For your next experiments with this demolition method, I'd be curious to see how a plug would perform if you sprayed water into the drill-hole before applying the grout. That way more moisture is preserved near the reaction to keep it going longer. Either way, very fascinating video! Keep up the great work!

[@AKuTepion]

@@shanejohns7901 Cody hypothesised that once the crack appeared, the solution dried up and stopped the reaction from continuing. He also said that the rock might have absorbed some of the water. So suggesting to moisture the rock first actually makes perfect sense.

[@shanejohns7901]

@@AKuTepion No, it doesn't make sense. The stuff is expanding because of the water, not because of the rock. If you wanted more water, you'd put more water into the mixture itself, not along the edge of the rock surface. Look at the OP's logic: ``That way more moisture is preserved near the reaction to keep it going longer.`` Preserved near the reaction? The reaction is between the water and the quick lime. It is not reacting with the rock.

[@nikolaisoerensen]

Well i think it makes sense, you could also saturate the rock with water, so it is less thirsty, but maybe also increase the amount of limemixture in general

[@shanejohns7901]

@@AKuTepion Again, you don't understand what is happening. The water is reacting with the quicklime not the rock. The rock splits because of the pressure in the hole caused by the EXPANSION of the quicklime once it's made wet. Cody also explained the 'fuse', so that it doesn't expand prior to being jammed into the hole of the rock. If you think more water would be helpful, then it should be added to the quicklime before being put into the rock hole. Given that some of the water CAN evaporate or absorb into the rock in the rather lengthy time this takes, more water may well be helpful. But again -- added to the quicklime, not to the rock.

That snowstorm is crazy. The leaves are still super green but yet a snowstorm is breaking branches off. Granted the leaves give more surface area for snow adding more weight but still a snowstorm that big this early on. The clip at the end reminded me of the time We had a HUGE ice storm in Tulsa in 2007. It was crazy the roads were mostly fine but the trees and powerlines were not. Being outside was wild. The sky was lighting up with greens and blues from powerlines and the sound of branches and trees falling constantly. But yet it was quiet because no one was driving and the power was out for lots of the city. I wish I had a camera back then to film it because it was truly a strange experience. I want to experience it again but not the 2 weeks without power.

[@Thalatash]

I was going to say that it looked more like the ice storms that we get in Ok. because of the branches breaking like that.

Cody, could the mortar be made into rods that can be dipped in water before pushing them into a wet rock?

Extremely safe to store inertly in a small dry space without risk of explosion.

[@Mike-bs5pi]

@@jerrydumas9848 yeah Ive been thinking about this and my initial thought was maybe using slushy straws buts waste and a few other factors deterred me from the idea and I just settled on a sort of hybrid idea based on tampons. A tubular object with a low coefficient of friction to form and store the sticks in, then when ready to use, fill the hole with water, let it set a bit, then add more water and with a ramrod action push the mortar out of the tube into the drilled hole and then cap the hole. I'm super interested in trying this out, but it will be at least a couple of months before I'm able to. That said, I've never handled this material before so I don't even know if it's possible to form it in a big straw, sturdy enough to be used in the suggested manner. Copper pipe might work if prepped well but I was thinking when the metal contracts more than the mortar as it cools, it might shrink bite into the mortar too hard to allow it to be released. I'm sure Theres a way. If Cody is inspired by the idea I'm sure he can come up with something better, so I'm looking forward to more in this series. If it is in fact a series.

I worked a lot in constructive deconstruction stuff .. like breaking down the top of concrete piles of various sizes for deep foundations to make place for the actual foundation to be build or building and similarily "top cutting" slurry walls and so on. When we didn't just go straight with jackhammers (as it is usual for concrete piles), we used something remotely similar. We drilled holes in to a slurry wall for example and then had a strong hydraulic pusher which essentially broke/exploded the concrete in nicely predictive cracks along the desired height.... And actually, this technology is _WAY_ older and in egypt for example, they used wheat and other grains which were put into similarily drilled holes ... _then watered_ afterwards and securely locked in to the hole to not just spill out as it expands due to the mouisture they absorbed. It just takes some more time .. but works still in the same way as your grout solition or modern concrete split machines. ;) Mkay .. it's _WAY_ less interesting and the chemistry is completely different.. but yeah .....

