Lime Mortar & Portland Cement

Lads, Whats the different in terms of drying time for Lime Mortar and Portland Cement? Lets say its half brick thick and English Bond. I think as below, assume brick thickness is 65mm and mortar thick is 10mm. 1. Lime Mortar - 6 layers of brick / day for curing (About 450mm of height) 2. Cement Mortar - 15 layers of bricks / day for curing (about 1125mm if height) I mean the restriction for maximum of bricks can do as the mortar need to be cured before more bricks can be built vertically Regards, Mike Planner
