Can someone ID these blocks used?

I've seen regular medium density blocks and they look nothing like these ones. I want to raise that wall to the same height as the adjoining walls however not sure what type of block that is meant to be. Anyone tell from that poor picture?

Cheers

7n dense concretes?

Hmm they could be, although Cant seem to find any with that colour they all seem grey rather than that colour. If I cant find any will just use them and probably paint the wall although thats work I never wanted to do!

It depends on what part of the UK you are in and where the merchant buys the blocks in from. They will come in many shades of grey!

They are the dense 7N ones though - there is no mistaking them

OK thanks for that at least I know what type they are now. Its not a major issue with the shade of colour just would have been nice and less work!

Also what mortar Mix would be best suited for this 3:1 a little overkill?

Also roughly 20KG in weight each!?
