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:ive been waterproofing basements for 13 years. we jackhammer concret all day and the basements get very dusty. masks are worn but their not 100%
- as you know, when cement dust mixes with water it turns into cement when dried...now your lungs have moisture in them and when you breath that stuff in it mixes with the moisture in your lungs. so when you breath it in it can turn into cement in your lungs...so its not good at all. make sure your mask is on properly and never work with cement without a mask on. =]
- Q:I've had dental implant placed, and today I have seen my dentist who installed the permanent crown. He cemented it with temporary cement. He reasoned that by if he fills it with permanent cement, then in case anything happens in the future and has to be looked at, then he has to quot;breakquot; the crown and thus new one is needed. However, that is not the case with temporary cement. Is he doing the right thing? I am honestly not convinced too much. He
- I've never heard of anything like this, especially when inserting a permanent crown for an implant. Your dentist seems a little unsure of what he's doing. I mean, if you always anticipate your work to have problems in the fututre and for anything to happen then things will definitely happen when in reality they shouldn't. An implant that is done right should last your whole life, A crown that is done right (and assuming to take very good care of your teeth) should last 10-20 years (although I've seen some crowns last 50 years). I personally find it a little odd that he cemented a permanent crown with temporary cement.
- Q:How to lay cement blocks?
- Remove 4-6 inches of soil/sod, lay geotech fabric, compact 4-6 inches of D-1 gravel in 2 inch lifts, grade to drain away from structures, screed 1 inch of sand or stone dust and lay blocks on sand. Tap with rubber mallet then sweep sand into the cracks.
- Q:I'm a student, now studying about derivatives. In type of commodity options, why do we have wheat options, oil options, gold options... why don't we have cement options?And please let me know, is there any qualification, any criteria for choosing a goods to be an underlying asset of a derivative?
- Don't be intimidated by the charts, actually they are not that hard to read and understand. Strategies that are based on reading and analyzing charts are part of the technical analysis area.
- Q:So, long story short, i broke a nice glass bowl and tried to find super glue, all i found was quot;vinyl cementquot; so i looked it up and it said the fumes are flammable. so is it ok so smoke out of it after it completely dries?
- Define 'smoke out of.' I'm not sure what the auto-ignition temperature of the vinyl cement you're using is, there's probably an MSDS sheet on it available from the manufacturer. Depending on how much you're using, I'd be more worried about breaking down the cement with heat and inhaling any off-gassing/fumes. But its probably fine. EDIT: Also, vinyl cement probably won't work. The vinyl cements I'm familiar with use a chemical reaction with the vinyl to create heat and fuse/melt the two pieces of vinyl together. Since glass isn't vinyl, it probably won't hold (for very long, at least).
- Q:how to remove white cement?
- Only way is to use a hammer and chisel. It would have been easier if you said what the white cement was on. Is it a driveway? or cement splattered on something.
- Q:What is the difference between lime and cement in building materials?
- What is the difference between lime and cement in building materials?
- Q:what are the best roller derby wheels for cement?
- it depends....is the cement painted or polished? is it usually dirty? these can make it much more slippery than it would be if it is none of these. I skate on a polished cement track which was covered in epoxy and is super slippery. I use Sugar hybrid wheels because they are super grippy. If the cement isn't polished you should probably use harder wheels.
- Q:okay so i wanted to make a rocky background that would fit my tank specifiaclly. the only thing in the tank is a fire belly newt. what kinds of cement are safe to use for that purpose or are there any like sealants that you can put over the cement so that chemicals wont leak out into the water?
- Its not chemicals that you need to worry about with cement (I take it you are referring to concrete?) its the pH balance and the alkalinity of the water you need to worry about, as concrete is made of limestone that will dissolve in the water and raise the hardness and alkalinity of your tank. If you have South American fish like tetras that prefer soft, slightly acidic water, concrete landscaping will not be appreciated. African cichlids, which prefer hard, alkaline water, will have no problem with this arrangement. You can use any epoxy putty to adhere fixtures in your tank together. Most pet stores will also sell tubes of aquarium sealant that is 100% safe when dry.
- Q:A 20 pound bag of Economy brand cement mix contains 25% cement and 75% sand. How much pure cement must be added to prduce a cement mix that is 40% cement?
- Let x = amount of pure cement (note that pure cement is 100% cement). You are given that 20 = amount of 25% cement. The new mixture (40% cement) will be x+20. Now insert the percentages. (100%)(x) + (25%)(20) = (40%)(x+20) 1x + 5 = 0.4x + 8 Subtract 0.4x from each side 0.6x + 5 = 8 Subtract 5 from each side 0.6x = 3 Divide both sides by 0.6 x = 3/0.6 x = 5 Answer: 5 pounds of pure cement
