Masonry wall construction (Bill Allen)

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Yes, that's right. What I meant was "...closer than or equal to 24 inches,
in other words, closer than 32 inches" (a picture speaking a thousand words,
I suppose). However, I do know that not *all* Contractors in the Central
Valley use open-ended blocks, for whatever their reasons.

I do appreciate your observation, Bill.

It's been my experience that grouting "closer than 24 inches" implies that
grouting is at 16" or closer. Here in SoCal, most (if not all) blocks are
open ended, sooo....grouting at 16" IS solid grouted whether you like it or

||In regards to the "solid/partial" grout question for construction in
||California, we will typically design as "solid" if rebar
||spacing is closer
||than 24"o.c., as we've been told by a few masonry contractors
||that at such a
||close spacing, it's tough to keep the wall
||"partially-grouted". I don't know
||if this view/practice is held by the "majority" of contractors or not.
||Hope this helps.

||I need some advice regarding regional masonry wall
||construction practices.
||As I understand it, CMU walls constructed in California are
||all grouted
||solid.  No partial grouting is used regardless of applied load.
||Is this true or false?
||(The traditional rationale has been that all the seismic
||research has been
||done only on fully grouted CMU walls.)
||What is the practice of using ladder reinforcing as opposed
||to rebar in
||intermediate bond beams?
||What is the practice in Alaska?
