Not quite making good but..
I fit boilers. Often exactly where an old one came out, leaving a "balanced flue" hole 9inch by 12inch or bigger. To date I've always bricked or blocked with mortar, and fixed the new boiler the next day. Often the new fixing bracket goes right across the old flue hole.
I'm wondering if I could use this stuff:

with carefully cut medium density blocks? Boilers weigh say 50kg. Often you only have a row of 4 screws, or fewer. The setting time of half an hour would mean that I could put the boiler up the same day.
I haven't used these blocks before - is there a better name for them? I want something I can put a diamond core through reasonably easily - ie more like softish brick, than padstone hardness!
