Cement mixtures should always be handled in a manner that eliminates prolonged exposure to the skin, and mucus membranes. Concrete and cement can cause serious burns and infections of the skin if not neutralized immediately. Cement residue will not simply rinse off the skin with water. the chemicals in the mixtures are still active and are absorbed into the skin. the burning chemicals can be easily neutralized by rinsing the affected areas of skin with vinegar. Only seasoned veteran cement finishers and laborers who work with concrete on a daily basis will have a bottle of vinegar always at hand.
The Romans used pozzolana cement from Pozzuoli, Italy near Mt. Vesuvius to build the Appian Way, Roman baths, the Coliseum and Pantheon in Rome, and the Pont du Gard aqueduct in south France. They used lime as a cementitious material. Pliny reported a mortar mixture of 1 part lime to 4 parts sand. Vitruvius reported a 2 parts pozzolana to 1 part lime. Concrete was originally developed by the ancient Romans, whose building techniques were lost with the fall of the empire and wasn’t reinvented until 1824 when an Englishman named Joseph Aspdin discovered Portland cement by burning finely ground chalk and clay in a kiln until the carbon dioxide was removed.
Dad was a builder of commercial and industrial buildings. When he had a job where the mixers could not get in, I got drafted to “operate” a wheel barrow. Seeing the whole process presented here in order, and with details, was extremely interesting. I will look at more of your presentations.
Thank you very much and i am glad you liked this content i will create another video about construction, cement, etc etc in my next creation stay tune for more like this
It's longevity is the best attribute . For highways , if formulated correctly , superior . Sections of U.S. 40 between Sacramento and Auburn Ca. were laid in 1929-30 and are in near perfect condition .

I love using cement in making an statue sculpturing because it doesn't fall off in many, many years, it stays together so long as the proper mixing & consistency are applied
I worked for 30 years in a foundry that made the wear parts for the machines that manufacture cement. There are a great many more details in this process that were not covered in this video but what was presented was fairly accurate. I suppose I am biased due to my occupational involvement but I think this video spent way more time discussing the simple process of mixing concrete than it did the very detailed and interesting process of mining, crushing, calcining, grinding and particle size and Blaine control of making the actual cement.
i was inside such oven changing a section with some guys,, i even had to be inside while it was turning, we walked to the end and look down in that big pit, somthing i will never forget..
They've stole "how it is made" and stuck a voice over on it. It's diabolical. It's taking something perfectly good. Trying to make it their own. And convincing themselves they've somehow achieved followers and likes for their own work. It's everywhere bro. Leaches
Cement (the Adhesive) manufacture needs lots of Heat to make. Yes, there is underwater Concrete, and concrete which can be poured/cured in freezing weather.. You can also add gravel, stones, & rebar etc. to concrete..
I am so passionate about the manufacturing of cement, how I wish I have what it takes to go into manufacturing cement, I will have love to own a cement producing company, pls I need a mentor on this roll.
My father told me how in his apprenticeship he learnt about different types of mortar, concrete and how these are made in ratios! I now find it interesting at age 50. He did his apprenticeship in Yugoslavia and then moved to Austria to work. He was a site foreman! Then my parents moved to Australia! Cheers ❤
Boy…… that took me back to my carpentry apprenticeship in 1973!!! We mixed all our own concrete in an on-site mixer…..which produced one barrow load of concrete!!! Into the mixer went a bucket of water, five shovels of aggregate, then two shovels of cement!!! We let it mix…. Then added more aggregate to stiffen the mix!!! We used this method for foundations, slabs and concrete walls!!! If pouring a foundation and the concrete stopped flowing….. the boss would ask for a pea soup mix, which was basically water and cement, to unblock the jamb concrete!!! 1500 degrees Celsius to make cement….. don’t think solar and wind power can generate that amount of heat!!!! Fossil fuels forever!!!! Regards Ian 👨🎤🇳🇿👍🍸🍸
HOW DO YOU MAKE CEMENT OR CONCRETE WATER PROOF LIKE S CELLAR I noticed when building a house next to a cannels when the high tide comes in, the cellar starts to get water in it making he cellar flood, what do you do to make the cement Water Proof?
I seem to remember we used to add washing up liquid to our water when mixing cement . It acted as a good plasticiser when plastering walls. I think an additive is now marketed instead.
The reason that washing up liquid is a really bad idea in cement products (usually mortar rather than concrete) is that it has a very high salt content, and this can lead to efflourescence in brickwork or other adjacent masonry. This appears as white deposits on the surface, and is very unsightly, and ultimately damaging to the masonry. The admixes used in place of detergents avoid this issue.
Concrete is the preferred material for city streets in some parts of the USA. In other places, even at similar latitudes, streets are paved with asphalt. What are the respective cost, utility, and longevity factors? I presume that asphalt is cheaper to apply or repair, but wears faster and does not survive many winters that require lots of salt to melt snow. Concrete may last forever, but it is cast in blocks that, over the years, tilt or buckle, making a ride rather bumpy, and whose replacement may be expensive. Am I naive or mistaken?
The thing I find most interesting is the weight of it. I used to deliver truckloads of bagged cement. It only takes about 12 pallets to get your gross weight up to 79,000 lbs.
Your vid show about concrete mixture or making, not about how 'cement is made'. I expect with the 'title' you present a comprehension method about how cement are actually created at the basic level in its factory! materials, elements, additives, compositioning, until lastly, packaging. So, it's little dissapointed!
I have worked with cement for large parts of my life. Everything from receiving and reselling from dealers, to building houses and have always wondered how cement is made. Thank you for a good review of the process. It was then that the cement bags weighed 50 kg and I weighed 63 kg and I was able to move 250 kg in one single lift. 🤣😂
Too often people forget the most important part of laying concrete, the curing. Keep it covered and wet for a week and it will be much harder and durable.
You can't just add water willy nilly. The strength of the concrete is carefully calculated. The amount of cement to water was part of this calculation and by adding extra water on site to make it more usable will weaken the concrete which could be critical.
At 3:37 a concrete truck pouring wet concrete and a palm hat worker from Vietnam. Word print in truck tank BE TONG PHUONG HOANG means Phoenix concrete.
Most impressiv is how old old this is. 2000 years ago, roman empire did make cement which was usefull under water. Hagia Sofia have survived many earthquackes and it repair itself. Old concrete is better than new one. That is very impressiv.
The slower the curing period, the better and that includes lots of moisture. If concrete sets too fast or false sets and shrinks it can be a really costly error. In a process, some slabs are immersed in liquid to cure very slowly. Cement is relatively impervious to water, so it takes a lot of water to saturate the cement and get the optimum strength from it. The clinkers can be stored outside and they resist water to the point that they are unaffected by it. It isn’t until they have been pulverized that they begin to accept water. Our current world would be vastly different without cement.
I'm surprised there is no mention of the angularity required of the aggregates. It is required the sand and stone have sharp angles. An on-site engineer can reject a batch if the aggregate is not angular enough. It is said we will soon face a shortage of workable sand. You look at the desert and think that is crazy but windblown sand is round and river sand is angular. We need the river sand. Great video. I was interested in the kiln process. "How did anyone ever figure out you had to cook the parts for the best results?", I ask myself. Granted chemists know how and why but someone figured it out before modern chemistry.
To make an attractive and less jarring finish leave the concrete to set (takes a few hours depending on temperature) then brush the surface gently while washing with plenty of water. It will expose the aggregate.
We have plenty of raw materials here in Candoni, Negros Occidental, but, we don't have investors for Cement Factory. All Nations really needs a Cement Factory.
Hasten or speed up. Fasten was the incorrect choice of word and application for the thought being conveyed. Or am I being too perspicacious for you to understand my position?

