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.
Application
CNBM Cement can be used for all types of architectural or structural concrete construction. Such application as pre-cast panels and systems, cast-in-place, masonry units, tilt-up panel systems, roofing tiles, terrazzo floors, highway median barriers, tile grout, swimming pools, stucco, culture stone,colored masonry products, cement paints and coatings, and ornamental precast concrete items.

- Q: how to calculate quantity of cement in concrete?
- You have two ways to determine the amount of cement in a concrete. 1. From the concrete mix design. The mix design contains the amount of cement, as well as the sand, stone, and admixtures, used in a concrete. You also can get the amount of cement from the batch tickets. If you luck out, a few concrete plants use batch tickets as delivery tickets and you may find it there. However, batch tickets and delivery tickets are typically different. 2. Perform a chemical analysis on the concrete. Take a couple of cores and send then to an experienced forensic concrete testing lab. By using chemistry and compression strength of the cores, the cement content of a concrete sample can be determined. Cheers and good luck!
- Q: I am studying for an exam and I desperately need information on placement issues and pumpability in oil and gas cementing. Thanks in advance
- You okorder ). Most of the published information has to be purchased through the Society of Petroleum engineers. Off the top of my head, some of the issues are being able to pump a heavy viscous fluid like cement across under pressured formations. You have to apply enough pressure to move the cement, but you have to stay below the fracture pressure of the rock formations. If you don't, the formation will break down and the cement will flow in to that zone, called a thief zone, and cement will not make it all the way up the casing. The other issue is keeping casing centralized in the wellbore so that cement will be placed evenly around the casing. If the casing is not centered, then the cement may not might not completely encase the casing, leaving void spaces where channels can form, where oil and gas could flow.
- Q: What is water/cement ratio?
- The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix and has an important influence on the quality of concrete produced. A lower water-cement ratio leads to higher strength and durability, but may make the mix more difficult to place. I work for a construction company and i know that you always need water to mix with the concrete - in the winter you have to heat the water first and it costs more to get it poured than in the summer when you don't.
- Q: i'm replacing the old wall in my tub with hardibacker. can i screw it on the tub lip? coz the instructions said that it should be screwed or nailed 3/8quot; from the eges.
- Don't place it over the lip. Your cement board, or greenboard for that matter, should rest on top of the lip. Then you fill in the gap with thinset and mesh tape. That way the wall doesn't bulge out at the bottom on all three sides making the tiling harder to do.
- Q: if a ball was dropped on cement and an identical ball was dropped on stretchy rubber, which scenario would result in the most force acting on the ball?
- impulse = change in momentum F delta(t) = m delta(v) dropped on cement the ball would essentially lose all its momentum and the time (t) would be very short so F would be high dropped on rubber assuming a good bounce back the change in momentum would be greater because the result would be going back up at some v so impulse is greater but time would also be longer and we would have to know the time it took to bounce on the rubber and the time it took to stop on the cement to make a comparison of forces generally speaking we might reasonably expect the rubber landing to involve less force because we can imagine the difference between jumping from a height onto concrete versus jumping onto a trampoline I would anticipate that the time of contact on the trampoline would be many, many times greater than the time it would take to stop when hitting the concrete. If someone gives you a good response, please consider giving a best answer. This is the only reward we get.
- Q: How come i can kickflip on grass but not on cement?
- DO NOT do anything that would prevent the blocks from moving. They expand and contract constantly, so if you prevent movement, they will crack and it would look even worse. DO NOT use caulking, or cement. That just makes the sidewalk blocks crack, then the problem comes right back. Try some boiling water. Make sure that you do so on a hot day so that the blocks don't crack. For a temperairy job, if you have a Weed-whiper/Weed-hacker, then just use that to do it. Iff the sidewalk blocks are evenly spaced apart with at least 0.5cm of space, then that would work. If the sidewalk blocks are tight against eachother, the only way that I see fit is to get on your hands and knees and start scrubing that dirt away. It takes a lot of work, but the results are great! Then, if you can find an edger [A machine that makes a small-ish gap between the sidewalk and grass] just take back the grass so that no dirt gets back for a long while. Doing it by hand, is better because you get more of a gap, then the time will be greater before you have to do it again.

- Q: What three substances are mixed with cement to make concrete?

- Q: What percent of garnet is in cement?
- There shouldn't be any garnet in cement. Portland cement (the most common one) is a mixture of roasted limestone, clay and gypsum. None of these rocks normally contain garnets.
- Q: They all seem to refer to the same thing, is it determined based on how each is used on context or are all interchangeable with each other?
- asphalt --- A sticky, black and pretty viscous liquid or semi-reliable, composed especially a lot completely of bitumen, it truly is cutting-edge in maximum crude petroleums and in some organic deposits. pavement --- (mainly British) A paved footpath on the area of a highway. --- (US) Any paved outdoors floor, as with a highway or sidewalk. --- the interior flooring, fairly even as of stone, of massive homes including a cathedral. --- the textile with which a floor is paved. cement --- contained in the most commonplace experience of the note, a cement is a binder, a substance which gadgets and hardens independently, and would bind different resources mutually. Concrete could not be at a loss for words with cement because the time period cement refers in reality to the dry powder substance used to bind the mixture resources of concrete. Upon the addition of water and/or aspects the cement mix is termed concrete, fairly if aggregates were further.
