Using Explosives to clean out a concrete truck
Ғылым және технология
Myth Busters said It couldn't be done! Removing a load of set concrete from a concrete truck agitator bowl is a very difficult and time consuming exercise. The traditional method involves working from the inside with a jack hammer and painstakingly chipping it out. In this case we had a small diameter skid mounted mixer and the very limited space inside meant that a full size jackhammer just would not fit, the only option was a small hand held air pick. To compound the issue it was a special mix of very hard concrete with very tough fibre aggregate. Luckily, the guys who took on this job knew exactly who to call for a fast and cost effective solution using explosives, Demolition Dave was able to get the job off to a good start with a conservative but effective blast that lessened a considerable amount of material, opening up significantly more room to move and work inside, without any damage to the machine.

@D J i get to play with the other white stuff, concrete. I usually wore my safety specs but respirators never seemed to be around when you needed them. They are also horrible to wear when its 100 out. You can see the dirt marks on your skin from the moisture and sweat from wearing the mask. Few years ago OSHA started pushing for silica safety. It's a pain in the ass. i suppose it is safer but really, what isn't bad for you and what isn't known to the state of California to give you cancer.

Thank you so much for this Dave. Ever since the Mythbusters episode, I've always wondered if a skilled explosives expert could have broken up the concrete without damaging the vessel rather than just filling it with anfo and completely obliterating everything. I expect it would have been even easier in their case as it probably wasn't nearly as high strength nor fibre reinforced.

Retired Boilermaker, they used to have us go in the boiler with a 10 gauge shotgun. We used it to shot the clinkers out between the tubes in the superheat section. The trash burner in Newark NJ used ammfoe and broom handles to blast the clinkers out using the concussion, the whole boiler would shake and move.

I recognised the fibres having co-operated a concrete batching plant. We used to sell concrete with the fibres, but the customer needed to provide their own wash-out. The issue with washing-out at the plant is the water recycling system. The fibres clog the pumps used to move the water back into the batching system after washout. It wouldn't surprise me if washout was refused to the operators of this barrel.

FYI, there are clays that, when mixed with water and poured into holes, will expand to hundreds of times their mass and break rock and concrete up. It takes a day or so but its probably cheaper than the explosives. And most of the time you don't even need to be there, so no wasted man-hours.

I think they don't bother trying to get the concrete out anymore, they just eventually cut the mixer up for scrap steel.

It happened to me once. Basically, this can happen if something happens while en route to deliver ready-mix concrete. A breakdown, caught in traffic, etc. Broken axles are a common incident for concrete mixers maneuvering through new construction then the truck gets stuck with no place to unload. You only got about 3 hours or so, depending on the mix and temperature. My story is I was driving a loaded 8 yard (16 tons) mixer and the driver side frame rail broke while I was driving, the drum was leaning heavily to the passenger side. The first thing the mechanic said to me was "How'd you keep this thing upright?" I dunno, I just held on for dear life. Meanwhile the truck sat for too long while the mechanics put a massive weld on the frame to get it back to the shop. That truck sat in the back of the yard for years with the cured concrete still in it.
Man that is awesome.... not sure if you can but have you thought about doing it with the material in the air so when you blow out the debris falls away from what’s stock....
Hi Dave mate☺ you might say that was concrete evidence of somebody cocking it up, lol, I didn't envy you being in there drilling all them holes, but job done mate , and they still had a mixer at the end of it, thanks for another great video, stay safe, best wishe's to you and your's, Stuart.uk.

Thanks for tuning in again Stuart. Concrete evidence, sure is.
I would have shouted into the mixer, "FIRE IN THE HOLE!"
Wow, 100mpa and fibres!! Be interesting to know what that was being used for, 👍🇬🇧👍

What is is used for? ASCE concrete canoe competitions. Concrete countertops..sometimes done upside down with the surface poured first using a fine aggregate surface, then the fiber reinforced main layer. Expensive as frig for anything else.

Most of the regular clean out is just removing build up because over time it gets thicker and the capacity reduces, this is a whole different level of disaster when a full load goes off inside.

Grandfather was a mason. He knew of a guy who let the concrete set in a mixer like that. The boss made the guy bust it out with a sledge and a chisel

You are a brave man, Dave. I would have had the yellow gas bottle visible in the last shot removed (welding gas/acetylene?). Acetylene is really unstable, and a nice shockwave could have set the bottle off, removed the wall and put the mixer in low earth orbit... Glad it worked out for you!

Back in early 1990s I worked in a limestone quarry. Another part of the company was a lime plant. The lime kiln was,I'm guessing,200 ' long about 15' in diameter. To clean the slag out of the kiln,the company had a 10ga. Shotgun on a tripod and some workers stood there all day, maybe several shifts and fired 10 ga. Slugs at the paddles inside the kiln. I've seen 80 lb lime bags,dozens of them,full of spent paper 10ga. Shotshells.
