I forgot another important reason why Portland cement is preferred over lime these days. Lime takes a while to set (a few days?), cement sets faster.

> Lime takes a while to set (a few days?)
Up to 30 days to set, and depending on the type of lime (hydraulic or non-hydraulic) and form/process (putty, hot mix, etc.) up to a year to reach full hardness.
Cement will still take many days to reach full cure time (measured in increasing PSI ratings)

But it will be set enough to keep laying bricks tomorrow. Lime on the other hand takes a bit more thought. It is doubly true if the weather is cold
You aren't contradicting anything. MOST of the strength is achieved in 24 hours or less.
