Q:This isn't for me, my bf is redoing his new house and he got cement on his hands, but didnt wash it off in time. it's been a couple hours right now, and he tried soap and water (like that'd work lol) and oil. I suggested a nail file to get it to flake off, but he doesnt have one.would that work?please tell me if there's anything that'd work. some sort of solution or a file or something? or will he have to go to the doctor and like, get it peeled off or something? lol
Yikes! Your boyfriend needs to go see a doctor for this. The cement on his skin can cause a chemical burn, and he needs to get it off. It's important that he go now, even if the only place open at this hour is the Emergency Room. If at all possible, he should bring the package that the cement was in so the doctors can see for sure what they're dealing with. Also, if your bf has access to the Material Safety Data Sheets (MSDS for short) for the cement, he should bring that to the hospital too. Actually, the MSDS would probably be the more useful thing to bring if that's all he has access to. He might insist that it's no big deal and that his hands will be fine. Guys like to act tough like that. Ignore him and drag him to the hospital if you have to. ;)
Q:i was told not to use anything that would seal the cement, and that the object needs to breath.
You can use the outdoor acylics that are in the craft stores. Just paint the top and leave some of the bottom open you won't see. I don't see the problem though- I painted a hopscotch on the sidewalk on the side of our home for my daughter-7 years ago. Its still there-no sealing. Check out liquitex and other main brands-ask the store/girls for suggestions.
Q:i know it's by adding water but what happenes to it tom make it turn into cement?Thank you!
First of all its Portland power and then aggregate (rock) and a little sand. when its mixed a chemical reaction occurs and it binds it all together and dries then its cement
Q:cement?a. 150 poundsb. 100 pounds c. 50 poundsd. 112.5 pounds

Q:is a backhand spring on the grass any differant than a backhand spring on cement? does it hurt? i realy want to do it on cement after i get it on the grass. any help?!
yeah, cement is much harder it doesn't have as much give and if you fall and hurt yourself falling on the cement will hurt more.
Q:When preparing mortar, why in addition to cement, but also often add a certain amount of other cementitious materials
Gel material in the physical and chemical effects, from the slurry into a solid stone, and can cement other materials, made of a certain mechanical strength of the composite solid material
Q:i would like to know how the cement grade be checked? kindly let me know what other test can be done to know the quality of cement?
Don't usually check the portland cement, usually you test the concrete mix to assure it gives you the strength you desire. This is usually done with actual breaks of cylinders made from the mix you want to use, done before the mix design is approved. Then, additional cylinders are cast while placing the concrete and tested at intervals over a 28-30 day period to make sure the concrete strength meets your requirements. The exact number of cylinders is usually decided by the owner or engineer, based on the amount of concrete poured at one time. The minimum number of cylinders is usually 3, one to break at 3-7 days, one to break at 28-30 days, and one spare.
Q:Are they like the same...different? Idk
Cement is the stuff that binds the aggregate together. A common type of cement is Portland Cement. The stuff is like sand. It's not hard and it can come in bags. You can pour it out. When you mix cement with water and aggregate then let the mixture set, it becomes hard, almost like stone. It becomes concrete. After it has hardened, you can drive a tractor trailer over it or build a fairly tall building on top of it.
Q:And how would you do that?
Either a hobby shop or if you are near a major retailer (WalMart, Target, KMart, etc.); go into the toys section, find the models and you'll see tubes called model cement. It's a special glue.
