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.

Is nobody going to mention the fact that the truck driver in the beginning has the precision of a judo master?

Thanks for uploading these Kinds of Videos, It is Very Informative.

What they don't show you is the workers writing their names in the wet concrete before it's cured

Excellent video.....its very usefull.

The fun just never ends.

Thank you for these videos.

Sir very informative for engineers

Those pipes sick

How it's made RCP. Very informative video.

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.

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.

Powerful electric vibrators filling the cavity LOL

Wait, the concrete mix has limestone and not slaked lime?

this show is VEERRY addictive

Our plant is way more high tech. And it's not an inside form. It's called the core.

Very3x good information...

The best technology in the words

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.

I start a job tomorrow morning making these. Wish me luck!

They use water and a water reducer? Why not just use less water?

"water, and a chemical that acts as a water reducer." Just add less water! =P (I kid I kid)

Gilles smells funny :)

whoo engineering!!

SO GOOD

Very informative video. Excellent.

i learnig about cocrete 2day,,, xD

"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...

what's the water reducer?

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

if you listend to it from the begging its dry concrete the less water the better

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.

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

@workingforworldpeace He never took you through it?

The announcer sounds like The Nanny

Again at 4:20 the concrete is too dry.

This is old school pipe making.

At 3:02 look at the bubbles. Not enough water.

Should have shown a Bi-Di packerhead, two pass machines are obsolete.

CENTRIPETAL Projection Forming

Heavy shit.

4:30 "temperatures raises to 60 C " Poor camera man....

they "bland" them together do they?

My ex boss was a packer head.

What the hell is a "centimetre"?

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.

I was expecting extruders would be involved

This is called the th- 'Bell section' Or bellend!

4:39 That is not a good test. They need to bury it so it has pressure on all sides.

Music doesn't help either.

Music junked the video

i want to see some 126 barrels made with cookies lol

i can never handle this woman's accent(?)

i hate the music in these videos

1 Year life span? Bullshit, the sewage lines we're using now is basically 200 years old.

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
