Question Keeping Concrete out of Cells

Hello All:

Building First Oven here is Takoma Park Maryland. Got the cement blocks in place last weekend and filled the required "core cells" with concrete for strength. I hope to build the form for the first concrete layer this weekend.

I have no idea if this question is way off the mark, but here goes:

In pouring the intial concrete, can I expect that a bunch of it will pour through the open cells on the top of the last layer of cement blocks? It would seem like there would be a good deal of waste if much of the concrete pours through this rather wide openings.

If anyone has a trick or technique to keep this from happening, it would be much appreciated. I will be snapping some pics this weekend, and hope to post early next week,

Thanks very much in advance,

Jim

Jim,

I know a lot of people who just stuff their empty cement bags in the cells to fill the void or being one who went overboard on the cautious side, I filled every core with cement. I believe most builders opt for filling the empty cores with the bags or other loose material.

I filled my empty cells with the empty bags from the Sacrete that I used to fill the other cells. And then a bit of sand/gravel. Not much.

You can fill em with just about anything to keep the hearth concrete from running into them.

Sand, gravel, dirt, newspaper, a time capsule.... whatever is available.

Congrats on the beginning of your oven! It's a heck of a fun project.
Remember to post pics.(We like em around here)
Good luck, and keep asking questions.

Jim,

The plans recommend that you use old concrete bags to fill in the cores you don't want filled. I read there are plastic "fillers" but haven't found any yet.

Good luck
Dick

WHoa....those responses were quick and much appreciated. I guess a little common sense goes a long way....should have thought of that myself.

Thank you for your replies. I will post as I go.

Regards,

Jim
