A question was asked earlier, why use a water reducer, why not use less water? The answer is that the water reducer is a surfactant (soap) which reduces the surface tension of water. It in effect makes water wetter so less water can be used. The water reducer also assists with unmolding, especially for the packerhead pipe by preventing the concrete from sticking to the steel molds.
Different mixtures of concrete require different cement/water ratios. The water reducer is a chemical ad-mixture that allows the concrete to exhibit behaviors that are suitable for work (such as drying time, 28 day compressive strength, early strength, etc.) without the needed cement to water ratio.
Yeah, but how do I make one just as good out of bagged cement mix, chicken wire, and dirt out of my yard? I think I'm not supposed to use water if I understand the video correctly. What about diet soda? Can I substitute spackle for cement mix? Can freshly popped popcorn be used as coarse aggregate? I'm a do-it-yourself kind of guy if you haven't figured it out already.
Another way of making these concrete pipes is welding rolled pipe and spraying the inside and outside with concrete, that way you can make a lot of different configurations of pipe like T-Joint Pipes or Y joint pipes. Although the process is a little slower than this, the pipes are much stronger and can be used for high pressure liquid delivery.
it is indian invention.am i right..because what ever world do invention...but indian always saying British stolan from india American stolan from india....English bolnay say aqal nahi atti.
"Steamhoses transform the curing warehouse into a sauna, the temperature rises to sixty degrees Celsius." I don't want to piss in your pocket, but in Finland, a sauna is at least 90 degrees Celsius...
So 100 years from now (or thereabouts) the entire sewer system will need to be replaced or it will collapse. I'd hate to be on the national sewer/septic board come 2116.
Amy Soderstrom that 100yrs is upon us and will hopefully start benefitting our industry again. The majority of concrete pipe was installed during the construction of America's highway system shortly after WW2.
What they do now is line the sewer pipes with a specual rubber membrane material. The material is actually stronger than the concrete itself and more flexible.
Jat Tan It's a surfactant. A chemical that breaks down water to make it spread out. Try putting a drop of water on a flat surface and it stays in a bead,than take a tooth pick dip it in liquid soap, now touch the bead of water and see what happens, thats what the water reducer does. It lets the water spread out wetting everything easier, with less water,making stronger concrete.
i might be wrong about this but it doesn't have pressure on all sides... right? since the earth covering it is pushing it downwards only, the force should be the gravity*mass of the earth on top of it, the side wouldn't do anything since there isn't any acceleration and the pressure is force/area, the only area getting the force is the top half of the pipe only way for the pipe to have pressure on ALL SIDES is if the pipe was sealed, and has pressure gradient different in the inside and outside of the pipe someone correct me on this, i'm not a physics major or anything
what i mean is the pressure pushing down will push the sides out but in the test there is nothing to resist the force pushing out. that's what i think anyway.
+YIC There is a top load, of course. There is also an equal load at the bottom of the pipe pushing up. The side loads of the pipe are outward as the pipe is being compressed from above and below.
On a serious note, many sewage and water pipes are way past the date they should have been exchanged. As time passes, minerals and other material accumulates on the inner surface of the pipe, and over time starts to make the pipe less and less spacious. I've seen some opened up old pipes with ridiculous amounts of accumulation. So much that the water was only flowing through an opening that was about a finger's width. It's a problem people easily ignore, since you really don't notice much until you're literally in deep shit.
kiln bricks suck! they are old as time and there are alternative old as time and there are new innovations kiln bricks have ruined the environment enough they are wrong bricks are not much energy efficient and are most importantly bad for environment they use a ton of energy to make it (2000 degrees fahrenheit) witch produces allot of co'2 i live in a brick house and spend time in allot of brick buildings and the walls do not hold much heat or coolness when its hot i must constantly use the air condition against cold its better insulated their are so many greener alternative brick for kiln bricks some are even better than kiln bricks (some hold and cooling better and do not need additional layers and will actually give out heat or cooling of the walls when needed) kiln bricks is much worse for the environment than incandescent light bulbs ITS ABOUT TIME THE USA OUTLAWS THE USE OF KILN BRICK AND PURE CONCRETE BRICKS a few examples of alternatives are timbercrete, papercrete , compressed earthblocks(ceb's), hempcrete, adobe, etc. they don''t use heating in the curing process and are better environmentally and some have even better qualities as a building block so go ahead and write letters to your senator representative make petitions and send them too finally stop the use of kiln briks BAN KILN BRICKS STOP THE USE OF CONCRETE AND KILN BRICKS
Fuzzcopter I like tigers I totally agree... but but but...I am not talking about those animals who want to enslave everyone to the environment. ...my ideology is to free everyone from the grid and of world homogenization and of the need of government. ..the more your home provides for you the less you need from the infostructre and government the less you need the less power they have over you...I live in the griddy system but my dream is an earthship permiculture type living ...when you look at a satellite map a city looks like an electronic motherboard ......I am a nature being and hope to live in harmony with nature soon ......and I will have every amenity I have now
Fuzzcopter I like tigers obama ,bill nye, and al gore are the environmental villians but there are environmental heroes. ..for me micheal rynolds is a very big environmental hero and deserves real respect the homes he builds are solid ,can be easily thought and poor people can build it themselves

Is nobody going to mention the fact that the truck driver in the beginning has the precision of a judo master?
What do you mean by that?
What they don't show you is the workers writing their names in the wet concrete before it's cured
Thanks for uploading these Kinds of Videos, It is Very Informative.
Thank you for these videos.
The fun just never ends.
Lmao you’re funny.
Powerful electric vibrators filling the cavity LOL
Our plant is way more high tech. And it's not an inside form. It's called the core.

