Abstract
The effectiveness of corn straw Fiber, organic polymer latexes, organic polymer latexes and corn straw Fiber blending on vibration damping properties of cement-based materials were studied by filling organic polymer latexes, and corn straw Fiber. The functional mechanisms of various fillers were discussed. The experimental results showed that the vibration damping ratio of cement-based materials with organic polymer latexes is 149.77% higher than that of pure cement-based materials, the vibration damping ratio of cement-based materials with corn straw fiber is 152.58% higher than that of pure cement-based materials, the vibration damping ratio of cement-based materials with organic polymer latexes and fibers blending is 191.08%, also higher than that of pure cement-based materials. The impact of corn straw Fiber and polymer latexes modification on the microstructure and mechanisms were analyzed by FTIR and SEM.
