why so many dislikes? this is actually pretty interesting for architects and engineers. it shows two things: 1) self-Consolidating concrete 2) principle of communicating tubes it proves that the correlation between those two are now possible. this is actually huge... but what do i except from youtube comments... dislikes come from the same people that say something like: why do i need math, i have a calculator on my smartphone.

The point is no use of vibrators, there is no segregation due to high water content, and what they were able to achieve here is a structural Engineer's dream...to have a homogeneous substructure without any joints.

It's a self consolidating concrete. In typical concrete, you usually require some type of vibration to consolidate the concrete (to place it). And you cannot vibrate it so much to place it like it is shown in this video, otherwise you'll get problems with segregation of agregates and other stuff which will ruin the design. The example here shows a concrete that does not requires an input vibration to consolidate and that places itself like a liquid (without having too much water - which is also a defect). Pretty much everything we want from a good concrete.

Actually if you do that, the coarse aggregate will pile up and the paste will just run off or as macun said, it will segregate. This is not your grandpa's concrete. It is a high tech work of art.

Self consolidating concrete is NOT just watered down 3000psi concrete! It typically breaks at well over 6000psi in 28 days. It is made to flow by careful mix proportioning and through the use of High Range Water Reducer ( super plasticizer ) plus a few other goodies. What most don't appreciate is that it runs like water yet it doesn't segregate. SCC is to normal concrete what a Lambo is to a Kia. A well done SCC mix is far superior to normal concrete in almost ever way.

If this video showed cement not concrete then why is it in a concrete truck and flowing like concrete? Cement is a powder. Are you implying there is no water or super p in here? I can clearly see crushed rock in there. And guaranteed there is sand,water,admix maybe even entrained air. Hell probably some delvo seeing as it's a demonstration and you shouldn't want it to set.
