Since the construction industry is very energy intensive, there is a question of drastic reduction of energy consumption in all types of buildings.
With the increase in the quantity of the C-3 additive from 0.8[%] to 1.0% of the cement mass, there is a noticeable reduction in the strength of the sprayed concrete.
The reduction in the strength of the shotcrete is due to the noticeable air attraction during the preparation of the concrete mixture.
The data obtained indicate that in three-layer construction structures it is possible to use insulators from «Polystyrene plates» with a density of 10 [kg/m3] as well as shotcrete with small filling and cement of a certain brand.

The assessment was based on monitoring data concerning the certain priority parameters obtained from the selected representative measuring points.

The recommendations on the possibility of application of data obtained during the experiment for the development of mathematical models of sanitary and ecological state of the Neva bay and the eastern part of the Gulf of Finland were formulated: · for correlation and regression analysis of the obtained data · for formulation of empirical statistical model of ecological condition · for verification of the forecast models of distribution of pollutants in the aquatic environment References [1] Karatygin P., Chronicle of Petersburg floods 1703-1879, Publiching House of Suvorin, St.

In all studies the effects of fatigue cycles produced a reduction of the static strength as expected.
Specimen Preparation One critical limit state of civil structures are fatigue and long term behaviour and previous reviews of existing data from mechanical and aerospace applications are often used to determine the applicability to civil constructions.
However these data are sometimes incomplete and more research is needed, especially for the long-term mechanical behaviour of composite materials.
Because frequencies of fatigue load under 4-5 Hz have demonstrated to produce limited effects in GFRP composites [3], only the data for which the frequency of fatigue was greater than 7.5 Hz was used in this experimental study.
From the experimental data it was seen that fatigue load up to 1.0 kN did not produce important degradation.

Correlation of workability test results and rheological test results of Fresh concrete Among investigations on correlation of various workability data and rheological data [1-11], the workability tests are concentrated within a narrow scope including slump, slump flow, L-flow (or L-box test), and V-funnel, while the rheological test data are only yield stress and plastic viscosity based on the Bingham fluid model.
Compared with experimental data of slump, there are less data reported on the relationship between tests of slump flow, V-funnel, or L-box, and rheological properties.
Based on the relationships established between workability data and rheological data, it was concluded that the V-funnel flow time test correlate well to plastic viscosity and yield stress of highly flowable underwater concrete, with R 2 values of 0.81 and 0.83, respectively.
A decrease in flow time resulting from a reduction in cohesiveness could then lead to greater loss in washout.
Such researches seem full of both experimental data and correlation equations along with high or low correlation factors, which really means that a great deal of experimental and calculation work have been done.

Coarse and fine grains samples were cold rolled up to 90% thickness reduction and annealed at 880°C with soaking time of the 24 s.
The cold rolling of the coarse grained and fine grained samples were performed in the laboratory with reduction from 6 mm to 0.60 mm (90 % reduction in thickness).
The data processing was carried out in the OIM analysis software (EDAX).
Therefore, the stored energy increases with the reduction of the grain size before deformation.

Data base Production (quality control) yes no Adjustment of customer requrements Fig. 2.
The main process technological parameters influencing the designed process are the number of revolutions of wire twisting, reduction in the first die and reduction in the second die.
Thus wire strengthening after combined deformational processing was about 10 % higher as compared with drawing with the same total reduction.
At minimum reduction in the second die with the increase in rotation velocity of the roller system ultimate tensile strength decreases up to wire breakage.
The biggest plasticity increase is characteristic for the drawing sequence with the biggest reduction in the second die.

The XRD data reveals that the intensity of the Fe2O3 has decreased when the concentration of the polymer is increased in the composite.
The complex impedance data for this has been analyzed in different formalisms such as permittivity (e) and electric modulus (M).

This result indicates that the displacement of ions is thermally activated; these results are found to be comparable with the temperature dependence of the conductivity data.
For the given temperature and frequency, the real part M' and the imaginary part, M" of complex modulus were extracted from impedance data.

Fastness properties of the samples, such as light fastness, washing fastness and rubbing fastness, were examined and the fastness data of tea and Apocynum dyed samples are given in Table 3.
It is observed from wash fastness data that, all the tea and Apocynum dyed samples showed very good wash fastness rating of 5 and no staining on adjacent white fabrics (wool/silk and cotton) was examined.
The results showed a less 10% reduction rate.
