Hi,
I have a patio laid with railway pavers which have quite large gaps in due to their size and wavey edge. They look to have been laid directly on the ground and are very solid so don't intent on pulling them up. They are a good two inches thick. Due to the amount of weeds growing I need to fill the joints with something suitable which is what I need advice on. Some of the gaps are over an inch wide.
I have some Tarmac weed free paving sand (3 bags) - is this any good?
Could I mix this with some sharp sand and cement mix (2:2:1 maybe?) to get a good solid joint mix?
Hope the image links work:

Any advice appreciated.
