AP26101925 – Structural and thermal insulation concrete for 3D printing using waste plant materials

Objective of the project – The economic and social development of Kazakhstan focuses on creating seismic-resistant construction materials with low metal content, reduced costs, and labor requirements, enhancing thermal insulation properties, and reducing material consumption and building weight. Emphasis is placed on accelerating technological progress in construction through energy-efficient, thermal-insulating materials made from local raw materials. The use of secondary resources is key, alongside developing energy-saving technology and a new raw material mixture for producing lightweight structural wall blocks from agricultural residues and modified local binders with improved properties.

Relevance: The relevance of the project lies in the need to develop economically and energy-efficient construction materials for low-rise buildings in Kazakhstan using local plant-based raw materials and agricultural waste. The development of structural-thermal insulation concrete for 3D printing allows reducing the weight and material consumption of buildings, improving thermal insulation properties, utilizing secondary resources, and lowering production costs, while also enhancing durability and resistance to water, fire, and chemical impacts. This approach contributes to the development of eco-friendly technologies in the construction industry and the rational use of local raw materials.

The dissemination of research results in the publication of articles and the publication of monographs involves the dissemination of works among potential users of production workers, the business community, scientists and the general public. To scientifically substantiate and experimentally confirm the effectiveness of lightweight arbolite and mineral raw materials. Theoretically substantiate the compositions of lightweight arbolite, taking into account the criteria for evaluating raw materials.

6) other measurable results in accordance with the requirements of the tender documentation and the specifics of the project. Additionally, the section specifies:

1) scope and target consumers of each of the expected results;

The target consumers of scientific and technical research of the project are universities engaged in training students in the field of Production of building materials, undergraduates, PhD doctoral students and scientific and technical workers of research organizations, as well as business communities that can put into practice the production of lightweight arbolite for thermal insulation of buildings.

In the current year, the project will conduct a multifactorial study of structural-thermal insulation concrete made from rice husks using modern non-destructive testing equipment. The developed mixtures can be recommended for small-scale production of large-sized components using products derived from rice processing waste. The novelty of the work lies in the scientific and technological foundations for controlling the structure and properties of concretes formed by additive construction methods (3D printing).
