Research on the Influence of Microfibers on the Physical Properties of Building Geopolymer Mortar
The microfibers with different mass fractions(1%,2%,3%)were added to geopolymer mortar,and the physical properties of geopolymer mortar were systematically tested and analyzed.The results indi-cate that the addition of microfibers significantly enhances the crack resistance and mechanical strength of the mortar.Specifically,the addition of microfiber with a mass fraction of 1%achieves a good balance be-tween cost and performance enhancement,particularly in terms of flexural and compressive strengths.Fur-ther microstructural analysis reveals that the network formed by microfibers within the mortar effectively bridges internal micro-cracks,thereby inhibiting shrinkage and enhancing overall stability.Additionally,considering the economic aspects of building materials,the effect of microfiber addition on cost-effective-ness was also discussed,providing practical references for budget-constrained construction projects.
