Minimum thickness of concrete wall?

[spikplanka]

What is the minimum thickness a concrete wall can be to bear its own weight and not topple over from a gust of wind or if someone happens to bump into it?
Assuming a straight and flat surface as well as a height of approximately ~2.4 meters and not needing to support other floors, etc.

What is the minimum thickness a concrete wall can be to support its own weight and not fall over from a gust of wind or accidental bumping?
Assuming a flat and level base and a height of about ~2.4 meters and not required to support additional floors, etc.

So a 2.4 m high wall, or is there something at the top supporting it (like a rafter or similar)?
For a 2.4 high wall, I would say if it's just straight, you'll need a fairly thick wall to make it stable.

I would probably aim for a double course; if it's brick, a double brick thickness. This way, you can also "turn in" the brick on the short sides.

If it's a cast wall, maybe it can be thinner, the reinforcement will help keep it upright too: So about 10 cm might be enough then.

Found an English site: They recommend 9-25 cm thickness.

The conditions involve trusses, etc., which stabilize. Casting on-site. I thought it is most guaranteed to block sound.

Historically, s-shaped walls were built to increase load-bearing capacity and save materials.

For sound blocking, isn't a thin hard concrete wall not the best? Hard concrete can spread sound very well (as anyone who has lived in an apartment unfortunately knows).

I saw a drawing of a sound-insulating wooden wall where all the vertical studs were overlapping, which seemed effective though.

In May, for sound blocking, isn't a solid concrete wall the best? Hard concrete can spread sound very well (as everyone who has lived in an apartment unfortunately knows).

I saw a design of a soundproof wooden wall where all the vertical studs were staggered which seemed effective though.

For sound insulation/blocking, concrete is superior to wood.

This concerns sound from outside in low frequency bands due to reflections in the surroundings creating a maximum point at the location.

A commonly occurring thickness for apartment-separating walls in concrete in newly produced apartments is 180mm. This meets the requirements for construction, fire, and sound.

The equivalent lightweight wall when there is no load-bearing requirement is usually a fully insulated double stud frame 70x2 with two layers of drywall on each side.

Some additional information came in, making my post a bit unnecessary. 😃