There's a british TV show (The Edwardian Farm I think) where they showed the traditional process of making lime in an original lime kiln, the amount of fuel they put into it it is immense to bake the rock into something that ends up being turned into the evil clay that can burn your skin off... :S

[@Hendlton]

I watched that. Didn't they have to keep watch of the kilns for days, because that's literally how long that amount of fuel would burn?

[@baitbuckets9844]

That was a good episode

[@easydoz1]

I think they still needed a bigger coal to limestone ratio....

[@nahco3994]

I guess that demonstration can go a long way to explain the frankly absurd amount of energy that is consumed by the global lime production. Now couple that with the fact that lime is one of the most basic foundations of our whole industrial complex (in some sense it's used almost everywhere... steel production, agriculture, cement production, etc.).

[@Hendlton]

@@nahco3994 Heh... "Basic"

[@finnleybourne1232]

Great video, I love the demonstrations you show comparing two different methods side by side

[@mezzmainia]

One way you could take this idea is to effectively make a stick out of the quick lime with a thin water pipe running up its centre. Once the stick is in place and sealed into it's hole, you can inject water into the stick using the pipe. This way you don't need to worry so much about the fuse since you chose when to pump the water, and you're working with a solid stick you can place into any hole rather than a liquid or paste you'd need to pour/press into a hole. The stick could be made by taking the powdered quick lime and pressing it into a mould around the pipe, it seemed to hold the shape of the crucible rather well when tipped out so it doesn't seem like much of a stretch to think this could work.

I love when Cody uses chemistry to engineer solutions to problems

[@incognitotorpedo42]

These contractors were building a house in my neighborhood, and discovered a very large boulder in the way. They had a crew of three jackhammers working 8 hours a day for THREE WEEKS. If they had used expanding goop, they probably could have taken care of it in a few days with no noise. It was years ago, and we still call the place "the jackhammer house".

[@Skorpychan]

Quicklime reacting so aggressively with water certainly explains why official instructions for a cow that dies of anthrax is to throw it in a deep hole and bury it in quicklime.

[@joshd2013]

Same as one that dies of blackleg here in Australia

[@aodigital9421]

Very interesting story, elf.

[@nyanpasu64]

>Previously, lime (calcium oxide) was recommended by the Canadian Food Inspection Agency (CFIA) as an anthrax disinfectant. However, a recent scientific review of the subject has found evidence to suggest that exposure of anthrax spores to calcium may aid in their survival and viability. For this reason, the CFIA no longer recommends the use of lime for agricultural anthrax disinfection.

[@Skorpychan]

@@nyanpasu64 The UK government advice was such in the 1960s when said cow actualy died. There was also a restriction on growing anything on the land, so it's a car park now.

[@pauljs75]

@@nyanpasu64 It was probably the boiling temperature if the reaction was large enough. (It's exothermic.) But maybe there was something lost in describing the process, so those expecting the same result while minimizing materials didn't produce the heating effect that killed the germs.

*@Cody'sLab* 21:20 Maybe it would be cool with a contact microphone onto the rock, that can pick up all the small sounds the rock makes when it starts splitting? :)

[@libertyauto]

Thank you Cody. I love it when you trick me into learning something new.

[@nonofyabeeswax9955]

As a idea, could you mix it with a powder that releases water when heated (something like coppersulfide)? Of cause that would only work if it doesn't react immediately. But otherwise, as long as the released energy is high enough to release further water, you would only need to "ignite" the mixture to start the reaction.

[@WatchingCrow]

Rewatching cause I think this is just too cool! Can’t wait to see more from this idea!

