Granules? That would be the concrete, then! Never heard it refered to as "granules" before.
There have been basic forms of concrete for over 2,000 years although it hasn't always been used for edge restraint. On some of the old, unreconstructed sett-paved roads that still exist - such a sthat going over the Pennines near Littleborough, the edge restraint was formed by using bigger and/or heavier and/or longer "kerbs" at the free edges, and bedding them into gravel or similar and then banking earth against them.
9kg to 18kg really isn't heavy. A basic concrete road kerb (152 x 255 x 915mm) weighs in at around 70kg and the big old granite kerbs we used to lay all around Liverpool would be 3 or 4 times as heavy.