Excellent video.....its very usefull.
Those pipes sick
How it's made RCP. Very informative video.
Sir very informative for engineers
this show is VEERRY addictive
The best technology in the words
"water, and a chemical that acts as a water reducer." Just add less water! =P (I kid I kid)
I start a job tomorrow morning making these. Wish me luck!
Good luck
well, how's the job billy?
Yeah, but how do I make one just as good out of bagged cement mix, chicken wire, and dirt out of my yard?
I think I'm not supposed to use water if I understand the video correctly. What about diet soda?
Can I substitute spackle for cement mix?
Can freshly popped popcorn be used as coarse aggregate?
I'm a do-it-yourself kind of guy if you haven't figured it out already.
Lol bagged concrete will work, just don't expect it to have a lot of structural strength.
Don't use popcorn. Use cockporn!
whoo engineering!!

Cris Wireless . We make those joints with these pipe after they have been cured over night. All the way from 12" i.d. to 120" i.d.
Very3x good information...
SO GOOD
Gilles smells funny :)
They use water and a water reducer? Why not just use less water?
Wait, the concrete mix has limestone and not slaked lime?
Very informative video. Excellent.
it is indian invention.am i right..because what ever world do invention...but indian always saying British stolan from india American stolan from india....English bolnay say aqal nahi atti.
Kamli Paul I can't bring myself to steal "stolan" ...
"Steamhoses transform the curing warehouse into a sauna, the temperature rises to sixty degrees Celsius." I don't want to piss in your pocket, but in Finland, a sauna is at least 90 degrees Celsius...
If this is a Canadian company, they should be reported to the Ministry of Industry for poor manufacturing processes.
i do this for a living precast but much bigger pipes usually
How big like 10 feet in diameter
varies from converter cones 60s to 72s to 84 to 126
Wendell Utt ok but how big in feet
its in inches so 6 ft 7 8 and 10 and a half
Wendell Utt WOW thanks for the information
Again at 4:20 the concrete is too dry.
if you listend to it from the begging its dry concrete the less water the better
i learnig about cocrete 2day,,, xD

Yet another factory I wouldn't want to somehow fall into. it's up there with timber and brick factories...
what's the water reducer?

Thanks bruh i appreciate the explanation

He never took you through it?
The announcer sounds like The Nanny
At 3:02 look at the bubbles. Not enough water.
This is old school pipe making.
CENTRIPETAL Projection Forming
Should have shown a Bi-Di packerhead, two pass machines are obsolete.
not at my suck ass plant, I am the MBK operator in complete hell hole
4:30 "temperatures raises to 60 C " Poor camera man....
My ex boss was a packer head.
I thought they were known as cheeseheads
Heavy shit.
Music doesn't help either.
nhatkiem -TAKE THAT BACK!!! Debbie does Dallas is the best instructional Video ever made!
I am cum struck! To think this could happen today! I will be writing my senator and ask for a PC5291Q
. Good video by the way.
4:39 That is not a good test. They need to bury it so it has pressure on all sides.
No. Thats not right at all.
i might be wrong about this but it doesn't have pressure on all sides... right? since the earth covering it is pushing it downwards only, the force should be the gravity*mass of the earth on top of it, the side wouldn't do anything since there isn't any acceleration
and the pressure is force/area, the only area getting the force is the top half of the pipe
only way for the pipe to have pressure on ALL SIDES is if the pipe was sealed, and has pressure gradient different in the inside and outside of the pipe
someone correct me on this, i'm not a physics major or anything
what i mean is the pressure pushing down will push the sides out but in the test there is nothing to resist the force pushing out. that's what i think anyway.
+Samuel Noall
The D-Load test is the industry standard for testing reinforced concrete pipe.
+YIC There is a top load, of course. There is also an equal load at the bottom of the pipe pushing up. The side loads of the pipe are outward as the pipe is being compressed from above and below.
I was expecting extruders would be involved
Fred Stiening
Lol.
What the hell is a "centimetre"?
they "bland" them together do they?
This is called the th- 'Bell section' Or bellend!
Music junked the video
i can never handle this woman's accent(?)
She sounds like a computer generated voice.
i want to see some 126 barrels made with cookies
lol
1 Year life span? Bullshit, the sewage lines we're using now is basically 200 years old.
1 HUNDRED years, smart-ass.

i hate the music in these videos
i want to poke it when its wet...

kiln bricks suck!
they are old as time and there are alternative old as time and there are new innovations kiln bricks have ruined the environment enough
they are wrong bricks are not much energy efficient and are most importantly bad for environment
they use a ton of energy to make it (2000 degrees fahrenheit) witch produces allot of co'2
i live in a brick house and spend time in allot of brick buildings and the walls do not hold much heat or coolness
when its hot i must constantly use the air condition against cold its better insulated
their are so many greener alternative brick for kiln bricks some are even better than kiln bricks (some hold and cooling better and do not need additional layers and will actually give out heat or cooling of the walls when needed)
kiln bricks is much worse for the environment than incandescent light bulbs
ITS ABOUT TIME THE USA OUTLAWS THE USE OF KILN BRICK AND PURE CONCRETE BRICKS
a few examples of alternatives are timbercrete, papercrete , compressed earthblocks(ceb's), hempcrete, adobe, etc.
they don''t use heating in the curing process and are better environmentally and some have even better qualities as a building block
so go ahead and write letters to your senator representative make petitions and send them too finally stop the use of kiln briks
BAN KILN BRICKS
STOP THE USE OF CONCRETE AND KILN BRICKS

Kiln bricks come in handy when you need to break a window. Any American will agree