That is correct

Did the unsavory criminal elements in ancient Rome dump bodies as filler prior the pour too?
It's also doubtful modern cement/concrete will last as long a roman variety. The Romans were also able to pore their concrete underwater.

As simple as one may think of concrete, it is a very technical thing to understand.
the only thing simple about concrete is concreters
Excellent. Good informations which I didn't know before.

Maybe then we wouldn't have these bizarre mispronunciations. "A kiln is a long, _cyndrilical_ oven."
I agree. Meta Al that is
But anyway, we have some knowledge or understand something more. Focus on the positive.
I know right...
How did they do it back in the 1930's? We know this technology didn't exist back then.
How did the Roman Empire do it, they wouldn't have had the technology that we have today

It’s amazing how concrete can be finished in so many different ways. Smooth to rough to different colours to different textures
Hello, how are you? It's fascinating how with this cement you can build incredible things and beautiful buildings.

Cement and concrete are the foundations of most of the world. No pun intended.

It was a good presentation except you left out the chemical reaction that would explain how the water causes the cement to harden.
I seem to remember we used to add washing up liquid to our water when mixing cement . It acted as a good plasticiser when plastering walls. I think an additive is now marketed instead.
The reason that washing up liquid is a really bad idea in cement products (usually mortar rather than concrete) is that it has a very high salt content, and this can lead to efflourescence in brickwork or other adjacent masonry. This appears as white deposits on the surface, and is very unsightly, and ultimately damaging to the masonry. The admixes used in place of detergents avoid this issue.
Adding a small amount of sugar makes it that hard that you need an pneumatic hammer to break it.
No matter what you do , efflorescence occurs . Eventually it does disappear , but this does take a long time
