Q:Fiber-cement siding?
Only con is it is difficult to cut, need to purchase the correct saw blade. It is very stable with changes in temperature, unlike vinyl siding. It does have a similar appearance and will increase the value of your home more than vinyl would. I think that vinyl should decrease the value, it is just not a good material for siding. Have worked many days on repairing vinyl siding that is coming loose. I plan on using cement board siding when I replace the siding on my home. Price is very good right now for cement board, about the same price as the cheap masonite lap siding.
Q:what properties do plastics have that makes it possible as a modifier in making cement?
It wouldn't be bulk (solid) plastics that would used in cement modification, it is more likely to be polymer latex dispersions - colloidal dispersions of small spheres of polymer, the material resembling a white milky liquid. The dispersion is water based, as is cement mix, so the two can easily be combined, and then when the cement dries and sets off, the interior of the porous structure of the cement block will contain a monolayer of the polymer. They are often used for imparting moisture resistance to the concrete, and also a degree of flexibility which reduces environmental degredation.
Q:Can you lay cement board in order to put vinyl flooring?
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.
Q:I have a crack in my basement's cement wall, the crack runs the entire length of the wall. how do I fix it?
You can buy a two part poly injection system on line that will fix the crack.After the crack is fixed fix the 12x12 area with a vinyl concrete.
Q:What is the significance of silicon dioxide in portland cement?
Allow me to qualify my answer first. When mixing cement water, in the process and as it dries hardens, air pockets tend to form inside the concrete. Air pockets are like those holes that are inside the cheese we see when we cut it. Concretes could also tend to form air pockets as it dries up firms up. Those air pockets could WEAKEN the concrete, because of the spaces inside. Now, the function of silicon dioxide is it minimize those air pockets tends to make concrete stronger.
Q:Is blacktop or cement cheaper? I have a gravel parking space that is about 10 ft long and 30 ft wide.?
think that the width of the strip of grass is x. in case you draw this out, including the strip of grass each and each of ways around the rectangle will upload 2x to the two between the size and width of the rectangle. So, the mixed area of the pool and the strip of grass is: (20 + 2x)(30 + 2x). the area enclosed by the pool is in basic terms (20)(30) = six hundred, so the area of the in basic terms the strip of grass is: (20 + 2x)(30 + 2x) - six hundred. we would like this to equivalent 336 feet^2, so we've the equation: (20 + 2x)(30 + 2x) - six hundred = 336 ==> 4x^2 + 100x + six hundred - six hundred = 336, by FOILing ==> 4x^2 + 100x - 336 = 0, by putting the wonderful part equivalent to 0 ==> 4(x + 28)(x - 3) = 0, by factoring the left part ==> x = -28 and x = 3, by the 0-product belongings. because we the strip of grass won't be able to have a detrimental width, x = 3 is the only existence like answer. as a result, the strip of grass could be 3 feet huge. i'm hoping this permits!
Q:using cement in construction...........?
Cement is produced with the main purpose of binding aggregate (sand or gravel) to make concrete or mortar. The aggregate adds to the strength of the mixture. Romans used a similar mixture to what we use today and a lot of it is still standing strong.
Q:How can I keep cement from cracking while it dries?
No matter what, a sidewalk repair will always crack along the same crack line. One cannot prevent this as the forces of expansion and contraction are along that line and the repair will always crack again. Cement does not dry. Cement polymerizes with water and the water becomes a permanent part of the cured cement itself. On your repair project, take and mix about 5 tablespoons of Latex paint to a batch of repair cement. This will prevent rapid curing of the cement and improve the bond onto the old concrete sidewalk. When you have finished the repair. Cover the repair with corrugated cardboard, two to three layers of it and soak it down. Always do a repair in the late evening as possible to keep the sun off of it.
Q:What do you fill a hole in the wall with cement or with putty? And does cement come already mixed?
Hummm - generally you use plaster of some kind. Cement is great on older places where you have lath and plaster - but it's only for filling a LOT of holes at once. It's too messy for just a little hole. And no - cement needs to be mixed - and generally you buy it in a HUGE bag. You can get a little container of some plaster or Spackle or something like that from the hardware store. If you really have a hole right through your wall, then you have to shove something in the hole to sort of close it up - like screw a little stick in back of the hole.... then you put some spackle on it several times. Try not to heap up the spackle - just fill the hole and let it shrink - and put some on the next day. sometimes takes three or four coats. This stuff is so easy to fix once you do it for a while - but it's pretty hard to explain it to anybody.
Q:Hanging on cement?
Hook and loop (velcro) tape. Glue one side to your item, and one side to the cement....larger pictures will need tape around all four edges to be secure, but it does work - I've done it before. Hope this helps. Good luck!
