The simplest way is by Size and shape.
Crushed coral is usually much bigger than sand
(CC is usually 2-5mm, whereas even "coarse" sand is usually <2mm, and fine sand is <1mm.)

Also Crushed coral looks like it's name--it looks like bits and chunks of broken shells and rock.

This website http://www.caribsea.com/pages/products/aragalive.html has some good photos of different types of (commercial) sand and crushed-coral.
 
Welcome to REEF FRONTIERS! Live sand = small grains like sand on the beach.
Crushed coral = bulky small rock-like pieces. picture getting dried dead sps coral and smashing them into small bits.
