Half bricks and calculation

[kris]

Hello All

I`m new to the forum, and I`m not sure if it`s the right place to ask (moderator please relocate to the right section if needed).

Looking through the forum but I`m so far unable to find how to "calculate the amount" of bricks needed for the dome regardless to the diameter.

Also, i noticed half bricks are not available in UK? 114x114? the only placed i`ve seen them where in on US web or it might be actuarial Australian web.

Does it mean that all you guys cut the 230mm in half?? 

Thanks

Hi Kris
I purchased 200 230x114x64 firebricks for my oven and cut them in half which was surprisingly easy with a 9" grinder and a diamond disc. Bricks soaked in a bucket of water for maybe a minute.

My oven is 900mm inside diameter.

I am hopefully going to finish the chimney and outer arch this weekend while the weather is good in essex. I have about 30-40 bricks left i believe and will use about 20 to do the arch and chimney.

I also used these bricks for the floor

Hope that helps
