Solution Overview
Problem
Existing construction materials lack a combination of high compressive strength and thermal insulation properties, while also being resistant to biological factors, which are essential for durable and sustainable building structures.
Innovation Solution
A method involving the production of a microporous concrete mass using a mixture of powdered activator and finely ground waste glass, followed by heating and rapid cooling to form granulated glass, and a mass for shaped construction elements comprising perlite, a binding agent, and water, where perlite grains are coated with a moist binding agent and compressed to retain shape, creating elements with high precision and repeatability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional construction materials are used, then structural strength is achieved, but thermal insulation properties deteriorate
Solution Approach 1:
The patent utilizes perlite granulate as a porous insulation material incorporated into the concrete mass. The perlite grains maintain their spherical shape with internal porosity, creating air-filled voids that provide thermal insulation while the cementitious binding agent ensures structural strength. This resolves the contradiction by integrating both load-bearing and insulation functions in a single composite material system.
Solution Approach 2:
The invention creates a composite construction material combining cementitious binding agent (providing strength) with perlite granulate (providing thermal insulation). The composite structure allows the cement matrix to bear mechanical loads while the distributed perlite spheres create thermal barriers, simultaneously achieving both compressive strength and thermal insulation properties.
2Ease of manufacture
If conventional concrete production methods are used, then manufacturing simplicity is maintained, but precision and repeatability of construction elements deteriorate
Solution Approach 1:
The patent employs pre-prepared perlite granulate with controlled size distribution and spherical morphology before incorporation into the concrete mix. This preliminary preparation of the insulation material ensures consistent performance and dimensional stability, improving precision and repeatability while maintaining ease of manufacture through a straightforward mixing process.
Solution Approach 2:
The invention optimizes specific parameters including the spherical shape and size distribution of perlite granulate, the water-cement ratio, and the mixing procedure. These controlled parameter changes ensure high precision and repeatability of the produced construction elements while keeping the manufacturing process simple and scalable.
3Strength
If standard construction materials are used, then structural integrity is achieved, but resistance to biological factors deteriorates
Solution Approach 1:
The perlite granulate creates a porous structure with closed-cell morphology that prevents penetration by biological agents such as fungi, mildew, and rodents. The air-filled voids and hydrophobic nature of perlite provide inherent resistance to biological degradation while the cement matrix maintains structural integrity, resolving the contradiction between strength and biological resistance.

Implementation Method 1
placing in a mechanical mixer a granulate, in the form of perlite, soaking it in water, until the granulate is completely soaked
Implementation Method 2
mixing with a binding agent, with plaster with improved parameters, until a state where each loose granulate grain is covered with a layer of moist binding agent

AI summary
The invention solves the problem of the manner of obtainment of mass for production of shaped construction elements. The manner consists of the fact, that in the mechanical mixer a ceramic granulate is placed, preferably in the form of pearlite and is soaked, preferably with water until complete soaking of the granulate and is mixed with the binding agent until obtainment of the situation, where each loose grain (1) of the granulate is coated with a layer of moist binding agent, creating a coating (2) around the grain. Priorly prepared moulds are filled with the obtained mass. The mass for production of shaped construction elements consists of 15-25 % of bond weight, preferably in the form of pearlite, 35-45 % of binding agent weight, preferably in the form of plaster with improved resistance parameters and 35-45% of water weight.
