   gb...Check your anchor bolts , they should give you a reasonable indication.

   What do you look for when you check the anchor bolts?

    I'm sorry, I thought you wanted it done the right way.

   Ed.......Usually the last place that gets mortor is the anchor bolt cavity, the mud is thicker there than  any place by many times and should set alot slower than than motor joint's.  Just go over and see if they feel solid.

   P.S. hope nobody has a cow but........many times we have put down a sub-floor the day after the block were laid with no noticeable problems then or later.

   "Usually the last place that gets mortor is the anchor bolt cavity, the mud is thicker there than  any place by many times and should set alot slower than than motor joint's.  Just go over and see if they feel solid."

   A thicker pour of concrete or mortar, by staying moist longer, will not get stronger slower.  It will get strong at the same rate initially, but will then continue to get stronger than areas that have been allowed to improperly dry out.

   Concrete (and mortar) doesn't get strong by drying out.  They get strong by staying wet. 

   If you aren't keeping it moist for 7 days you are getting much less strength than you could / than you paid for.

   David.......Your right , most of us know it and most of us just build the house when the anchor bolts feel like there solid enough to put the plates on. I  respect your obivious professional knowledge and it reminds me to  pass this knowledge on to the crews in an on going attempt to teach/inform.

   I figured I'd wait a week as posted on the package as the cure time (28 days full strength) before putting the wall on. But I'm confused since I figure each course goes up in hours as opposed to weeks, so why does it seem natural to lay many courses in a day but not to rest the weight of a wooden wall on the block?

   mortar has the psi of barely 1200 psi. correct method is to fill block with concrete around anchor bolts. if you tighten the achor bolts around mortar it will just pull the bolt out to matter how old the mortar is.

   as far as load bearing... 24hrs should be fine...  pretty sure a mortared block would hold up a couple thousand pounds within an hour without compressing the joint