Ask Jeff Williams did a video on using expanding grout as a secondary method of rock breaking in his underground mine. Good option for places you don't wanna risk blasting.

We use stuff like this for rocks that are too big to move at our claim, works great. I also suggest looking into a micro blaster. It uses .22 caliber sized charges, way easier and safer than dynamite.

I recall watching a guy who does this professionally and admittedly, their mixture takes a decent while to split the rocks, so I'm assuming there's something to be said for having more sodium carbonate in the mix.

[@papanyanz]

Two questions : What if you add some gelling agent which could potentially prevent the moisture to be absorbed qiuckly into rock ? Also what if you use soduim sulfate instead of carbonate - it will form gypsum in situ, any benefits?

[@moonasha]

It seems like this would be most useful if you made a grid of holes in a rock formation, and did this in them all at once to cause maximum deformation. Or shaping the drilled hole formation in line with the weaknesses in the rock formation

[@gizzymoee]

Curious here, if it's taking hours maybe days for the reaction to happen how do you know when the reaction is truly finished especially in a mining environment where you can't see anything but the top surface? Is there a potential of rockfall because of an ongoing reaction you thought had ceased and not made much impact but truly it wasn't finished or it weakened the face of the rock to the point of eventual fall/collapse. Whereas a big boom you know is over by counting the booms and if you placed 6 and 6 go off great if you place 6 and 5 go off oh bad news. Again just curious I'm not hating no scientific background, just curious.

[@hayuseen6683]

I'd assume you limit the scope and break away managable chunks, and if it fails then you take a pick to it until it breaks away. Or rinse the goop out.

[@skeetsmcgrew3282]

@@hayuseen6683 while yes, you can count booms, you are also more likely to create unseen structural cracks, depending on the type of stone. So its a similar amount of risk. But youd definitely be less likely to get sloppy with explosives

[@Madnessnunky]

If you had a prepared product from a company, it'd likely come with a datasheet detailing reaction durations in various conditions. You'd know full well when it was no longer functioning based on the amounts you used. While still leaving the potential for unforeseen fractures, you'd at least be certain it's not growing any further past your deadline.

[@sid6645]

Well you have the fuse, and since its a chemical fuse it is a 100% reliable unless the reaction mixture was messed up from the start. Which is a concern for "conventional" explosives as well, so I don't see it being an issue once cody gets proper numbers on how the sodium carbonate effects reaction speed.

You should try loading this stuff into a balloon... That might solve the "rock sucks up all the water" and "cracks formed so air could get to it" problems. If your standard dollar store balloons don't stand up to the expansion, I remember playing with some really heavy duty ones called "punch balloons" when I was a kid. Those suckers were thick.

Cody mining with cooked limestone. Cody: "I used the stones to destroy the stones"

[@yiannik6000]

I wonder how this mixture might fare up inside a plastic bag. You could mix a large batch, pour into individual sealable bags, and place into multiple pre drilled holes in a rock face. The bag could also help with moisture, incase a crack forms it wouldn't dry out, and the rock itself can't absorb the moisture. And this is how I will shake up the mining industry worldwide. Thank you for coming to my Ted talk.

[@DrummertheCody]

I’m looking forward to the full scale demo out at chicken hole! Could you pump this stuff into natural cracks in the rock to similar effect?

[@Direblade11]

I'm thinking a bore hole would be the most efficient way to limit area that it needs to expand to

[@ogreunderbridge5204]

Statly regulations can be a drag, I feel for you Cody. It was fun seeing your exposives adventures on the farm. But then, obstacles gives new challenges to solve using the ol noggin. For simplistic practical rock use, have you considered the good old pre Nitro Glycerin mining way of hardrocks, of wetting stone and expose to intense heat ? A torch with propane and compressed air ought facilitate putting it inside narrow drill holes. A bonfire starts and makes a tunnel. A conduit to bottom of tunnel coupled to an outside placed woodstove with suitable lenght of chimney provides fresh supply of air by sucking out the old inside.
