I used to work at a cement factory. The video is factual correct without getting into too many details. Modern grey cement production uses a tower with a calcinator and a cyclone - the cyclone removes a lot of water very quickly. You need less heat to remove the water. The production is sped up multiple times making it far more energy efficient than the rotary kiln. Cement production uses a lot of waste products like the ash mentioned. Waste has become a ressource - you pay for.... Cement production releases a lot of CO2 - however a lot gets trapped again in the process of curing (when the cement hardens).
Very good brief explanation accept one. The finishing process is performed at the time the concrete is curing and not after. Usually 3 to 4 hours after being poured, skreed, floated and or fresno smoothed, a trowel, broom or stamp finish is applied. The only finish performed after curing is acid etching, grinding and polishing. 70% strength it usually obtained after 7 days. 90% after 28 days. Concrete can cure for up to 90 years. The Hoover Dam project was still creating heat from curing years after completion.
I don't even remotely believe that whole Hoover Dam claim. It sounds like another asinine claim to wow and dumbfound the masses.🙄 Are we to believe that they imbeded wireless Tempurature sensors throught the concrete? Concrete Dams are poured in blocks, using a quick curing cement, and each block is essentially cured by the time another block is poured on top of each block. Are we to believe that the Hoover Dam is the one concrete structure in the world that somehow created an anonymous forever lasting chemical reaction that defies Physics?

The part where he started talking about the clinker and the clinker cooler (02:10). It reminded me of that one Rick and Morty episode with the Plumbus. 😅😂😂😂😂
I run a concrete plant. There are a few batches (recipes) we use all the time for things like driveways, sidewalks, foundations etc but for special projects (large commercial jobs etc) there are hundreds to choose from and my company has experts that can whip up a new one whenever needed. There's also a lot more than just retarder. There's water reducer which also increases the strength of the concrete, fiber (steel, plastic and glass varieties), and we can even change the color of the concrete.
Retired R/M driver here. Did a good job explaining about cement. The ancient Egyptians had their own version said to contain lava ash. I know this vid was about cement but maybe you could do a series focusing more on concrete.🙏💓
It was the Romans, not the Egyptians. Volcanic ash, called pozzolana, or pozzolan, was mixed with slaked lime, and that mix was mixed with sand and gravel to make Roman concrete. It lasts for thousands of years.
@@robinpage2730 I heard it also had tiny chunks of sea shell embedded in it. Seems the shell was a reservoir of calcium carbonate that seeped into the surrounding cement material over eons and sustained its structure. When we made it, it was all ground very fine for strength and fast set. The Roman stuff lasted, well it still lasts…
@@robinpage2730 Pozzolana is not just a form of volcanic ash but as a sandy form of volcanic ash made out of micro-particles of micro-porous silica almost like diatomaceous earth to allow 10,000 times more surface area to react with the burnt quicklime or slaked lime to form a NON-POROUS calcium silicate which is also very strong. Since the late 1960s many scientists and engineers has been trying to find ways to improve on this principle of calcium carbonate to silica inter-reactions. In the Eastern Roman Empire they have no pozzolana or pozzolana sandy volcanic porous ash but they instead used a substitute called crushed and powderized bricks which has been crushed and grinded until it is as fine as white flour. How long it will last? One archeologist demonstrated how that product is made by mixing an equal volume of burnt quicklime and powderized brick powder and adding sufficient water to form a mortar and slap on on a rock wall wet with sea water to make it water proof and he said "IT IS GOOD FOR THE NEXT 5,000 YEARS!" Others use either silica sand with a silica content of 95%, or silica brick with a silica content of 97% or, quartz-quartzite-diatomaceous earth with a silica content of more than 97% up to more than 99%. They are all crushed, pulverized, grinded, powderized to become as fine as bleached white wheat flour so that they will dissolve in water (water is a universal solvent) and when mixed with water soluble burnt quicklime or slaked lime they form calcium silicate cement. One scientist-engineer went so far by mixing an equal volume of sodium silicate (waterglass with a 50% silica content and 50% sodium carbonate content) mixed and dissolved in hot water and allowed to cool into a viscous liquid similar to honey and then mixed with an equal volume of burnt quicklime or slaked lime until both has completely dissolved together (plus some additional water so that he can add a calculate volume of sand and-or graded gravel which are both mica free so that the resulting cement mortar and-or concrete is very strong) that he ended up with a weird form of almost glassy or glazed form of calcium silicate mortar and-or concrete which is very strong and virtually non-porous!
Modern Portland Cement is simply synthetic volcanic ash. You can use any kind of silicate, it's the temperature, heating and cooling times that determine the quality of the final product.
I do construction work and I never actually knew what cement was made of. It can be a lot of physical labor though especially when doing larger pours, or working with drier concrete. I’ll bet working in the rock quarry blowing up rocks and operating large machinery would be super fun though
Worked at a cement plant for a few!! Raw meal is cooked to become clinker, then mixed with gypsum to make cement!! Mix cement with rocks (aggregate) becomes concrete....
If i have limestone and clay could it possible to makes cement at home.? I know that buying much cheaper than making, but i have the problems with transportation.
I had a customer who was a cement factory in Nevada. They had a sign up that said "Number of days since last fatality", along with pictures of men who had died working there. That long kiln and what comes out at the end is dangerous.
Years ago I worked at the only admixture and crete curing compound plant in the U.S. Now this plant is gone , and many others have popped up I realize how important my job was.

