In the heart of Moscow, researchers at the D.I. Mendeleyev University of Chemical Technology of Russia are pioneering a novel approach to composite materials that could revolutionize the construction and energy sectors. Led by Valery P. Meshalkin, a team of scientists has been exploring the potential of framed composites based on liquid glass, a technology that promises to enhance the durability and sustainability of building materials.
The research, published in the journal ‘Нанотехнологии в строительстве’ (Nanotechnologies in Construction), delves into the experimental and theoretical study of composite materials based on soluble glass. The team’s innovative method involves a two-stage process: first, gluing grains of large filler to each other to form a porous frame, and second, filling the voids of the hardened frame with a solution component. This technique, known as frame technology, is combined with roller molding to compact the frame and fill its voids with a matrix.
“Our goal was to conduct a comprehensive study of the manufacturing technology, physical and mechanical properties, and chemical and biological stability of composites based on liquid glass,” Meshalkin explained. The team used sodium liquid glass as the primary material, sodium fluorosilicate as the hardener, and various powders based on mineral and organic materials as fillers. Furyl alcohol was employed as a polymer additive to enhance the properties of the composites.
The results of the study are promising. The optimization of the compositions of frames and matrices for framed concretes revealed that the best strength characteristics were achieved with filler mixtures of quartz sand, pyrite cinders, and diatomite. The greatest strength of the framework was obtained by including granules of specific sizes in precise proportions.
The chemical and biological resistance of the composites was also a focus of the research. The team found that composites containing modifying additives exhibited higher resistance rates. This is particularly significant for the energy sector, where materials must withstand harsh chemical environments and biological degradation.
The implications of this research are far-reaching. The development of scientifically based solutions for improving the compositions of frame and matrix mixtures could lead to the creation of more durable and sustainable building materials. This, in turn, could have a significant impact on the construction and energy sectors, where the demand for high-performance materials is constantly growing.
As Meshalkin noted, “The scientific and technological foundations for managing the structure and properties of liquid glass framed composites of vibration-free roller molding have been developed.” This breakthrough could pave the way for future advancements in the field, offering new possibilities for the design and construction of energy-efficient and environmentally friendly structures.
In conclusion, the research conducted by Meshalkin and his team at the D.I. Mendeleyev University of Chemical Technology of Russia represents a significant step forward in the development of composite materials. The findings published in ‘Нанотехнологии в строительстве’ (Nanotechnologies in Construction) offer valuable insights into the potential of framed composites based on liquid glass, highlighting their strength, durability, and resistance to chemical and biological degradation. This research not only advances our understanding of composite materials but also opens up new avenues for innovation in the construction and energy sectors.
