I've recently tried a mortar mix that includes adding a bit of lime (just a quarter of a unit). The only thing I observed was that when first laying the blocks, the mix seems to really grip/bond to them straight away. However, when I came to remove two blocks a couple of days later it did not take too much effort to do. The mortar had not fully hardened in those two days which surprised me.