Cement has a life of 100 years where as ancient Romans Indians and Egyptians used only limestone as binding material for their construction. Their constructions are still standing even after 1000's of years. Are we are missing something here, definitely, like the video said cement industry is worth more that $600 billion and limestone is freely available just need to dig and transport.
They added pozzolan (volcanic ash, which makes the lime putty/aggregate mix smoother and easier to work) and eventually realized that it actually reacted chemically with the lime to make a hydraulic cement. The secret is the silicates and aluminates in the ash. Clay also contains these compounds, that's why it's a raw ingredient in Portland cement. The difference is, we burn it much hotter than they did. The clinker we depend on for fast setting times, was garbage to the Romans. The chemistry is not good for durability.
Perhaps modern concrete can carry much greater loads than way back then, but not many people need it to do that, so why can’t we just get an option to buy the same stuff the Romans put out ?
The main difference between roman concrete and modern is the larger chunks of quicklime they mixed in, this made the concrete "self healing" and therefore can last longer. Today you can buy concrete that has a similar composition as roman concrete but better in every way, the only problem is that it is waaay more expensive... and most chooses to not sell it. In fact most buildings today are calculated to last just 50-100 years and therefore expensive concrete is not needed. If you want to see the best concrete we can create today look att the concrete in nuclear waste storage bunkers, that concrete often uses iron ore as aggregate and is calculated to last 1000+ years :)
Fly ash is in fact coal ash... produced by coal power plants. What are we going to substitute for it if we shut down all the coal plants? I can tell you, fly ash is almost as strong as concrete all by itself when prepared properly. I used to work construction and had to try to demo it. That sucked. Concrete will be much weaker without it. What are we going to build with?
i think concrete isn't in tensile strength but more of it's compressive strength (crushing force) that's why we have different strengths in mpa or psi. tensile strength refers to reinforcement bars (pulling force)
First, you take the dinglepop, and you smooth it out with a bunch of schleem. The schleem is then repurposed for later batches. Then you take the dinglebop and push it through the grumbo, where the fleeb is rubbed against it. It's important that the fleeb is rubbed, because the fleeb has all of the fleeb juice. Then a Shlami shows up and he rubs it, and spits on it. Then you cut the fleeb. There's several hizzards in the way. The blaffs rub against the chumbles, and the plubus and grumbo are shaved away. That leaves you with a regular old plumbus!
Cheer~~~a powdery substance made with calcined lime and clay. It is mixed with water to form mortar or mixed with sand, gravel, and water to make concrete.😊

I haul dry cement from time to time and it’s nasty stuff it’s so fine it gets everywhere and at the end of the day you gotta blow it all out of your nose
Wear a good quality face mask. The dust will kill you faster than smoking. I am 70 years old, and retired. I occasionally worked around carbon black refineries. I wore a full quality face mask and used petroleum jelly around my ears. I still had to blow my nose to get rid of some carbon black. I never never got in my vehicle before a good shower. Carbon black is just like coal, causing black lung cancer.
But how did they every figure out that this is even possible? Who discovered that if you take that particular type of rock, crush it, heat it, crush it etc it becomes cement. People in the past were so smart. What we do today is developing. In the past they really invented stuff.
Lime mortar had been used for thousands of years, but takes weeks to cure. The Romans sometimes experimented with additives to modify the workability of the liquid mix. They added pozzolan (volcanic ash, which makes the mix very smoothly workable) and discovered that it actually reacted with the lime to make a hydraulic cement.
Once humans had fire, I think all it took was for someone to put a limestone rock or maybe some sea shells in the fire (calcium). When it gets hot enough, the rock breaks down to a powder. When that powder gets wet again it will solidify. This is basic lime. Cement is a relatively new variation that adds sand (silica) to change the hardness of the finished product.
@@steveburian6880 Yeah so cement is actually also a development instead of an invention 🤔 But it's true, I think a lot of stuff has just been stumbled upon.
