Hi
I am going to build a retaining wall 1.5 meters high.
I was thinking of using concrete blocks 15cm (6inch) thick, hollow, then pour concrete into the hollows and vibrate it so it fills the cavity then use re-enforcing rods to tie the blocks together i.e. the rods go vertically into the hollows of the newly fill concrete blocks.
Can anyone see a problem with this idea? Is there a better way? Will the wall be strong enough?

Any retainer wall more than 1200mm high must be designed by a qualified structural or civil engineer.

Your plan may be suitable, but as no-one here can tell what sort of loads the wall will be retaining, what the ground conditions are, what the drainage is like, it's impossible to say. However, filling the frogs/voids of CMUs with concrete and then inserting rebar is NOT a recognised construction method and would not be permitted on a properly supervised project.
