PORTLAND CEMENT
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.
- Thomas hit the second part of the question, but not the first part. For a VERY simple comparison: Portland Cement (PC) is a complex mixture of anhydrous calcium, silica, lime, etc. that hydrates (not dries) with water to form CSH (calcium-silicate-hydrates), the basic crystalline structure of cement/concrete. Pozzolans are not PC, but are simply forms of amorphous silica which can react with the byproducts of the hydration of PC to form more CSH. Typical pozzolans are fly ash, ground-granulated-blast-furnace slag (GGBFS), silica fume, etc. They do not begin reaction (or contribution to the hydrated cement crystalline structure) until later in the process... from about 7 to 14 days of hydration. Therefore, while a concrete mixture heavy in proportion of pozzolans will usually have a finer crystalline structure and higher 28 or 56 day strength, it usually lags in early strength gain up to 7 days and will exhibit a lower heat of hydration due to lower PC content.
- Q: Hi , I would like to know what type of temporary crown cement would burn the quot;lowerquot; tongue when in contact with ?I went to a dentist to do a dental crowning and the doctor use a type of cement that has burning sensation to my tongue . When I flip over my tongue I saw a painful red spot below my tongue.
- Many temporary cements contain eugenol (clove oil) - which gives a tingling or slight burning sensation when in contact with skin. I have never seen it cause a burn mark though The most popular brand in the UK is Temp Bond
- Q: why is cement used for ? binding aggregate and sand or is used for increasing tensile strength?
- interesting i dont know
- Q: Was the gulf oil leak sealed with cement as stated, or was it concrete?
- In the oil industry it is known as cement. Granted, there are non-cement constituents, but there is no aggregate as the concrete that we're most familiar with has. The cement has to flow through small gaps and can't have rock chunks in it. The cement used in the oilfield also has a number of other additives to control such things as setting time and flow characteristics (called rheology).
- Q: my son got some new posters and wants to hang them up. he has a very light blue (almost white) color painted on his walls (with panelling behind it) and i wanted to know if i could use rubber cement to hang them, or if it would damage the paint color after removal?
- There are actually packages of little sticky balls (grey, consistency of gum) that you can use. The schools all use it to put posters up on their walls. It's the same stuff that comes with the glow-in-the-dark stars and planets that some kids put on their ceilings...
- Q: How many 50kg of cement could be used for a 1 cubic concrete casting?
- Making a bunch of assumptions (follow Tigri's good answer) 1 cubic meter of concrete/cement weighs about 2400 kg so you would need 48 bags/units of 50kg each.
- Q: how many bags of cement will i have to buy if i wanted to fill a 5 gallon bucket?i am going to fill it half full, put a friend of mines' Christmas present into it, and then cover the rest.I worked in concrete for two years so i know how to set it all up, but we generally dealt with trucks of concrete, not buckets.so. how many bags? or how many pounds?
- Hard to say. Just one 12' long 2x4 in a 5 gal bucket of cement should be rock steady, but hang a banner big enough to catch the wind between the tops of two like that and the whole thing could tip over fairly easily depending on the wind and the size of the banner.
- Q: What is Oilfield cement, is it the same as the cement that cars drive on?
- I have never worked in the Oil Patch, but I believe oilfield cement is a mixture of sand, aggregate and a barium compound (barium carbonate, maybe). If you look at the Periodic Table, you will see that barium lies under calcium, and has the same properties (more or less). Since barium is denser, when an over-pressured oil reservoir is breached, this mixture plugs up the drill hole until the well can be capped. This is a major use of the element barium.
- Q: Need to remove cement like glue from painted metal. Any house hold items i can use or do i have to buy a glue remover. i.e. rubbing alcohol , cleaners ect. Thanks
- Go to your local paint store and get a solvent based thinner, apply to area and wipe off. Should work but if cement based glue has dried rock hard you will probably need to use an angle grinder to remove it.
