CLASH of the CONCRETES Dry Pour Concrete vs Wet Pour DEATHMATCH 

That is super interesting. Thank you!

"...mixing concrete with the minimum amount of water is the key." Yes; the key term there is "mixing." MIXING the concrete with the water. Not pouring water over dry, already-poured, concrete and letting the water drizzle down through it.

​@SomeDumUsrName but it's works

I glad you noticed.

Coming soon...stay tuned!

Probably because the dry pour was on the crack between the tables, and had more of shock absorber under it... this isn't a scientific test... it's known that more water makes concrete weaker. Would be interesting to make blocks and use a scientific compression test.

@@-Clandestine- It's more than this... concrete curing is a chemical process... if you have too wet of concrete it upsets the chemical bonds, not just causing the aggregate to fall. The chemical process that occurs in concrete is called cement hydration. When water is added to cement, a series of complex chemical reactions occur, leading to the formation of various compounds, including calcium silicate hydrates (C-S-H), calcium hydroxide (Ca(OH)2), and ettringite (Ca6Al2(SO4)3(OH)12·26H2O). C-S-H is the primary component responsible for the strength of concrete, as it is the main binder that holds the other components together. During hydration, the water molecules react with the cement particles, causing the particles to dissolve and releasing ions into the solution. These ions then react with each other and with the water molecules to form C-S-H gel. The amount of water added to the mixture, known as the water-to-cement ratio (w/c), plays a critical role in the hydration process. The ideal w/c ratio for concrete is typically between 0.4 and 0.6, depending on the specific application. When there is too much water in the mixture, the excess water fills the voids between the cement particles, preventing them from coming into contact with each other. This results in a lower concentration of cement particles available for the reaction, leading to weaker and less durable concrete. Excess water can also lead to the formation of calcium hydroxide (Ca(OH)2), which is a weaker and less durable compound than C-S-H. Calcium hydroxide forms when there is excess water in the mixture, and the water reacts with the cement particles to form calcium hydroxide instead of C-S-H. This can further weaken the concrete and make it more susceptible to damage. The chemical process that occurs in concrete is dependent on the water-to-cement ratio, and an excess of water can disrupt the formation of C-S-H, leading to weaker and less durable concrete. So it's important to have just the right amount of water for Portland type concrete to be as strong as possible. Not too much, not too little. After the chemical bonds are made then the water is less important because the concrete is no longer as chemically reactive. This chemistry happens as soon as the concrete gets wet, so there is a limited window for the mixing and curing.

@@-Clandestine- Anyone can say anything, they would need to provide some scientific evidence to convince me. If I need a little pad, I'm going to do dry pour due to the money saved and DIY friendly nature.

Doing the hammer test on a flexing table hahah

@MildarValsik Totally. Even if Paul got more scientific with conducting it. Lot's of variables. But it looks like either way is going to be good.

@@SanDiegoCaliforniaUSA I would say that for general usage it's going to be good. From all i seen so far I think I know the method I might use along with the dry pour.

Performance wise, they do NOT "seem equally strong." Wet pour was holding it's own on all 4 hits. The dry pour was coming apart all over the place during all 3 hits. The top of the dry pour was totally delaminating from the core during the hits like it was a separate layer altogether, and busting up around the edges. When the wet pour finally broke in half there was only a couple little straggler pieces. When the dry pour came apart on the final hit (3rd hit as opposed to 4,) it came apart all over the place. LOTS of pieces. 4 hits on wet pour broke it in half and the edges maintained their integrity. The dry pour was coming apart during all three hits - edges and all - and when it broke it just blew out all over the place. All in all, NO; these two pours are NOT equally strong and they do not "seem" equally strong.

I'm looking to do the same with a drive way going to be trying/testing different dry pour methods, to make a conclusion before I go full Dry pour driveway

Any of you ended up doing it.??

@@mr_4point681 I did🤙 I have a lot of videos posted on my RU-vid channel from my experience 🤙

It's a more solid subject.

No way! I haven't seen him upload much in the last 2 years.

I've been following along. We have been in contact.

He had to leave his apartment. I think the building is getting demoed for new building projects in Nassena.
