Vernadsky Institute of General and Inorganic Chemistry NAS of Ukraine, Kyiv, Ukraine 4Frantsevich Institute for Problems of Materials Science, NAS of Ukraine, Kyiv, Ukraine *gvsokol@rambler.ru Keywords: manganese dioxide,electrodeposition, dopant-ion, Lithium, phase composition, Rietveld refinement, porometry Abstract.
This shape of isotherm characterizes them as materials having also a slit porosity.
As shown by porometry and XRD, undopedsemiamorphous materials have hollandite/ramsdellite domains intergrowth with sizes of coherent scattering regions less than 20-50 Å.

It is significant for the anti-shear properties of anchor filled with different materials, like twisted steel, cement.
The experiment was double-shear test, two kinds of anchor with seamless and seam were adopted, there were three kinds of filled materials with hollow, grouted and reinforced.

This article deals with using recycled concrete in cement-based composite materials.
Introduction Increasing amount of construction waste, cost reduction of building materials and reduction of non-renewable resources consumption require more frequent use of recycled materials in construction [1].
Better sorting and good knowledge of the source material provide more efficient applications to new building materials.
Based on grain size and specific surface area results of FGRC and cement it can be assumed, that both materials were milled at a similar level.

Introduction
Titanium and its alloys are utilized in aero-engine and airframe manufacture because of their outstanding strength to density ratios relative to other materials.
In addition the susceptibility of titanium to work-harden during machining impair their machining ability, hence they are referred to as difficult-to-machine materials.
As for capabilities, especially fatigue resistance, titanium alloy is better than other materials.
There have been several attempts to improve the machining ability of titanium alloys when machining dry and conventional coolant supply using advanced and conventional cutting tool materials.

The advantages of composite materials, on the one hand, can enhance the protection of iron oxide and reduce the loss of iron, on the other hand, can give full play to the synergistic effect between different materials.
In the selection of carrier materials, besides the stability of materials and the compatibility with iron, the cost factor is also very important.
Due to these materials are generally charged negatively and have large specific surface area, iron ions are easy to accumulate on the surface of clay materials or enter their internal space through ion exchange.
