Study on the Influence of Basalt Fiber Reinforced Plate on the Shear Performance of Recycled Aggregate Concrete Beams

Research Overview: A study published in Volume 133 of the Journal of Building Engineering (December 1, 2026) was conducted by Alaa Al Hawarneh, Samer Al Martini, Abdulla Al Zubaidi, Reem Sabouni, and M. Shahria Alam. The study focused on the effect of bent basalt fiber reinforced polymer (basalt FRP) slabs on the shear strength of reinforced concrete beams prepared with recycled aggregates. The research focuses on the interdisciplinary field of building structure reinforcement and sustainable concrete materials, which belongs to the category of building material performance and testing.

Core issues of research concern

The application of recycled aggregate concrete in construction and home decoration projects is increasingly receiving attention, but its mechanical properties differ from natural aggregate concrete, especially in terms of shear resistance, which requires additional reinforcement.

. Basalt fiber-reinforced polymer board, as an inorganic fiber-reinforced material, has the characteristics of corrosion resistance and good compatibility with concrete, and is used for external bonding and reinforcement of concrete components. This study investigates the enhancing effect of bent basalt FRP slabs on the shear bearing capacity of recycled aggregate reinforced concrete beams through experiments, providing data support for the application of such reinforcement schemes in building structures.

Significance of polymer additives and building materials industry

From the perspective of building and home decoration materials, the basalt FRP board involved in this study belongs to fiber-reinforced composite materials, and its long-term performance is closely related to the stability of the resin matrix.

. The weather resistance and stability of materials directly affect the service life of reinforcement effects in exposed environments such as building exterior walls, roofs, and structural reinforcement. Although this study focuses on the shear performance of structures, its conclusions have reference value for understanding the performance of fiber-reinforced panels in building applications. For enterprises engaged in building materials such as PVC profiles, building coatings, and sealants, the combination of recycled aggregate concrete and FRP reinforcement technology suggests a new direction for collaborative design of building envelope and structural materials. The rational selection of antioxidants and light stabilizers in material formulation design is a key factor in ensuring the long-term weather resistance and stability of polymer based building materials, which is particularly important in outdoor building applications.

Industry Insights

This study provides experimental evidence for the promotion and application of recycled aggregate concrete in building structures in terms of shear reinforcement.

. With the increasing demand for sustainable materials in the construction industry, the combination of recycled aggregate concrete and fiber-reinforced composite reinforcement technology is expected to receive more attention in scenarios such as existing building renovation and structural reinforcement of new construction projects. Building material companies should not only focus on structural performance, but also pay attention to the design of weather resistant and stable systems for supporting polymer materials to ensure the long-term durability of construction projects.
