Análisis comparativo de las propiedades mecánicas de geopolímeros que incorporan nanowhiskers de SiC y nanopartículas de TiO2
In this work, a metacaolin-based geopolymer was fabricated with 5 proportions of two different nanomaterials. On the one hand, silicon carbide nanowhiskers and on the other hand, titanium dioxide nanoparticles. Both were placed into water and received ultrasonic energy to be dispersed. The effects o...

| Sumario: | In this work, a metacaolin-based geopolymer was fabricated with 5 proportions of two different nanomaterials. On the one hand, silicon carbide nanowhiskers and on the other hand, titanium dioxide nanoparticles. Both were placed into water and received ultrasonic energy to be dispersed. The effects on mechanical properties and reaction kinetics were analyzed. Compared to reference matrix, the results showed a tendency to increase on flexural strength. Probably due to the geometry of SiC nanowhiskers and the pores refinement caused by nano-TiO2 particles. Calorimetry curves showed that incorporating TiO2 nanoparticles was a reduction in total heat (92 %) at 24 hours, while SiC nanowhiskers achieves a reduction less intense at total heat (25 %) at the same time.
