Early in Cell Blocks, you'll use a vent to crawl past a stack of crates. Exit through the vent inside this tunnel (not the left exit), and you'll come to a courtyard with several thugs and an improvised bomb. Detonate the bomb with the Crypto Sequencer, then drop into the pit to find this clue on the ground.
After receiving the Batclaw, you'll backtrack on your way to the exercise yard. When you reach the room where you dropped the elevator with frayed cables, leap over the flames on the lowest floor. Pull the vent with the Batclaw, then crawl into another room where this clue sits on a shelf.
When you return to the area where Catwoman sent you on a detour, you'll use the Batclaw to rip away a vent cover. Enter that vent and crawl forward, but stop before exiting. Those little bits of rocks in front of you are actually another clue.
