Q:what is cement ? this for a scince project we have to do this.?: What is White Cement? (PDF) centers from coast to coast, white cement is. readily available throughout North America. Specifying White Cement. Color is a very important quality control issue ...cement.org/bookstore/download.asp?med...

Q:How is cement made and what is in it?: Let's work backwards... CONCRETE is Cement, water, sand and aggregate (gravel or rock). When the water is added to the cement, sand and rock, it forms a chemical bond that turns it into concrete. It does not dry but rather cures. You can pour concrete under water. Mortar is cement, sand and water. No rock. It is used to bind brick together. So, Cement is the common item. Cement (also called Portland Cement - that name comes from it being similar to stone that comes from the Isle of Portland, in Dorset, England ) is made by heating LIMESTONE in a kiln, the result - called KLINKER - is then ground into a fine powder and some Gypsum is added. That is than bagged as Cement.

Q:The cement I'm wondering about it 3 feet deep and 2 feet wide. I'm wondering how long it takes to dry completely??Thanks!: it could take up to a week for how deep it is

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.

Q:I have recently built a brick bbq and the cement/sand between the brick has gone really dry and a very light grey colour - nothing like the colour of the cement between the bricks on my house. I think it may be because I have too much cement in the sand to cement ratio, which is approx 3:1 respectively. Can you help?: probably the house builder added a colorant to the mortar, which makes it darker. You can actually stain the dry cement on your BBQ (with wood stain) or add a matte sealer, which will darken it some.

Q:I need a 20 ft by 16 ft concrete pad for a pavilion. Should I use a concrete truck or quikrete? Costs are a factor.: Wasn't going to chime in on this one. But after reading what people said I figured giving you my experience would possibly be helpful. I had a large pad to pour. Not as big as yours but way bigger than I wanted to do by lifting bags of concrete into a mixer. I had that option and two other options. One you mention is to have a cement truck deliver it and pour it. Provided it can get close enough to do the pour OR you will have to run a wheelbarrow brigade back and forth from the truck to the pour site. A third option (and the one I went with) was to buy concrete ready mixed in one of those portable mixers. I bought 2 1/2 yards of concrete and towed the trailer home. It cost less than buying all those bags of concrete - so that made for an easy decision. Plus not having to hoist all those 80 pound bags into the mixer. The BIG truck would have cost about the same for the concrete BUT I would have had to pay a delivery charge. So I went with the trailer mixer and was able to pour out one wheelbarrow at a time and get the job done. All without having to do all that lifting or paying for delivery charges. Consider that. Hope this helps. 'av'a g'day mate. )

Q:i know it's by adding water but what happenes to it tom make it turn into cement?Thank you!: I worked a summer for them while in college.) If you read the info you'll learn how rock is ground into cement and what additives go into the mix to change it's characteristics. Some additives make it harden faster or slower, some give it color, some do other things. The basic ingredients for concrete are cement, sand, aggregate, and water. The proportions of each make different quality of cement for different uses. Check it out.

Q:The wind knocked over part of our wood fence. Two of the wood posts that were cemented into the dirt were uprooted. I figure the best way to fix the fence would be to use new posts (or bust off the old cement) and bury them in the ground with fresh cement. I'm feeling lazy and wonder if I do as good of a job just burying the old posts with the old cement back into the ground. Will it hold? Maybe this is a no-brainer for some folks - useful comments appreciated.: First off if the wind blew the fence down then maybe you should go alittle deeper with the post. As to your next question, even though your feeling lazy it is best to knock out the old stuff (concrete) and pour new concrete post mix. If not then it is highly likely that you will be doing it again. Its pretty easy but time consuming. Good luck

Q:As there are many types of cement, i want basic types of cement: Type 1 - Normal portland cement. Type 1 is a general use cement. Type 2 - Is used for structures in water or soil containing moderate amounts of sulfate, or when heat build-up is a concern. Type 3 - High early strength. Used when high strength are desired at very early periods. Type 4 - Low heat portland cement. Used where the amount and rate of heat generation must be kept to a minimum. Type 5 - Sulfate resistant portland cement. Used where the water or soil is high in alkali.

Q:Just for kicks I tried to live up to my name a few days ago. So, I threw a party, and for the grand finale I tried to pick up one of those cement parking curbs and give it a good heave- ho. Long story short- after 3 of my buddies lifted the dang thing off of me, they drove me to the hospital... and my back aint doing so good. Stupid me for trying, or a man of his word?: I'm going to go wayyyy out on a limb here and guess that cement curbs are heavy... BECAUSE THEY'RE MADE OUT OF CEMENT! I won't be as harsh to say that you are stupid - we are all capable of making poor decisions... and that was one. I do hope your back gets better, though.
