A board foot is a unit of volume equivalent to 144 cubic inches. To find tons, you would need to know the density of the particular wood that you are interested in.

====================================================

Boardfeet is based upon nominal dimensions. For example the nominal dimensions of a 2x4 is 2" x 4". It's actual dimension is closer to 1 1/2 inches x 3 1/2 inches. So there will be some error in the calculation if you are attempted to determine the weight of dimensional lumber. Southern Pine weights approximately 40 lbs per cubic foot. There are 1728 cubic inches in a cubic foot. There are 2000 lbs in a ton. therefore the weight of one board foot (conservatively because of the nominal dimensions) is:

(40x144)/(1728x2000) tons per board foot.

Sorry , don't have a calculator handy.

Another way to do it is that there are about 12 board feet in a cubic foot. So a board foot would weight 40/12 lbs or 3.33 pounds.

3.33 pounds is 3.33/2000 tons. !! a lot easier!!

Slump check does not measure strength. It measures workability. Workability is the ease with which concrete can be placed in position.

Correct as far as it goes! Slump refers to workability however it is also, all telling as to the water content of the mix. The more water, the easier it will work! Problem becomes, too much water will increase the porosity making the concrete weak and susceptible to early degradation because contaminates are able to enter and commence corrosion of embedded steel.

A concrete that is easy to work that has a high water content [ more than .40 ] is known for shrinkage cracking due to rapid evaporation of the high water content. These cracks caused by rapid loss of water decrease compressive strength and invite early corrosion. This type of concrete also experiences, curling and ASR as well as efflorescence in a very short time period.

Strength is a function of correct hydration, slow internal curing and careful design of a mix for the intended service criteria and not a whole lot to do with slump!

Shelter provides protection. Protection from weather and predators. Without shelter you may freeze in the winter or become dinner for an animal. Shelter may come in many different forms, for example caves, trees or man made structures. It is my opinion that shelter is not needed to survive per-say, it is needed to extend one's survival.

Stone is most definitely not a good thermal insulator. It changes its temperature quickly with the surrounding environment. In fact, stone is a thermal conductor and will pass heat or cold right to the adjacent materials.

Many individual never thought of the work our garage door does - lifting and closing a large door every day, over and over again.. The fact is, your garage door opener really doesn't do much work, because of a physics helper, the spring! Springs are utilized as the door is lowered, and the springs are stretched out (the motor literally pushes the garage door down). When it is time to lift the door, the springs do 95% of the work as they recoil and pull the door back up, leaving the garage door motor to do little more than wind up the loose cable or chain. This is why most garage door openers are rated at only 1/2 to 1 horse power - it doesn't take much power to lift up a garage door that is being pulled up by stretched springs.

Not really, but if you consider the versatility of dome construction you don't really need more.

Monolithic domes can be designed in some very interesting freeform shapes.

And geodesic domes can be customized and personalized so they don't look like "cookie cutter" or prefab homes. Personally, I love the look you get when you cluster several smaller sized domes. This is how I want to design ours when we finally get around to it. I also plan to incorporate a sunroom/screened dome.

There are other types of Dome Homes.

Without getting into great detail: Geodesics are made of sets of triangles (panels) joined together. Monolithic (mono = one, lithic = stone) are formed of one material (often shotcrete or other concrete) placed in some type of dome shaped form.

Monolithic probably covers some ancient mud dome techniques so I will throw them in.

Other types of dome homes include:

Brick, used mostly in ancient times. But I'm sure someone has done one since. I seem to recall a church in Timbuktu that was somewhat recent ('70s?).

Sand bag. Being promoted for 3rd world locations. Layers of sandbags (often long 30'+ ones) with barb wire placed between them to keep them from shifting. The results tend to be quite durable and cool. Doors and windows are made of sandbag arches. A nice bonus for war torn areas: They are pretty much bullet proof.

Wattle, thatch, grass, etc. Africa mostly. From huts to quite large structures.

Log. Saw a picture of one once, not very detailed photo, but a dome it was.

One I haven't heard of, but a cool idea:

Take a surplus (scrap) natural gas or LPG steel "dome" (more of a globe) modify it (cut in half?) cut windows in it, poof, really big house... Finding a spot where you could place a several (hundred?) ton metal house might be a little tricky. Maybe Mr. Gates could use a new garage?

Yes, there is. It is not large. Some people and companies want some new piece of concrete decorated. Like a home patio. Look in the Yellow Pages in your city and see who is already out there in the market.
