Q:Why is it that they make houses so simple in the US but in the Dominican Republic it's all cement?
as someone who has built a lot of houses on St Thomas let me add: availability. Wood 2x 4. 2x 8, 2x10 or whatever have to be shipped in. You can..and everyone has.....set up a block plant and a concrete plant on any island with gravel and sand.....and cement is easier to ship than lumber...... and as was said , TERMITES!!!! any lumber we use here has to be pressure treated with anti rot/anti bug chemicals or it wont last six months...
Q:1....80lb bag of cement?
2/3 cubic feet
Q:can i get my teeth whitened even though theres still cement?
You should probably go to your ortho and see about getting the rest of the cement removed. Dentists can probably also remove it, so you could ask your dentist if they can and then have them remove it. If your dentist can remove the cement and you're getting your teeth whitened by your dentist, you could probably have the cement removed and then get them whitened at the same appointment. You should call your dentist's office or ask at your next cleaning appointment about the cement and whitening your teeth. Who knows? Maybe if you call they might be able to get you in that day to get the cement removed. Hope I helped! :)
Q:how much does 1 cubic foot of portland cement weight in water?
portland cement has a density of 1506 kg/m³ 1 ft³ = 0.0283 m³ that is dry cement, not setup. You didn't specify if it is dry or setup. mass = 1506 kg/m³ x 0.0283 m³ = 42.6 kg The displaced water weighs: density of water at 20C = 0.998 g/cm³ = 998 kg/m³ 998 kg/m³ x 0.0283 m³ = 28.2 kg subtracting, we get 42.6–28.2 = 14.4 kg, or 31.7 lbs. .
Q:What is the best thing to write in wet cement?
This cement is now dry. or There is a dead body under here LOL Cheers from Australia
Q:Can I put cement on vinyl tiles?
You can cover the vinyl tiles, but you might end up with an uneven floor when you are done. Plus, like Doug said below, you will wind up with too much flexing for marble flooring, which might make it crack and fail much sooner than it should. You should probably bite the bullet, remove the tiles and start with a concrete slab.
Q:What cement stick to tile glue?
You should really try to get that glue up. The problem is going to be if it's like a mastic (soft and sticky) because that going to take a chemical stripper like Xylene or at least lacquer thinner. Go airflow and at least a half mask with chemical cartridges are necessary. A full mask and personal air supply is really a much better way to go. What ever you put down over that tile adhesive is only going to be as good as that tile adhesive. If you try to put down something hard and brittle like a thin layered cement (Sakrete's Top Bond) now you have something brittle over something soft what do you think is going to happen? You could try putting something soft over it like a urethane rubber but again if the old adhesive fails you spent a lot of time money on Urethane. If the heavy adhesive is off you can try renting a diamond grinder but you have to be careful these are not toys and you can do more damage than good if you don't think you can run it properly... Your cheapest way out may be to just put more tile down. If you like send my some pictures of the floor and I'll try to help... This is my profession.
Q:When is cement supposed to solidify?
You used way too much water and worked with it way too long. You can expect for it to crack, crumble and fall out of the holes rather soon.
Q:advantages and disadvantages of cement to people, or even the environment?
Q:how to calculate quantity of cement needed?
Simple LxWxH Length times width x height
