Strength properties of high-strength concrete on the basis of a mixture of high-calcium ash and cement crushed to a specific surface of 600 m2 / kg in the presence of a superplasticizer were investigated. It was established that at the initial stages of hardening of the binder, its strength strongly depends on the dosage of fly ash and it depends little on the water/binder ratio. After 28 days of hardening, the strength of concrete, depends more on the water-binder ratio, rather than on the ash content of the cement-ash binder. There was concluded that minerals of fly ash affect on strength of the cement-ash binder in later periods, and at the initial stages, its hardening is provided by hydration of the cement clinker. It was established that in high-strength concretes was no decrease in strength in later periods when using finely grinding ash containing a significant amount of free CaO.

Piezoceramics phases of (1-х)PbTiO3-xPbZrO3 is the basis of most high-performance piezoelectric materials. Electrophysical and mechanical properties of these materials can be varied over a wide range by varying the composition and by processing methods: the methods and modes of sintering conditions polarization. Topical to study the influence on the properties of PZT materials processing methods at the stages of manufacturing piezoelectric samples. In the role model of the object has been selected multicomponent system PbTiO3-PbZrO3-PbNb2/3Zn1/3O3-PbW1/2Mg1/2O3-PbSb2/3Mn1/3O3. Samples of piezoelectric elements for the study were obtained in two ways: in the first case, the sintering samples was carried out by the usual ceramic technology, and in the second by hot pressing. The grain structure was formed in both cases in the presence of the glass phase, the quantity of which decreases with increasing temperature, while in the first case, an increase in the velocity of the secondary recrystallization, and in the second of its suppression. It was found that regardless of the technology of the samples εT33/ε0, d33 and VЕ1 at high temperatures, due to the increase of grain and coercive field, which complicates the process of polarization. Maximum values εT33/ε0, d33 and VЕ1 samples prepared by hot pressing at 10 - 15% higher than if received by conventional ceramic technology.

Numerical-analytical solution of the problem of multicomponent mixture fractionation under action an electric field is constructed. This problem is known as the problem of zonal electrophoresis which extensively used in chemistry, medicine, and biology. Problem is reduced to study of the Cauchy problem for systems of hyperbolic type quasilinear equations in partial derivatives of first order. The proposed method is based on a generalized hodograph method, which allows obtaining an analytical solution of the problem in implicit form. Explicit form of the solution is recovered using the transformation of the Cauchy problem for system of quasilinear hyperbolic equations to the Cauchy problem for a system of ordinary differential equations that are solved numerically.
