Can 2x6 be used as a beam?

A 2x6 is really 1.5" x 5.5" not 2" x 6" as the name suggests. So a built-up beam made from two 2x6's is actually just 3 inches wide. If you're supposed to use a 4x6 timber, you might not be able to substitute a built-up beam made from two 2x6's.

You must laminate them together (somehow).

Imagine a stack of sheets of paper, each sheet 5.5" x 10 feet, the full stack is 3.5" high. Is that as strong as a 4x6? No, because each sheet of paper will simply bend individually (independently). So will a pack of six 1x6’s or a stack of two 2x6‘s. That's what makes the 4x6 stronger than six 1x6‘s. Howver you may notice that a 500 sheet pack of copy paper in its package has some resistance to bowing out that the unwrapped stack does not. That is because the package holds it bound in a stack. The sheets are not free to slide past one another, so they can't bow as easily. That's what lamination is all about. It keeps the individual 1x6's or 2x6's from spreading or sliding past each other, making them more rigid. Even the aforementioned stack of paper could do alright if it were glued together effectively. The most effective way is to use glue, obviously. I am cautious of gluing to new wood, especially treated wood, because it is so wet internally, and in my experience that makes glue ineffective. I like my lumber dried a year per inch (so 9 months on two-by's, which are 1.5" thick). By the way, four-by's are 3.5" thick so you have 1/2" of thickness to make up if that dimension is critical.

However you can also lam with bolts or screws.

Now if you want to make it extraordinarily strong, steel is freakishly strong when kept on edge. Consider a laminate of

two-by

1/16" steel sheet

3/16" plywood

1/16" steel sheet

two-by

All tightly bolted together in a stack (gluing wood to steel won't provide very good adhesion). This plays to the strength of both materials, the stiff but not particularly strong wood forces the strong but wet-noodle steel into its strongest shape. And also keeps weight down since the stiffener is wood, not steel.

Can you build a shed foundation with 2x4?

You can frame a whole house with nothing but 2x4, but it's easier to do a shed, as you won't need engineering, probably. The secret word is truss. You can use them for roof, floor and even wall framing, but few sheds will need trusses for walls.

diy.stackexchange.com - How much of a shed can be framed using 2x4 lumber?

The place I work at has been ordering new machinery and it comes in with 2x4 frames. They are throwing the wood away! Anyhow, I can get all I want. So my question is how much of the shed can I do using only 2x4's? I see most bases of the shed are done with 2x8's or something along that line. I will be building it off the ground with blocks as I cannot afford a concrete slab at the moment. I would like to build more of a shop than a shed. Maybe 15x20? But my longest "free" wood is 12 ft. My current shed is a dirt floor. I could live with that if need be. My current shed is old school. I live in the country, so no certain requirements have to be met. Anyhow, the sheds bones are old utility poles. It's in an awkward spot, so I wanted to build a newer one in a different spot. The walls are tin. No plywood on the walls. Roof is tin as well. I'm just trying to see if the wood I get at work will be enough to cover 90% of the cost. I want 20ft long, so can I build 2 ten ft walls and join them together to make 20ft? I understand that may not be proper, but it's a shed not a house.
