I’m looking to build a large brick smoker/grill unit soon. It will contain an area for burning down the wood into coals, as well. As I’ve checked with some BBQ websites to explore the topic, it has come to my attention that one doesn’t just use regular mortar when dealing with intense heat. It was stated by one man that Portland cement should be used in conjuction with a type of clay compound findable at the local brickyard in order to prevent “exploding” upon first fire. Now I’ve seen cracked units before and have noted that heat must have been the cause, but “exploding” seemed like a strong word to use.
In any event, if an additive should be used — I’ll be looking for an alternative. I live in Bolivia (that’s in South America, in case your HS geography class has failed you) and the availability of these items is basically non-existent. Our area is a brick-producing zone, so that type of clay is readily available if one owns a shovel.
Does anyone have experience in this area? Is straight Portland with sand going to work fine? “Season” the unit before taking it up to full heat? Additive of some kind?
I’d sure appreciate any and all comments.
Here’s to smoke in yer eyes…
