Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-specialty grout.
It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials.
Several types of Portland cement are available with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available.

- Q: wet areas like dikes or dams.
- Yes. Type IV Portland cement is generally known for its low heat of hydration. This cement is used for very large concrete structures, such as dams, which have a low surface to volume ratio. This type of cement has not been made for many years, because Portland-pozzolan cements and ground granulated blast furnace slag addition offer a cheaper and more reliable alternative. These classes differ from the ASTM classes. I - Portland cement: Comprising Portland cement and up to 5% of minor additional constituents. II - Portland-composite cement: Portland cement and up to 35% of other single constituents. III - Blastfurnace cement: Portland cement and higher percentages of blastfurnace slag. IV - Pozzolanic cement: Portland cement and up to 55% of pozzolanic constituents. V - Composite cement: Portland cement, blastfurnace slag and pozzolana or fly ash. Read the links below for more details.
- Q: Who. and when invented cement?
- In 1824, English inventor, Joseph Aspdin invented Ready Mix Cement, which remains the dominant cement used in concrete production. Ancient Romans first developed concrete, which they used to build bridges, roads and buildings. Some of those early concrete structures remain, giving testament to the durability of the concrete and cement developed by the Romans. The Romans used lime and volcanic ash to create their cement.
- Q: My friend wants to know.
- Stick your feet in some wet cement. Then have someone drill into the cement, freeing two large blocks. Now you have your very own pair of custom cement boots! Just don't go near any ledges or large pools of water.
- Q: How does the cement produce! What matter! Why did she get angry?
- Fever is due to hydration heat phenomena (hydration, hydrolysis and crystallization and a series of effects)
- Q: They just put it on me, it worked just fine, then it came off on command without a trace (back in the 80's.) But I'm wondering what it chemically actually is.
- It's called, simply enough, dental cement, but chemically, it's usually zinc phosphate. Sometimes the zinc phosphate is mixed with polyacrylic acid, creating polycarboxylate cement. and in response to the additional detail: I don't know how the zinc phosphate cement is removed, but for the carboxylate, they use organic acids (especially citric, I think).
- Q: I am just curious, if I were to use 6 inches of reinforced concrete, making a 'domed tunnel' 100 feet long, how much weight would it be able to support on top? I know a dome can take a lot of weight, but what would be the math formula for figuring this out?Reinforcement would be 5/8quot; steel re-bar creating a skeletal structure to inject cement into and around.
- To get the math done for this you would need the math and or engineering sections. They would also need the psi rating of the concrete and the diameter of the tunnel. Chances are six inches would only be thick enough for a small tunnel.
- Q: I'm doing a project wich required me to calculate the transfer rate of Barite Cement from tanks to tanks. I've run couple of calculation but i'm not sure it is the correct one or not. Please advise.
- Cement is normally a dry powder if the system is a screw the rpm x the screw pitch volume will get you there. If you used a forced eductor use the ACFM x percent of flow /air per cent If you used a vac system and had head and lift and pipe loss and lots of other losses. Just add up all that and get a feasible answer..when you ask get specific... From the E
- Q: I have two uses:1. rock climbing shoes - (a) some early signs of de-lamination of toe sole from the rand; (b) side rand starting to have wear/scraped off2. trekking shoes (Teva with 'Spider Rubber')- front part of sole separated halfway. would like to maintain its waterproof properties, so having it sewn is not an optionwhich would provide better adhesiveness? Both rubbers are relatively soft sticky since these are special grip shoes. No shoe repair shop in my country has materials skills to fix rock climbing shoes. And normal contact cement won't hold the fix for the shoes' use. *I think 5.10 had a repair kit before using Barge Cement (yellow tube, instead of the blue one), but the reviews say that it didn't quite work.any other glue brands / tips? thanks!
- Applied some to a loose sole on a pair of shoes. It is also sold as Sportmans Goop Plumbers goop, household goop and a few other names, all very good and similar to shoe goo. I even used a small amount on my wife's earring, that the opal, tear drop glass fell off, and it is still holding after about ten years. I always have a fresh tube around because of it's flexibility.
- Q: Is there a law about the distance between the cement plant and the residential area?
- The provisions are necessary, pollution and noise is provided by the specific how far you can search that I do not know
- Q: What three substances are mixed with cement to make concrete?
- Sand, gravel and water.
