Asset management

In a sixty year period, three investments of $10 m (total investment $30 m) result in a similar asset value to a single complete replacement /rennovation of failed asset (investment of $50 m) afer thirty years. (Both scenarios depreciate at 1% anually.) This image links to a Tableau dashboard, where the data may be viewed in more detail.

The porosity (n) of a mixture is the ratio of the volume of void-space to the total or bulk volume of the mixture. It is closely related to the concept of void ratio (e) where void ratio is the ratio of the volume of void-space to the volume of solids. n = Volume of voids/Total volume of mixture = e/(1+e)
