In the steps ahead you will learn how to build a great fire pit that is easy to build and very cheap to make.

I'm sorry for my English, and I hope everything is understandable.

Have fun building it!.

Step 1: Dig a Hole

You need to dig a hole about 50 cm deep.

I chose to make it shaped like a square.

Step 2: Mix the Concrete

Those are the ingredients I used to make the concrete:

15 kilo portland cement

45 kilo sand

30 kilo aggregate

you mix it all together and add water until it's all wet.

Step 4: Patio

For the patio i needed to make cement again. This time i didn't use aggregate because i wanted it to look smooth.

You should use 10 kilo portland cement and 30 kilo sand, mix it together with alot of water because it's easier to use this way.

Use big stones and place them around the firepit, between the stones put some re bars, and then pour the cement.

Let it dry for about a week, wash it with water twice a day to make the concrete harder.

*If i could do things differnet, I would put some small stones between the big stones.

I love the idea, yet the square shape looks like a pig to clean. Methinx better suited will be a dish shape, with enough of a base diameter to get a shovel in and out of, easily.

Umm, did you research Concrete and it's use in high temperature applications?

Please people, don't follow these instructions. Regular concrete is not suited for high heat, you MUST use a refractory cement mix in order to mitigate the water trapped inside the concrete from exploding (think boiling water vapor molecules), and sending shards of aggregate (and the rebar) into the flesh of your party guests.

Seriously, this is a big No-No.....

Also, cement is very caustic and can cause skin burns if you handle it without protection.

Just a heads up, be very careful when you have a really large and hot fire near concrete as it can cause it to explode if it has not fully dried and or it has rained recently. This is as a result of the air pockets that are always left in the concrete, when headed the moisture in those pockets is turned to steam and expands. My cousin still has scars from this happening.

Wow!

Wow, I love this! It fit in so well to the natural surroundings!

i'm glad you enjoyed it :]

Awesome fire pit. Very nicely done. Where do you live? Your clay is so sand like. I live in Ireland and we don't have clay like that so I'm intrigued...
