Medium weight concrete block with 48% recycled aggregate including recycled wood, allowing them to claim the block's carbon footprint is -2kg per tonne. Used extensively at The Shard and London Olympic stadium (among other places).

I’ve not come across these 

But cost will determine wether they are viable 

I never like this request a   call back

Hard sell 

At the end of the day It’s a concrete block 

Under 40p Would be worth further investigation

Really down to the cost, they may promise the earth, but if there £1.50 each I can’t see anybody wanting to use them.

@Russell griffiths I suspect it's a question of the market you are catering for.

The Shard used 140,000 of them, presumably because in the context of a project like that, being able to say the blocks were carbon neutral was worth more to them than an extra £140k (or whatever it was).

The blocks also seem to have a slightly better acoustic reduction than standard medium weight, but perhaps not a big factor in most cases.
