| description | Nanotubos de portlandita obtenidos mediante un proceso que comprende las siguientes etapas: a) hacer reaccionar cloruro de calcio con óxido de calcio en solución acuosa, obteniendo de ese modo una dispersión acuosa; b) alimentar como tal la dispersión acuosa obtenida en la etapa a) a una reacción hidrotérmica, obteniendo de ese modo nanotubos de portlandita.
The present invention describes the preparation of nanotubes made from portlandite, the naturally occurring form of calcium hydroxide, Ca(OH) 2 . Portlandite nanotubes are obtained by a process comprising the following steps: a) reacting calcium chloride with calcium oxide in aqueous solution, thus obtaining an aqueous dispersion; b) feeding as such the aqueous dispersion obtained in step a) to a hydrothermal reaction, thus obtaining portlandite nanotubes. The invention also concerns the use of the portlandite nanotubes as a component for cementitious compositions to provide reinforced mortar or concrete. |
