- Q: How long should I let new cement cure before I can build on it?
- Yes, watering will help the curing of the concrete, not making it faster but reducing shrinkage cracking due to the loss of moisture at the surface. You can either set up a light sprinkler to keep it wet, or use wet blankets. Generally, concrete should be allowed to cure for at least 3 days before you build on it. This is dependant on the strength of the concrete you placed and the load you will place on the concrete. The concrete will reach it's design strength within 28 days, with very minimal gains after that time. Make sure you allow the surface to dry if you are water curing the concrete before you begin to build.

- Q: I have a cement statue and the finish has worn off. How can I repair it myself? What product can I use?
- I assume that your stature is outside, but if it's inside that will be even better. I have a cement bird bath with a stature of a lady in the middle that time had worn badly. While not valuable, it came from my wife's mother and she wanted it fixed. I repaired it using motar mix from the building supply store. However the finish was not as good as the original. If your stature is inside and you want a professional finish, you may want to try Bondo or something similar and paint it after repairs. Good luck.
- Q: i buried my two parakeets in a white cement tomb (2 compartments for the 2 birds) Since white cement is.. cement, will the stench of their bodies decaying inside be also smelled from the outside? They're just interred so I still don't know what will happen- will i smell the odor or not? and when I touch the cement tomb, is stick to my hand as duslike powder so it quot;erodesquot; away. Anyway I can stop this erosion of the cement? Thanks to the one who can answer my problem :) Hope you understand my love for my pets to make them a white cement niche even if it sounds weird :)
- You must love your pets very much to make them a nice place for burial. How do you feel about painting the tomb? If you paint the white cement tomb you will not smell any odor and it should stop the erosion of the cement. A good paint to try is Kilz. They have a line of paints and primers that offer superior coverage, mildew resistance and tough stain and odor blocking. I am sorry for your loss. I hope this helps.
- Q: Can cement be mixed with sea water instead of fresh water?
- The best practice is to use potable (fresh) water for a concrete mix design. If you are somehow left without another option the following information should help you make an informed decision. If the situation is regarding a structural portion of a home, business, bridge or otherwise important structure please seek a qualified engineer to help give you more specific information. If this is for a small project like a mailbox foundation or similar then I hope this information will be helpful in making a good choice. The answer depends on your steel reinforcing. If the concrete you are preparing the cement for will have steel reinforcing you will need to use corrosion resistant steel (such as stainless steel, MMX, epoxy coated, or galvanized) if you want to keep the steel from corroding prematurely due to the salt content of sea water. If you decide to use sea water in the mix and have steel anchor bolts embedded in the concrete, you will want to make sure that they are stainless steel or galvanized. Make sure that you use the same steel type (stainless or galvanized) for your bolts, washers, and nuts. Ultimately the saline properties of sea water will produce a harder concrete, but if that corrodes your steel your end result could be a dangerous failure. Your first choice should be to use fresh water in all but very special cases.
- Q: what are some pro and cons
- Cement counter tops are more expensive than Granite, per square foot. Very labor intensive to build. You then need a good sealer and need to be careful about stains.
- Q: What is the total weight of a cubic meter of the mix? what part is cement? stone?sand? add these fractional amounts.what is the result? 420+150+120=690Kg, total 690 -420 used what part =n 420/690divided by 10/10=42/69divided by3/3=14/23 cement, how do you figure out stone and sand?
- Cement = 420 / 690 = 14 / 23 Stone = 150 / 690 = 5 / 23 Sand = 120 / 690 = 4 / 23 Total fractions = 14 / 23 + 5 / 23 + 4 / 23 = 23 / 23 = 1
- Q: What is a chemical that softens rock and cement?
- Hydrochloric acid softens cement. You can buy large containers of it for removing cement from brickwork. It will also attack some types of rock, especially limestones. Be careful with it though!
- Q: Can ANYONE answear this????? please no one can seem to....ok so to make cement, you add limestone, clay and sand i think? :)so what is the chemical and word equation for this?Thank You soooo much:D
- Cement is made by heating limestone with clay in a kiln CaCO3 + clay (clay is not represented by a chemical formula) (arrow) cement
- Q: Is a Cemented or Uncemented Prosthesis Better?
- The response to this differs for various people. Because each person’s condition is exclusive, the physician and also you must weigh the pros and cons. Cemented substitutes tend to be more commonly used for older, less active people and individuals with weak bones, for example individuals who've brittle bones, while uncemented substitutes tend to be more commonly used for more youthful, more active people. Research has shown that cemented and uncemented prostheses have comparable rates of success. Studies also indicate that if you want one more hip replacement, or revision, the rates of success for cemented and uncemented prostheses are comparable. However, more lengthy-term data can be found in the U . s . States for stylish substitutes with cemented prostheses, because doctors have used them here because the late sixties, whereas uncemented prostheses weren't introduced before the late seventies. The main drawback to an uncemented prosthesis may be the extended recovery period. Since it requires a very long time for that natural bone to develop and fix towards the prosthesis, you aren't uncemented substitutes must limit activities for approximately 3 several weeks to safeguard the stylish joint. Also, it's more prevalent for somebody by having an uncemented prosthesis to see leg discomfort within the several weeks following a surgery, as the bone keeps growing in to the prosthesis.
