In the quest to reduce energy consumption in construction, a team of researchers led by Aleksey D. Zhukov from the National Research Moscow State University of Civil Engineering has made a significant breakthrough. Their study, published in the journal ‘Нанотехнологии в строительстве’ (Nanotechnologies in Construction), introduces an innovative low-energy binding agent for stone wool-based products, promising to revolutionize the insulation industry.
The primary goal of Zhukov’s research was to develop an eco-friendly, energy-efficient binder for mineral wool products. Traditional binders require high temperatures, typically between 240–320 °C, for curing, which is energy-intensive and costly. Zhukov and his team aimed to reduce this energy demand by exploring the potential of modified epoxy compounds as binders.
“We wanted to create a binder that not only reduces energy consumption but also maintains the operational durability of mineral wool products,” Zhukov explained. The team’s investigation led them to an optimal composition of a modified epoxy binder, comprising 6% modifier (a latent component) and 3% plasticizer. This innovative binder can be cured at a significantly lower temperature of 150–154 °C, cutting energy costs for heating by 50% and lowering overall heat use by 20–30%.
The implications for the energy sector are substantial. Mineral fiber products, including basalt, glass, and stone wool, are widely used for thermal and sound insulation. Their application reduces energy consumption for cooling and heating in buildings. With Zhukov’s modified epoxy binder, the energy efficiency of these products is further enhanced, making them even more attractive for commercial and residential construction.
The research also introduced a digital method to study the technology behind the modified epoxy binder. This approach not only streamlined the development process but also provided valuable insights into the formulation and technological parameters of the binder.
In terms of performance, the modified epoxy binder demonstrated impressive results. After curing, the adhesion strength to mineral surfaces reached 58.4 MPa, the tensile strength of the binder was 77.4 MPa, and the adhesion strength after climatic testing was 29.1 MPa. These properties are comparable to those of products manufactured with traditional binders, ensuring that the operational durability of mineral wool products remains uncompromised.
The commercial impacts of this research are far-reaching. Construction companies can now produce mineral wool products with a significantly reduced carbon footprint, appealing to environmentally conscious consumers and meeting stringent regulatory standards. The energy savings translate to cost savings, making these products more competitive in the market.
As the construction industry continues to evolve, the demand for sustainable and energy-efficient materials will only grow. Zhukov’s research sets a precedent for future developments in the field, encouraging further innovation in low-energy binding agents and digital modeling techniques. The study not only addresses current energy consumption challenges but also paves the way for a more sustainable future in construction.
In the words of Zhukov, “This research is a stepping stone towards a more energy-efficient and sustainable construction industry. We hope our findings will inspire further innovation and collaboration in this critical area.” With the publication of this groundbreaking study in ‘Нанотехнологии в строительстве’, the construction industry is one step closer to achieving its sustainability goals.
