Don't use cement on the block paving as you will stain it.
It is special kiln dried sand that goes between the joint.

Kiln dried sand will cost a bomb. It might be useful for using as a
filler with the sort of resin used with fibre-glass.

All you need to do once you have put weed killer down (as you don't own
a British made diesel) is brick-sand, a warm, sunny day and a soft
broom.
