AP26104663 – Development and research of compositions of thermal insulation materials based on the mineral resources of Kazakhstan – limestone-shell rock and waste from its extraction
Objective of the project – The purpose of the scientific project is to develop a scientifically based technology for obtaining compositions of thermal insulation materials based on fine fillers with improved thermal insulation and performance characteristics.
Relevance: In the context of implementing the strategic development priorities of the Republic of Kazakhstan, the introduction of resource-saving technologies in construction materials science is of particular importance. Despite its significant raw material potential, the country still lags behind economically developed nations in terms of rational use of mineral resources and the depth of industrial waste processing, which necessitates the search for new effective solutions.
One of the promising directions is the development of next-generation thermal insulation materials. In global practice, thermal insulation mixtures based on porous fillers with high performance characteristics are widely used. However, both domestic and international scientific literature insufficiently address the influence of modifying additives and porous components on the physicochemical processes of structure formation and the resulting properties of such materials. This significantly limits the advancement of their production technologies and application.
The use of local natural resources, particularly shell limestone, is of special relevance, as its reserves in Kazakhstan are substantial and widely distributed. At the same time, the potential of this material, including its mining waste, remains largely untapped in the production of modern thermal insulation coatings, especially those based on polymer binders.
In this regard, the development of effective compositions of thin-layer thermal insulation materials using finely dispersed shell limestone and its waste represents a scientifically and practically significant area of research. Such studies are aimed at forming an optimal coating structure, improving thermal insulation properties, and expanding the possibilities for the integrated use of local raw materials, which aligns with the goals of sustainable development and increasing energy efficiency in the construction industry of Kazakhstan.

Expected and achieved results: - technologies for the production of thermal insulation mixtures based on finely dispersed mineral fillers with improved performance properties;
- regulatory documents for the production of thermal insulation mixtures and recommendations for their use;
- the possibilities of organizing the production of thermal insulation building mixes based on mineral raw materials with enhanced thermophysical properties.
During the implementation of the project, the following tasks are addressed: the establishment of a new enterprise for the production of various types of thermal insulation coatings; an increase in gross regional product; import substitution and growth of budget revenues; meeting the demand of the population and the construction market for high-quality products; development of Kazakhstan’s industry and creation of new jobs.
In the production of coatings based on polymer binders, compliance with chemical standards is ensured, and the production process is certified as safe for the environment and human health. The use of coral stone and its waste reduces the cost of materials, decreases raw material consumption, and enables energy savings.
The cost of 1 m³ of coating based on polymer dispersion is approximately 137,332 tenge, while that of the dry mix is 110,400 tenge. With an annual plant capacity of 100 thousand m³, the expected economic effect will amount to 11.97 billion tenge for polymer-based coatings and 8.76 billion tenge for dry mixtures.
For the first time, the project develops compositions of thermal insulation coatings based on finely dispersed mineral fillers, determines their technological regimes, and, based on the study of the influence of fillers on structure and phase formation, establishes optimal compositions and technological parameters.
