If you lite a fire inside a concrete box, the heat will be sucked into the concrete and eventually radiate from the outside at a lower temperature but, if you insulate the box the heat will stay inside the box making the inside much hotter so full combustion can take place.
So if you build a rocket stove using a fire brick box, you would need to insulate the back side of the bricks, the fire will first have to heat the bricks but the insulation will hold the heat back and stop it radiating into the air.
Now if you have a concrete floor the fire would have to saturate the whole floor before it could start heating the box to maximum potential.
So on its own, pea gravel wont be able to absorb heat or store heat very efficiently but, if you add sand and cement to the gravel it would become a solid dense mass.

We find this kind of rampant individuality very disturbing. But not this tiny ad:
