Q:Why does cement hardens when exposed with air and water?
Cement does not need to be exposed to air to harden. It can cure under water! This is why it's called hydraulic cement. Curing is one of the most important steps in concrete construction, because proper curing greatly increases concrete strength and durability. Concrete hardens as a result of hydration: the chemical reaction between cement and water. However, hydration occurs only if water is available and if the concrete's temperature stays within a suitable range. During the curing period-from five to seven days after placement for conventional concrete-the concrete surface needs to be kept moist to permit the hydration process. new concrete can be wet with soaking hoses, sprinklers or covered with wet burlap, or can be coated with commercially available curing compounds, which seal in moisture.
Q:Fast drying cement or substitute?
the cement probably stops before the end of the property. The telephone pole is on the road edge. You do not cement there. It is owned by the city...so cement (which is permanent) is not allowed. Any reason you cannot get a hold of some 2x4x8feet long and lay them in the trench in front of the cement? Otherwise a diamond saw and chisel down your driveway closer to the road. It was badly poured, plain and simple. Or you could wait till it rips off the oil pan.
Q:Do i need backerboard if im installing ceramic tile on top of a cement basement?
woodtick gave you exactly the right answer,,, existing cracks in your slab WILL transfer through the tile work fairly quickly.
Q:How long does plastic roofing cement take to dry?
It's supposed to stay liquid/flexible and self sealing. It;s not designed for large gaps the way you used it. If you're stuck for a patch, try a few layers of aluminum foil coated and fixed in place with that cement to close the gap. Not as good as replacing the flashing, but better than what you've got.
Q:how much cement will it take to fill a 5 gallon bucket?
If you are going to use straight cement one 80 lb. bag, 2/3 of a cubic foot, will fill your five gallon bucket, with some left over because of the present. Five gallons is 2/3 of a cubic foot. If you are going to use a mix with aggregate and water a gallon of cement will be more than enough.
Q:building a pond, instead of pond liner using cement, will this work?
Concrete is unforgiving and will crack. And it is not repairable. I recommend using a flexible liner no matter where you live. It's cheaper and will last for 20 years at least. Sealing the concrete adds another huge cost to the building of the pond. Stick with a butyl liner.
Q:What cement stick to tile glue?
one minute
Q:Attaching studs to cement?
There are concrete nails/screws/fasteners -- check at your local hardware store. Studs are either 16 or 24 on center, meaning measured from the center of one stud to the center of the next.
Q:is that a thin set of cement?
Use Hardibacker and seal the seams with tape and thinset. Use thinset to set the tile using 1/4 spacers. I have used and recommend that you use a tile sealer to seal the slate prior to grouting and to use epoxy grout. The grout is more difficult to install but requires no sealers which need to be redone at least once a year in a shower and is well worth the initial time and effort. Be sure to read and follow the directions on the grout bags to ensure a uniform color and good grout set. MT C
Q:quikrete quick-setting cement?
The quickset has dried and irritated the skin, this is actually a mild chemical burn. I'd suggest a good hand lotion, or even petroleum jelly. Soaking them in cold water may help relieve the 'burning' sensation when it flares up. If you have any kind of 'burn ointment' it may help. If you've got a pair of vinyl gloves that will fit him, I'd slather the hands, and put the gloves on. In a pinch, you can tie a couple of ziplock bags over them, to help keep from getting the lotion, or petroleum jelly over everything else, heheh. Good Luck
