The mixture of sand and cement for laying bricks

Concrete is normally estimated in cubic metres
Convert all figures to metres and multiply
3 x 3 x 0.125 = 1.125 cubic metres
Plus 10% for shrinkage = 1.24 cubic metres
10 bags cement
0.7 cubic metres sand
0.86 cubic metres of stone
All assuming you want a strong mix

no, not enough actual cement for the mix look into getting more.

Hi.
All you need is bricks and cement.
Use perforated bricks or regular 65mm bricks for the support. A light oven may be built on an U shaped support (you will need to make some structural considerations about the weight). Moreover the U shaped support on top requires an armed concrete slab adequate to support the chamber. If you are not sure about structural performance, build a solid support block of bricks.
Make sure that the support is adequate for the weight of the heavy chamber. If the oven is big, then lay basic foundations or build the oven straight on the ground.
For the chamber you must use refractory bricks (fire bricks). You have different choices of design. A common shaped that do not require armed concrete parts is the igloo style chamber. Leave space for the chimney on top of the chamber.

Hi, As with most shower trays, you must bed the tray down onto a suitable floor ( ie; solid and dry) surface using a bedding down mixture. Weak mix sand and cement is ideal for this purpose. Mix sand and cement at a ratio of about 5 or 6 to 1 and spread out on to the area where the tray is going. NOTE: it is important that the mixture is spread out evenly and touches all of the underside of the tray. Make sure you seal the floor a day before using a water and PVA glue sealant mixture so that the mortar will stick. Tap down the tray BY HAND or by using your fist, and use a spirit level on all four edges until the tray is completely level ( or as near as you can get it) I have provided a link for you with the full installation instructions. Hope this was of help to you.

well if your fingers stick to the cement its very cold? however iv layed bricks in the frost using frost profer in the cement and i coverd the bricks with sacking to keep off the frost over night,,,you cant lay them very high three rows tops in a day,,,but if you use accelerator in the cement mix it will still set before it freezes ,,,,you still build houses in winter you know? it just takes a lot longer to get them up?

Yes you could use special Fire Bricks & Cement. In fact any fireproof or Code Rated material can be used.

Hey Paul,

I'll give you the rundown. First, for a driveway, I'd have to advise using a pretty thick slab of concrete beneath the brick. The concrete part of it should be done professionally. But I live in an area with lots of rain (hence, Mud), might not be a problem where you are. Anyway, here you go:

1. Clear the area so its smooth. Grade it if necessary.
2. After clearing the area, set the perimeters with string or with 1x4 boards. This keeps you from going wide as you lay the bricks
3. Get a load of sand and spread it evenly over the area. This can be done easier with two people and a long 2x4. The depth should be at least an inch. This makes leveling the bricks MUCH easier. Keep some aside for filling in the spaces between the bricks. Keep it dry too.
   
4. Start at one end and start placing the bricks. As you advance, you'll be on the bricks, not the sand.
   
5. Have a straight edged board handy to level them. Use a rubber mallet to tap them down. Consider the spacing between them. Use a scrap of 3/8 wood or something like that to keep the spacing consistent.
6. As you place more bricks, get up occasionally and eyeball your work.
7. After they are laid, you'll need to hit a home improvement place. You are looking for a glue (powdered) that is mixed with your left over sand to set the bricks. Ask someone there, they will know.
8. You mix it in with the sand and dump it in the middle of the bricks. Then just sweep it over the entire area until the spaces are filled. Then sweep off the excess.
   
9. Once filled, lightly spray water over the whole drive. This activates the compound. Once dry, you have a driveway.

If you do concrete it first, you'll only need enough sand for the space fill.

Hope it turns out great. I love brick drives.

you will have to send some pics for me to help. I do this type of work.
