Refractory, comprising a porous filler in the form of expanded rocks such as hydrobiotite and perlite, was developed by employing ceramic or ceramic-chemical binders based on clay raw materials characterized by varying refractoriness and plasticity. The structural transformations of the materials at elevated temperatures were analyzed using x-ray diffraction and electron microprobe analysis. The density of samples based on hydrobiotite and a clay-phosphate binder increased by 30 – 35% compared to samples based on a ceramic binder. In samples containing perlite filler, the introduction of a phosphate binder had no significant effect on apparent density. The incorporation of a pre-synthesized clay-phosphate binder based on red-firing clay into the initial perlite mixture resulted in a two-fold increase in strength without increasing density or thermal conductivity of the material. The testing of strength characteristics in perlite–ceramic samples with different phosphate binders over the temperature range of 300 – 950°C revealed strength stability up to 800°C, which indirectly reflects the structural transformation and operational temperature range of the material. Thermal insulation materials with enhanced thermal and mechanical properties were fabricated by semi-dry pressing using the following compositions: expanded hydrobiotite – secondary Samarkand kaolin and expanded perlite – secondary Samarkand kaolin – clay-phosphate binder based on red-firing clay.

An effective technology for the production of construction materials using local resources, including non-standard raw materials and industrial byproducts, has been developed. This development is significant in both environmental and economic terms. The experimental phase focused on the application of semi-dry pressing and hyperpressing techniques to improve the operational properties of concrete mixtures. During the pressing process, especially under hyperpressing conditions (pressure greater than 40 MPa), intense interparticle interactions are expected to form macrostructures that contribute to a more robust cement stone structure. The involvement of van der Waals forces and valence bonds between filler particles and hydrated clinker minerals, as well as molecular interactions, is considered to be the central mechanism promoting the increase in strength and stability of the material. An important aspect is the use of low plasticity clays and overburden rocks, as well as industrial waste, which allows a significant reduction in production costs and improves environmental sustainability. Hyperpressing technology has been shown to shorten production cycles, reduce energy consumption per unit of output, and improve economic efficiency.
