Filling between broken concrete (crazy paving)

I have laid my broken concrete piece out and filled the cracks with mortar and lightly sprayed it with water but it has cracked where the mortar mets the concrete pieces and is crumbling away What am I doing wrong ?

Any slight movement will create cracks.
Unless your broken pieces are bedded in concrete it will always crack.

I cannot see your mortar being successful, as mentioned need to be set in concrete. Have you thought about soiling between pieces and growing something like thyme between them. Low maintenance and smell great when you walk on it

I had this problem, and solved it by taking to the offending pieces with a sledgehammer. When broken into smaller pieces they bedded down nicely and haven't moved again in 15 years.
