Q:how to break a cement wall with fist?
With practice. And A LOT of pain killer meds after.
Q:How many days does it take a quick sand cement to achieve its' strength on a building, bridge.?
Q:Concrete or Cement...same thing?
I think for me I could do less for my kids. I think they could be more independent if I didn't hinder it by doing so much for them rather than expecting them to do more for themselves. Don't get me wrong, they have chores and plenty of responsibilities but I do a lot of things for them that they are probably old enough to do for themselves as well. I guess I mother them too much.
Q:how much gravel and sand could be mixed for 1 bag of cement?
a bag of cement contains one cubic foot of cement...you will need 3 cu. ft. of gravel and 2 cu. ft. of sand per batch...
Q:Trivia question:: If trees are for humidity -- water is for moisture - what is cement for?
Cement is for hardenng things togther.
Q:Can I use super glue to re-cement my crown?
Please do not use superglue to restore anything that goes into your mouth guys....Dentists use a specially formulated dental cement which is made to be bio compatible with the human body. Im assuming your crown is a permanent one and if so you need to go back to the dentist and he needs to examine the issue of why the crown is not staying cemented correctly. If it is a temporary crown then I can see why it is coming loose, the cement used for temp crowns must not be too adhesive that it cannot be removed hence the reasons they can come off.
Q:How many 50kg of cement could be used for a 1 cubic concrete casting?
There are also online calculators you can try out:
Q:What glue will permanently bond rubber to cement?
Superglue will fail at the slightest touch. Epoxy would work, but you would have to sit there and wait for each one to cure. Try a caulking gun with a tube of construction adhesive.
Q:Is the cement industry in the stock a separate plate? Or part of the other plate?
Now can be considered a sub-section, there are several leading enterprises
Q:How much does it cost to pour cement?
