Q:how to break big pieces of cement?
best bet sledge hammer easy way eletric jack hammer home depo rents them good luck
Q:how can i repair a cement block that a beam (2X12X16) rest on it.?
You did not give much info on the cement block just the beam. How big of a block are we talking about? What is the construction of the cement block? 2,000 psi? 2500 psi? How intense was the fire? Most fires will not hurt cement blocks. How much weight is this beam holding? After you take the burnt beam off you can make a better assessment on the cement block. I'm willing to bet my last dollar, it will hold up a new beam fine. Good Luck!
Q:what, if anything, is the difference between concrete and cement?
Cement is made from ground and fired limestone and gypsum. It is a fine dry powder and when water is added can be a glue-type material. Concrete is a combination of cement, sand, gravel and water. When combined in specific proportions this combination makes concrete.
Q:Cement or Concrete?
Technically, cement is what hold concrete together; concrete is an aggregate of sand, cement (usually Portland cement) and gravel. You can use pure cement as concrete if you want to, say, to fill cracks, same way you might use wood glue to seal up cracks where pieces of wood come together. Generally, fully cured concrete is stronger than cement by itself. I need to know more about the backyard box to recommend a specific approach. How big, how deep, above ground/below ground...etc.
Q:does fiberglass stick to cement?
Fiber glass will not stick to cement and also due to material properties they expand and contract at different rates. But saying that, i think ur idea might work. I think it would be simpler and probably cheaper to fill the whole a non shrinking mortar then painting the inside with an epoxy based paint. That would give you the best of both worlds
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 make reference to the wall being concrete , so I will assume it is a poured wall rather than a block wall. If the wall had just a simple crack, chiseling out the crack about a half inch deep and filling with a Hydraulic cement would work fine. What concerns me is that you say a 1/2 inch X 1ft. X 1ft area has come off. Crumbled I would suspect. The structural integrity of the wall has been compromised by excessive dampness. Basically turning the concrete back into sand. First thing you should do is stop the dampness. This could mean sloping the grade away from the house. Extending downspouts to 3 or more feet beyond the house. Maybe even putting in a sump system. If you don't, any repair you do will not last and just fall off at a later date. I strongly suggest you get a professional to look at it. Hopefully that area is not badly deteriorated. Deal with the problem first, then the consequences of that problem. Once that is done the wall can dry out. Scrape the area with a chisel, then wire brush. Clean the area with a cement etching product, (found at your local home depot) then trowel on the same hydraulic cement mentioned earlier. This product can be applied even when the wall is still leaking and works well, but if you can, do the prep work. There are real good wall waterproof paints available. They are really thick and rolls on like a paste. Works great though. Good luck........
Q:How do I build a fish pond with cement?
Go buy a good piece of EPDM roof rubber for a liner. To get technical you can not make a pond from cement. You can use concrete, which is a mixture of cement, sand and aggregate. But you would also need to use steel reinforcement. And if your in a cold climate you half to allow for freeze-thaw, and expansion and contraction. I think in the long run you would be wasting money, I have EPDM roof rubber in my pond and its been in for over 4 years with 10 tons of river rock placed on top of it. Or you could talk to a swimming pool contractor. They use Gunite, which is a concrete that is sprayed onto steel reinforcement. There are only three things for sure with concrete #1 It comes in a truck, #2 It gets hard you hope, #3 It cracks
Q:What's the difference between concrete and cement?
Concrete is cement that contains stones, gravel sand.
Q:How can you make cement boat float?
Just displace more water than the boat weighs.
Q:Swelling after cement filling?
Take him back to the dentist just to make sure theirs no infection or anything
