Abstract:

Over the last ten years, Ukraine has accumulated a considerable quantity of wastes from mining, metallurgical and chemical industries, which worsen the ecological situation in the country but they can be used to produce building materials such as bricks and building blocks.

Current technologies for manufacturing these products are energy-intensive. Therefore, the aim of this work is to study cold pressing of building materials with high specific loads. In this connection, the research was done in order to determine the main parameters needed for equipment design and blend composition for manufacturing building materials.

The studies were conducted mainly in two directions in walling building materials: strength and thermal conductivity. This is explained firstly by the fact that the material of a filler has low internal bonds, and secondly, by the presence of microcracks in the crushed material. It is determined influence of the following characteristics on strength formation: fraction of granule and the percentage of large and small granules.

The presence of microjointing in crushed material is an integral component to reduce heat conductivity.

Waste utilization to produce building materials reduces negative environmental load on regions with piles and tailings of primary production.

The studies carried out are the basis for the creation of the normative documentation for the equipment design and development of technological schemes of wallings production.
