With the help of a hydraulic press, we will test the strength of concrete and reinforced concrete

Your concrete did not have the correct proportions of aggregate to make strong concrete, that's why it crumbled so easily. There is a lot of science that goes into the proportioning of the elements that go into concrete, change the amount of one of the materials and it can have a significant affect on the strength. In addition if you are trying to add reinforcing to strengthen concrete you have to consider what strength you are trying to reinforce for, and the reinforcing configuration not only has to match that but it has to be able to transfer loads from the concrete to the steel. The reinforcing layout in the video is incorrect for reinforcing against compression, and you would have to use much smaller types of reinforcing in order to be able to transfer loads from concrete to reinforcing.

Watching this video "reinforced" certain knowledge I had when I studied mechanical engineering. They're fine generic demonstrations for what you're talking about. But now I'm yearning for an in depth video(s) of how engineering concrete is done, and would love to see videos of such things with proper hydraulic press demos that explain "you see, this is why we don't expect bricks to hold things in tension. or see the real difference between using aggregate with rough surface vs smooth or porous vs non." (not sure if those differences actually matter much vs size and shape, just pulled some properties out of my head).

It is unsatisfying on so many levels for a civil engineer like me to watch all the blunders made. First of all concrete being mixed wrongly, later no curing provided to the concrete, and reinforced concrete beam subjected to compressive load, whereas we generally test it for flexure.

Roman concrete vs modern concrete would be interesting. The roman concrete uses ash from volcanos so not the easiest to source, and uses much less water. Obviously modern reinforced concrete is much stronger, but for the concrete itself it's still interesting - especially if we want to avoid the reinforced part to avoid rusting and maintenance. Roman concrete will last thousands of years while reinforced concrete will eventually fall apart as it rusts from the inside out.
@billj5645
@billj5645 2 жыл бұрын
Modern concrete uses various types of ash to supplement the bond of cement as well as other chemicals, there is a lot more that goes into concrete besides cement, water and rock. Modern concrete mixes have been made approaching the compressive strength of steel. To the average person concrete is what they see in a sidewalk but sidewalks are the bare minimum that will become gray and hard, the concrete used in buildings where significant strength is required is very hard stuff. Hit a sidewalk with a hammer and big chunks break off, hit a piece of structural concrete with a hammer and the hammer bounces off, maybe without even leaving a mark on the concrete. This stuff may be at least 5 times the strength of a common sidewalk.

You are comparing apples to oranges. The "concrete" mix was apparently not standardized for all three samples. One mix had gravel, while the second mix lacked gravel. The cube also had no gravel. The ratio as well as the water content was not given and may have varied. How was the curing done? The reinforced vs unreinforced samples should have been tested as beams, for example with two supports at the bottom and one load in the center. A sand and cement mix is not concrete, but mortar which is much weaker. Your cube only had about 860 psi of compressive strength. The antique concrete cube performed comparatively well with about 2500 psi, which you could have reached easily with modern concrete after 28 days.

I would like to see an iron pipe or steel pipe filled with concrete. I think it will be the hardest thing to press. Will it? Reason is that the metal pipe will hold the concrete and the only way to crush it is such force to make the concrete inside to tear the metal. OBS, the cement at 5:00 is not a concrete and it starts to at 2.6tons about it despite it got up to 6 tons, i guess if it was in a build that first tear would already be the doom. Would be really nice to see, the tests for cement, normal concrete, concrete with mixed sizes of rocks, and of course each mix before now with some frame in it. That would cover the most common combination and get how strong are each. Really would love to see such experiment.

To have credibity in your results you should have an horizontal face . In your case , the shape of the dry concrete isn't the best because in the first experimentation the force apply on the paving concrete induces shear forces ... and they are lot of mistakes in dimension and how you apply forces . You have to speak about the other test like "cône d'abram" and " air occlue" and the different type of normes

That's unscientific ~ you can't just create concrete using a random amount of cement and water. try testing the old concrete to know it's strength then to recreate it using the correct components ratios of modern concrete that would by interesting. or you can test the concrete from a different concrete factory to know which one is better.
