Dense concrete blocks as BBQ base

I have some breeze blocks left over & was wondering if I could use them as base for a wood fired barbecue (think South American - not a pizza oven).

Could I use these blocks as base? Maybe with a lintel at the top row opening & large pavers on top?
Plan would then to use fire bricks for my coals.
Worried if the heat could be enough to cause the DCB's to crack or even explode. I read somewhere that wet concreate blocks can turn the water into steam & cause the blocks to explode!
