In summary form, some trends in the production and application of foamed silicate materials obtained from recycled waste materials are presented. The existing possibilities for the use of different fractions of foam glass granules for the preparation of various products (lightweight concrete, colored decorative panels, etc.) are considered. Experimental samples are prepared in which the average value of the thermal conductivity coefficient =0.24±0.13 W/m. K was established. The main technological factors determining the operational characteristics of the material and the existing potential prospects for their optimization are analyzed.

A conceptual design of a technological line for the production on the one hand of a continuous flat strip and block and on the other hand granules and pieces of foam glass, including a ware house for raw materials, a workshop for preparation of materials, workshops for foamed granules and a continuous flat strip of foam glass, workshop for composite elements semi O, P and slabs, repair section and warehouse for finished products is presented The necessary equipment and materials, building the technological line and functioning of the plant as a whole, are presented.

Experimental ceramic samples were obtained in which the presence of CaMgSi2O6 (predominant phase), MgCr2O4, CaAl2Si2O8 and quartz was detected by X-ray diffraction analysis. During the microscopic examination of the prepared sections, two mineral phases were established: main – clinopyroxene and secondary – green spinel. The presence of prismatic-granular and skeletal structure was found. In the formed dominant diopside phase the presence of numerous inclusions of magnesium-chromium spinel with green color (sizes up to 0,05 mm) was observed evenly distributed in the sections determining the characteristic green color of the samples.

Compression was carried out of modified copper powder workpieces at a pre-determined value of the pressure. High temperature sintering of the workpieces in a neutral medium at a temperature of 1,000°C was performed. A high density metal-ceramic composite material was obtained. Its structure and physico-chemical parameters were determined. Lead-free prototypes were created, corresponding to the weight and dimensions of the reference standard lead passive elements for high energy impact.
