What happens here

Using a simple diagram comparing 'Skinny' and 'Wide' concrete forms, the presenter explains that just like with water, the pressure exerted by concrete in a form is determined by the height of the concrete column, not its volume or the width of the form. Both skinny and wide forms at the same height will experience the same pressure at their bases.

Goal: Explain that concrete pressure on forms depends on column height, not width.

What they say

Hide

stream longer. Same size hole and same column height of water. As you see the small tube dies faster and this has more continual pressure. So, just because you have wider forms does not mean that you have more pressure. At the same height, both of these have the same pressure. Thanks for watching.
