42.5 lbs. (19 kgs.)
carefully
143 ton according to my calculations.Thank you
it can't hold very much weight
Bricks have pores because they are made from concrete and concrete is a porous material. Bricks could be made of non porous materials but then they would require a different, and more expensive, medium to hold one to another, where concrete is now used in building to hold bricks together.
There is effectively no limit to the amount of weight that aluminum can hold, if you use enough aluminum.
have many folds
carefully
Light. Sorry, I don't mean to be flippant, but "lightweight" just isn't enough to answer this question. You're going to have to be more specific than "lightweight".
If you place it on the point of the egg then yes an egg can hold the weight of a cinder block. The egg has to be perfectly vertical. You can also try to smash an egg from the points with your hand, and you will not be able to.
you mean will it not squish under load? I would say so, it takes alot of force to squash a can (about 20kg+) and Im sure a block like this weighs alot less.
New concrete will need to cure for several days. Depending on how much weight it is going to hold, this should be postponed as many extra days as possible.
The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.
The weight that concrete can hold before breaking depends on factors such as its composition, thickness, and the conditions it is exposed to. On average, concrete can typically withstand compressive strengths ranging from 3,000 to 7,000 pounds per square inch (psi) before failing. However, it is important to consult with a structural engineer to determine the specific load-bearing capacity for your particular application.
The amount of weight a concrete driveway will hold without doing damage would be determined on many factors. For instance, consolidated area of weight..ie.#'s per sq. foot, concrete strenght, amount of reinfocement in concrete, compaction of soil under concrete when placed, thickness of concrete, etc. Most driveways should be able to handle a concrete delivery truck if the drive way doesnt have any abrupt edges that truck must cross and the tires stay a reasonable distance from the edges..Hope this helped..and enjoy the pool if that is your project
Concrete forms are devices used to hold concrete in a prescribed shape until it dries. They can be made out of anything strong enough to hold the weight in - many of them are made of plywood, but they've also been made out of steel, aluminum, other pieces of concrete (oil them and the new concrete will just pop out) and even just a hole in the ground.
they have concrete in them because the concrete has to hold it together
There are too many variables that are not quantified in the question to answer this. What kind of concrete? (There are different kinds.) Is the concrete reinforced? How is the square of concrete supported? What is the nature of the load and how is it distributed on the slab? We could go on.
