method to determine the freeze-thaw resistance of
is characterized by small labor inputs, high efficiency and a wide
application. The offered method is based on the measurement of long
a nondestructive method. During this research, the theoretical analysis
concrete specimen dependence on freeze-thaw resistance and energy,
emitted by a specimen during destruction, has been carried out.

Wood is an environmentally friendly and lightweight
building material that is sensible to the destrustion of various
agents at non-observance of proper temperature and humidity regime.
Wood-destroying white-rot and brown-rot fungi and micromycetes (mold)
leading position among biodestructors. This organisms use wood as the
base changing it’s chemical composition and correspondingly
it is mechanical
