mike232 said:So I'm looking for how tall I could make a tower of concrete, using any reinforcments, in an environment of only gravity starting at sea level. Could it get so tall it'll own gravity would effect it, the moons, or the sun's gravity, or would the bottom give out will before that?
mike232 said:I have about a Jr level physics knowledge. So my guess would be that the base of the tower would give out before the towers gravity effected anything to a significant degree, but I don't know. So before I went into the math behind the material science I am hoping someone knows if just conceptually we could ever make a concrete tower that its own gravity is significant, in the described environment.
mike232 said:For my guess on relevant equations and stuff, probibly a lot of trig in the design on the support structure. So a lot of triangles forming polygons making framework. But I also disn't initially give a base so I guess theoretically I could have a 70 mile radius at the base and then the hight would potentially be enormous. I was thinking more realistic though like a normal kind of magnitude for a tower we have made. So I guess I'm asking for the max height of a tower with the base roughly the same as the sears tower or many like a 200m base radius. But I'm more looking for gestamates like order of magnitude.
Concrete is a mixture of cement, aggregates (such as gravel and sand), and water. When these ingredients are combined, a chemical reaction occurs that causes the mixture to harden and form a strong and durable material. Under pressure, the small particles of cement and aggregates are pushed closer together, creating a stronger bond between them.
Air voids in concrete can weaken its structure and reduce its strength. When concrete is under pressure, these air voids can compress, causing the concrete to crack or fail. Therefore, the absence of air in concrete is important to maintain its strength and durability under pressure.
No, gravity also plays a significant role in the behavior of concrete. Gravity causes the concrete to settle and compact, which helps to strengthen its structure. However, too much pressure from gravity can also cause concrete to crack or fail, so it is important to properly design and reinforce structures to withstand these forces.
The composition of concrete, specifically the ratio of cement to aggregates, can greatly affect its resistance to pressure. A higher ratio of cement will result in a stronger and more durable concrete. Additionally, the size and shape of the aggregates can also impact the strength of concrete under pressure.
Concrete is commonly used in construction for a variety of structures that are under pressure. Some examples include foundations, retaining walls, dams, and bridges. It is also used in pavement and flooring, where it must withstand the weight of heavy vehicles or foot traffic.
