- Q: Ok so I want to pour cement in this, im assuming, 12 by 8 ft sized area. How mane bags of cement would I need? How many boards do I need? Do I even need them? Do I also need that wire for the bottom? How much does that run?Can anyone give an estimate of the total cost?
- My husband, who is a retired builder, said you might need around 8 bags of cement. You can get away with 6 bags, but the area you're pouring will not be as strong. To figure out how many boards you would need depends on whether the area is away from or next to another structure. Also, sand and gravel is needed to mix with the cement. Accoring to the size you're pouring, you might need one-half a ton of each. The wire mesh is supposed to be one-inch from the bottom and is placed in the cement after pouring one inch. The remaining goes on top of the wire mesh. Sorry, he cannot approximate a price for this project. Hope this helps!
- Q: I want to tile all around the bathtub alcove in a bathtub/shower. The previous people only put a small section of cement board, about 2' or less high right behind the tub faucet area. They put regular wallboard in the rest of the alcove, and the same behind the vanity area. Should I put cement board as wallboard in the entire alcove area, or only on the wall that contains the tub/shower faucets, or what it the most appropriate? Should I put green board behind the vanity area? Thanks!
- === cement board in the entire shower area and waterproof that with walls of tile === the green board is to prohibit the growth of mold in the bathroom and if you have gutted the entire room then it is best that you do the walls of the bathroom with green
- Q: when the dentist put the crown on to check to fit, he couldnt remove it to put the cement, if he did he said it'd break.it doesnt seem loose but when i bite i canfeel something happening under the crown. and when i bite down on my tongue it causes a foul odor in my mouth. im scarred :/
- To be blunt you need to make an appointment with a dentist (maybe a new one) Under no circumstance should a permanent crown be placed w/ no cement. The cement doesnt just keep the crown in place but it also seals off the tooth from infection that can be caused from outside sources. From the sounds of it, your tooth is most likely infected now. In the meantime be sure to brush, gloss, use mouth wash Sorry this happened @aspca no offense, im aware that every dentist has thier own technique; however, going by the book you arent suppose to since it can cause health concerns.
- Q: We recently replaced a basement window and the window was slightly smaller than the last one. Therefore we had to add pieces of wood to the frame to make the window fit properly. When the original window was done they used quickset to protect the window frame on the outside from the elements of the weather (where the frame would have been exposed). Should I do the same? Or should I try some type of molding?Thanks!
- if the general surface is in good condition but with cracks, may be consider cleaning out the cracks and filling with mastic, rather than sand and cement, if there is any pattern in the render see if you can match it with the mastic (which will allow some movement) then when it is painted it will look all the same. worth thinking about, it would still be waterproof and cost less in materials labour and time.
- Q: I have dark cement flooring in my garage. Today my son left a leaking mini bottle of grape juice to leak. There is a large very dark stain from the grape juice. How can I get the stain out?
- Try scrubbing the area with bleach.
- Q: quot;What date was cement made?
- 1.Cement is made by heating powdered limestone and clay. 2.It is used in mortar and concrete - mortar is used to join bricks together and is made by mixing cement with sand and water - concrete is made by mixing cement with sand, water and aggregate (crushed rock) 3.it sets and hardens quickly so building is faster. 4. Portland cement mortar was invented in 1794 and patented in 1824. It gained in popularity over lime mortar by the latter part of the 19th century and by 1930 has all but replaced lime mortar for new construction. Lime mortar was first used in Mesopotamia and was made by heating up limestone to drive out the water, then grinding it to a powder, which had sand added to it for greater strength. To use it, water was mixed to it to form a paste which slowly hardens. It was used in the Pyramids.
- Q: I need to mix 25 pounds of cement for a garden project ( a large stepping stone). In the past I have found it really difficult and physically tough to get the cement mixed relatively quickly to get the cement poured in the mold. I am mixing in a mop bucket. Does anyone have any suggestions to make this project easier?
- Use a wheelbarrow. Its durable enough to take it and it can quite easily be hosed cleaned afterwards. When mixing concrete you don't have to be too exact with measuring. Use a round top shovel and in a ratio of about 1:2:4 (1 cement, 2 sand, 4 stone). So you can try it with 2 shovel fulls of cement, 4 shovel fulls of sand, and 8 shovel fulls of stone. Blend together. Add water to the consistency you desire.
- 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

- Q: Here in the US they use sheet rock and the houses are so flimsy, but in DR they build them so strong and it's 100% cement. Why is that?
- Just an old world way of doing things... more durable. Plus, I don't think US building materials could withstand the continual beating those houses get from the salt, sand, wind, and rain off the Caribbean sea. I look at pictures of houses for sale down there and some of them, even the cement and cinder block ones get really jacked up by the weather conditions. It's beautiful in the Caribbean, but the weather is rough. What Charlie says is true too...about the insects and mold.
- Q: would the three elements which make up cement ever come together to form cement naturally?
- There is no proof of cement occuring naturally.The chemistry of cement is very complex.The problem comes in the manufacture of the clinker. The raw mixture for cement is heated in a kiln to a temperature of about 1500 degree Celcius to produce clinkers and that is not possible in nature to regulate that temperature.This temperature has to be introduced wisely otherwise temperatures lower than this will produce cement of poor adhering quality and temperature higher than the required temperature might give glass instead of cement.Moreover, exposure to water decreases reactivity of cement.In nature this cannot be achieved due to rainfalls and moisture in air.
