Core filling retaining wall - pour heights

[Moonshine]

Does anyone know of any guidance on how high each pour of a core filled (200 mm) masonry wall should be? 2 blocks, 3, 4, more?

 

The walls will be tied, but they won't be supported from the outside.

Difficult one as there are a lot of variables, number and type of ties, mortar mix etc. but i would be working on around 1m per pour with unsupported walls

You will need to compact the concrete with a poker which is where it can go wrong.  900mm would be the max I would go to but if 450mm is practical then even better.  Leave for a few days for the mortar to go off before pouring.

Just to help, 10.4N blocs, M6 mortar, ties at 600mm cts horizontal, 450mm cts vertical.

That should be a pretty tough wall, as above give the mortar time to go off and bring the level up slowly and evenly - assume you are using a pump so work your way around and bring level up approx 1 foot at a time, this means you can be less harsh with the poking.
