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: our prank is to dig 1 foot wide/1 foot deep trenches shaped like ***** and fill with cement, so how do we fill it cement, can we pour the powder stuff into the trench and fill with water then mix it with a stick, and dont tell me i shouldnt do it, or its mean, i dgaf, we have a full-proof plan, we just need to know how to lay cement
- Usually, you mix it in a wheel barrel then poor it.
- Q: My parents had a new cement driveway put down last summer, and accidentally used a non-safe-for-cement salt, and now it is flaking in small areas. Can this damaged be repaired by some kind of patch or filler compound - or is the damage permanent.
- Salt Cement
- Q: What is the meaning of 53 grade cement ?
- The grade of a portland cement corresponds to how much pressure it can take after it has set for 28 days. 53-grade cement must have a compressive strength of 53 MegaPascals (7687 pounds per square inch) after 28 days. There are also 33 and 43 grades, which must have minimum compressive strengths of 33 and 43 MPa respectively.
- Q: Final setting time of cement...?
- First is the 1st 24 hrs which then you can walk on the slab. 2nd is the next 7/8 days after which you could drive across and the final setting time is the next 30 days for the slab to cure. GL
- Q: 1)what do you mean by portal cement? 2)wt is the meaning of analar element? tnx.?
- Portland Cement is cement made using limestone from Portland, Dorset, England. Analar is a mark meaning very high grade of purity. I expect it stands for analytical reagent.
- Q: Thinking about playing a trick on my kids with little footprints on the cement porch. Would food coloring wash out, or should I use something else?
- You would likely have to use something that is water soluble because cement is porous and will absorb liquids on its surface. If it were me, I wouldn't use food coloring, I'd use water color paint. You could probably find it at a hobby store. If the cement area where you are planning this caper is exposed to the weather, the footprints should disappear after a short time. If they need to disappear more quickly, some diluted bleach would speed the process along. You can also speed the process of making the tracks by making a stamp from a potato. Just carve enough away from the potato to leave a mound that sticks out/up in the shape you want the tracks. You can then just dip the potato into whatever colored mixture you decide on, and quickly stamp your tracks on the cement. That would be quicker than drawing the tracks if you're planning on quite a few tracks. Good luck with the prank!
- Q: can anyone give me powerpoint presentation on the topic cement.it includes manufacture+properties+...............
- Cement, or Portland cement, is defined as a hydraulic cement, obtained by burning a mixture of lime and clay to form a clinker, then pulverizing the clinker into powder. The greenish gray powder is composed primarily of calcium silicates, calcium aluminates, and calcium ferrites. When mixed with water (Hydrated), it solidifies to an artificial rock, similar to Portland stone. A Portland Stone is a yellow limestone from the Isle of Portland, in Great Britain. Historically, cement can be traced back to the early Roman Empire, and contributed to the building of the great structures of the Roman Empire. By varying the amounts and types of the same basic ingredients, cement with various properties may be obtained. By further varying the ingredients, even more differing cements are manufactured. *Cement manufacturing is the basic processing of selected and prepared mineral raw materials to produce the synthetic mineral mixture (clinker) that can be ground to a powder having the specific chemical composition and physical properties of cement. Cement manufacture, like many other manufacturing processes, begins at the mine, where the raw materials like limestone, silica, aluminates, feric minerals and others are obtained. Some typical materials used for calcium carbonate in cement manufacturing are limestone, chalks, marbles, marls, and oyster shell. Some typical materials used for alumina in the cement manufacturing are shale, clay, slags, fly ash, bauxite, alumina process waste, and granite. Some typical materials used for silica in cement manufacturing are sand, clay, claystone, shale, slag, and fly ash. Some typical materials used for iron in cement manufacturing are iron ores, blast furnace flue dusts, pyrite clinker, mill scale, and fly ash.
- Q: Hello.Can you tell me how cement, concrete and glass is made? And if possible, adding a bit of history into it?
- the generic term cement simply means binder or glue; hydraulic cements are those which bind and harden in the presence of water. Early construction cements were usually clays mixed with an aerated volcanic rock called pumice; later mixtures included chalk (a high grade limestone composed of coccolithic (spherical stones) carbonate structures. What we commonly call cement and mostly use in construction and landscaping today is a type of cement called Portland cement, which was accredited to Joseph Aspdin in 1824; a mixture of ground (often low grade, or impure) limestone and clays containing aluminium sulfates. Gypsum (hydrous calcium sulfate) may be added to the mixture if more sulfates are needed. Concrete is an artificial conglomerate (in geology, a conglomerate is a rock made up of often metal-rich stones set in a matrix of sand and fine clays) where the binding matrix is composed of (usually) Portland cement and clean sand, and stones (commonly called gravel or road metal); without the stones, the mixture can be a mortar (used to bed and bind bricks or blocks) or a render (a thick paste used to dress bricks and blocks). Glass is commonly composed of melted quartz sand (silica); limestone is added to the silica to prevent recrystallisation when it cools.
- Q: Tell me about PVC cement glue?
- The cement should be applied on both the pipe and the inside of the fitting. Primer should be used to get the best results. Once both surfaces have glue applied, slip together and twist 1/4 turn while pushing inwards. Hold for 5 seconds and your done. CPVC needs a different type glue that is made especially for it. CPVC is used for hot water lines while PVC is for cold water and drainage lines. Getting it off your hands is a chore. Use the brush that is usually contained in the can lid.
- Q: We want to remove the carpet and install wooden vinyl flooring. We were thinking about putting cement board in order to make the floor flat.We were thinking that it would be a better option as oppose to laying the flooring on the wood. Would it be a good idea to lay down cement board?Should we just lay the vinyl on the wood?
- I would not put down cement board. If you want a smooth surface to lay the vinyl over (any lump, bump or irregularity will show through vinyl) use plywood.
