Is it easier to blow mold with more water or less water?

Don't repeat questions and waste your wealth in the future.

Yes, your understanding is basically correct.

It is different from ordinary concrete when mixing, but the basic principle is the same. It is certain that it is easy to swell when there is more water. At present, concrete is generally pumped, and its fluidity is relatively large. Even if you mix it yourself, if you add more water, the material will be closer to the fluid, which will produce greater lateral pressure on the bottom of the side form. If the water-cement ratio is low, the pressure of flowing plastic state on the side formwork is relatively small. Your understanding is also in place, but more simply, you can directly understand the pressure problem in liquid state.

Of course, in practical engineering, it is a bit far-fetched to say that the mold will explode because there is too much water, because there is not much water, and it will explode if it is added too much, which shows that the problem of this mold is still big. Either this model doesn't work, or there is no good support. Moreover, the formwork design may have problems, and even the unreasonable design of the building structure will bring trouble to the formwork support. Some places are really hard to support.

If you want to know more, I recommend you to read Zhan Zhibin of Henan Second Construction Engineering Co., Ltd., and accidentally read an article about the prevention and control of concrete formwork expansion. You can check it online.
