Effect of nanoadditive dispersing method on properties of natural hydraulic lime-based mortar
Original language description
In order to meet increasing requirements on mechanical strength of lime-based materials, modification by carbon-based nanoadditives seems as the proper enhancement strategy. However, the incorporation technique preventing clusters formation and ensuring proper distribution in fresh mixture is crucial for effective application of nanomaterials in production of construction composites. On this account, the dispersing effect of surfactant combined with antifoaming agent and its impact on mortars based on natural hydraulic lime and enhanced with multiwalled-carbon nanotubes (CNTs), have been analyzed. Dispersing solutions have been tested on foam formation, foam stability and UV-light absorption to evaluate dispersing effect. Impact of the used dispersing solution on hardened mortar samples was evaluated based on the assessment of basic structural and mechanical parameters. While CNTs dispersed in water starts to form clusters immediately after mixing stops, the dispersion stability was greatly enhanced with use of surfactant. Onthe other hand, surfactant stabilized air bubbles formed during mixing of mortars and resulted in an increased porosity accompanied by a low mechanical strength. The best results were achieved with the use of surfactant increasing dispersion effect in combination with the antifoaming agent which effectively destabilized formed air bubbles.
