Here is an account of a large slab of granite found in the descending by Petrie
"The limestone was easily smashed then and there, and carried out piecemeal ; and as it had no worked surfaces it was of no consequence. But the granite was not only tough, but interesting, and I would not let the skilful hammer-man cleave it up slice by slice as he longed to do; it was therefore blocked up in its place, with a stout board across the passage, to prevent it being started into a downward rush. It was a slab 20.6 thick, worked on both faces, and one end, but rough broken around the other three sides ; and as it lay flat on the floor, it left us 27 inches of height to pass down the passage over it. Where it came from is a complete puzzle ; no granite is known in the Pyramid, except the King's Chamber, the Antechamber, and the plug blocks in the ascending passage."
Note the reference to the slab being boarded up so as to stop its downward rush.
Petrie was obviously concerned with momentum. So how did the plug blocks gain the momentum necessary to jam them (some of them) into the reduced dimensions of the ascending passageway.

The great amount of labour involved in quarrying and transporting such a mass of masonry as even the casing, has always been a cause of astonishment - Sir Flinders Petrie.
