ABSTRACT
The calcium hydroxide nanosols are obtained in a proprietary manner that uses complex reactions between water, metallic calcium and ethanol, whereby it is important that an exactly defined ratio is guaranteed between the different components. An excellent way to characterise the stability of nanolime dispersions is to measure the sedimentation rate using an ultracentrifuge. Liquids with a low surface tension generally tend to wet solid surfaces better. Due to the use of alcohols as solvents, the nanolime dispersions have a lower surface tension than water, resulting in an excellent wetting behaviour. When nanolime dispersions are placed on glass plates, for example, complete wetting takes place. Nanolime generally displays good penetration behaviour with depths of several centimetres. Similar reactions take place during the carbonation of the calcium hydroxide formed after the evaporation of alcohol from nanolime dispersions.
