- Q:I need to know what cement to use for my shower pan and how to mix it.?
- well sand and cement(portland cement) roughly a 3 to 1 mix 3 parts sand to one part cement. Mix it fairly stiff as in no alot of water, then lay it down and tamp the the shower tray into position check for level, and your good to go. am on e mail if u get stuck
- Q:Please any one says me Chemical composition of Portland cement?
- Typical constituents of and Portland cement Mass% Calcium oxide, CaO 61-67% Silicon oxide, SiO2 19-23% Aluminum oxide, Al2O3 2.5-6% Ferric oxide, Fe2O3 0-6% Sulfate 1.5-4.5%
- Q:Why there aren't any cement options?
- Well, first off we don't exactly have wheat options, oil options, and gold options. We have wheat, oil, and gold futures options (there probably exist options on these cash commodities but they aren't exchange traded and would generallynot be available to joe investor). If you are trading options on these commodities, upon exercise of the option you receive position in a futures contract not a position inn the commodity. That means your question is really, why aren't there cement futures contracts. The answer is: a) They have thought about them in some places at various times. A couple of years ago, they tried to get one going in India but some regulatory board nixed it for reasons unknown to me. b) Cement prices are relatively stable (and low). Cement sells for $100/ton (I think) and just doesn't vary much. c) Partly because of b) there is no need to hedge cement and a commodity with very stable prices would not entice many specuators. If the price of something is currently stable, introducing a futures contract and speculation to try to maake the commodity price unstable so people will hedge it and use futures contracts would be terribly abusive to the economy. d) Cement is usually a small component of the price of any project using large amounts of cement. The big expense is usually the construction expenses surrounding the cement and moving concrete. Thus, even if cement prices were variable, the variability would only contribute to variable costs of a project in a samll way and so probably not be worth hedging. e) If CBOT or CME thought it would be successful and they could get CFTC to go along with it they would offer cement futures in a Chicago second.
- Q:can you put hydraulic cement over a painted cracking cement wall?
- That sounds more time consuming than just scraping off the peeling paint..... Here's 1 problem w/your approach, latex paint dries so fast that it actually creates a vacuum effect in doing so, which means that as it dries it'll pull off the surface anything that's not firmly attached, which is why prep work's so important to longevity. You won't immediately notice this happening, but w/the passage of time you'll be back to the peeling wall in spades. I've never heard of skim-coating w/hydraulic cement, but I've done plenty of patching plaster walls w/plaster of paris, what immediately comes to mind are the inherent problems w/working in a medium that sets up so quickly, I can't imagine how you'd get a whole wall covered looking even satisfactory (but I'm pretty picky, I figure when people are paying me I'm obliged to do a better job than they could've) w/out going insane in the process. I learned the trick to plaster, but I don't know the chemistry of hydraulic cement well enough to find a retardant for it. Anyways, I know prep-work sucks, but often it's just easiest to do it get it over with (start w/a stiff putty knife, by the way) rather than inventing a new process having to deal w/a long string of learning curves as you go. The first question that came to mind w/your question is have you ever skim-coated anything before so that you'd have even a vague idea of what you're getting yourself into potentially, but if you must create, than by all means go forth!
- Q:what is stronger than plaster but lighter than cement?
- Aerate the cement and it should hold most of its structural integrity as well as reduce the overall mass.
- Q:put down cement backerboard without adhessive?
- You should use both screws and an adhessive or mortor. Without adhessive or mortor, your floor will likely over time begin to make noises and could cause grout cracking due to settling. Mortor is cheap and quick. Good luck!
- Q:whats the differenc`e between concrete and cement?
- Concrete is a mix of gravel, sand, and cement; the exact proportion is governed by the desired end use. Often there are some other additivies depending upon the exact end use. Cement, usually portland cement is one component of concrete. I could go on and on about the chemical nature of portland cement, how it is made, why it does what it does as well as discuss what it does but that would require a lot more space than this forum allowes and a lot more ambition than I have to type it all in.
- Q:What paint do I use to paint over cement render?
- First, try using a power washer in the 2000 PSI range to take off the old paint. If it comes off (or most of it, anyway), let the cement dry for a couple days and then use a concrete primer before applying a color coat specifically made for concrete. The primer is especially acidic, so it really soaks into the cement (and it doesn't go very far, because so much soaks into the concrete). The concrete color coat is then designed to hold onto the primer and provide a solid moisture barrier. If the old color won't come off, don't worry. Just clean it up as best you can before applying the primer and paint. And, use top name brand paints (like Dunn-Edwards or Sherman Williams). The more expensive products will cover better and may actually be cheaper in the long run (less coats and time to paint).
- Q:advantages and disadvantages of cement to people, or even the environment?
- IT IS VERY HARM FULL
- Q:Is the cement industry in the stock a separate plate? Or part of the other plate?
- Follow the concept. The The LZ satisfaction to the too fast, I am very dissatisfied, I believe you have to see my answer will be more satisfied
