‘Integrated Micro And Nano-silica In Advanced Composite High-strength Mortar For TRM System – Nature’

Nature Nov 27, 2025

This study presents the development of a high-strength composite mortar for Textile Reinforced Mortar TRM systems through the synergistic integration of micro-silica nano-silica silica sand and hybrid fibers. The combination of steel and basalt fibers significantly enhanced the mechanical and bonding performance of the mortar. The optimized mix achieved compressive split tensile and flexural strengths of 70.335ampnbspMPa 8.03ampnbspMPa and 19.63ampnbspMPa respectively while demonstrating improved bonding behavior with an 80.5 increase in splitting bond strength direct pull-off bond strength of 8.5ampnbspMPa and pull-out bond strength of 7.0ampnbspMPa. These improvements are attributed to the densified microstructure and refined interfacial transition zone resulting from the pozzolanic reactions of micro- and nano-silica. The findings confirm that the combined use of multi-scale silica materials and hybrid fibers produces superior mechanical strength durability and adhesion making the developed mortar a promising solution for retrofitting and strengthening applications in modern construction.
