Ceramics-Silikáty

As the construction industry continuously develops, people increasingly require better building materials. Traditional concrete materials struggle to meet these demands due to their high brittleness, low compressive strength, and weak corrosion resistance. To solve these problems, this study optimises concrete’s mechanical properties by introducing prepared nano-SiO₂ and glass fibres. This approach aims to improve the compressive strength, flexural strength, and corrosion resistance of concrete. After analysing the various properties of the prepared nano-SiO₂ glass fibre concrete, it was found that the permeability coefficient of the concrete decreased from 5×10^-12 m/s to 1×10^-12 m/s, and the water absorption rate of the concrete decreased to 2.2%. In addition, in testing the mechanical performance of concrete, the compressive strength of the nano-SiO₂ glass fibre reinforced concrete increased by 18.3 MPa, and the flexural strength increased from 5.3 MPa to 9.2 MPa. These results demonstrate that nano-SiO₂ and glass fibres can significantly improve the mechanical properties, corrosion resistance, and permeability of concrete. This study offers the construction industry a high-performance and durable composite material that meets the requirements of modern engineering for building materials.
