Q:Why does cement curl when you cut it with a saw sometimes?
I have never seen cement curl, possibly don't understand- sorry. As far as dryness. Concrete when poured starts to cure and set immediately. The outer edges cool or cure faster than the inside area because there is more sq inches exposed to the air. Sometime in the late evening go out barefoot and stand on a sidewalk that has been in the direct sunlight during the day. You will notice if you put your foot on the edge it is much cooler than the middle - same thing the edge has more surface and edge exposed to allow it to cool quicker. Sorry about the curling - I just didn't understand - my fault.
Q:Can you use Track spikes on cement?
No! that is a TERRIBLE idea! it will flat out ruin your spikes and kill your legs
Q:please tell me the order of increasing strength of cement mixtures?
cement or concrete. Cement is baked lime. Concrete is a mixture of sand gravel and cement. Fly ash is more of a lubricant and helps to give you a smoother finish. A basic mixture for concrete is 1 cement 2 gravel and 3 sand. To increase the basic strength add more cement as cement is the binder. To much cement and the result will be crumbly. The more sharp points in the type of sand or the more surface texture of the rock increases strength. reinforcement wire or bar will increase structure strength. Dan
Q:A cubic meter of concrete mix contains 420kilograms of cement,150 kg of stone and 120 kg of sand.?
150 Kg To Stone
Q:Looking for ideas on pouring a cement bartop?
Make bowls in the cement for pretzels. How about having people write things in it when its wet? Maybe set in different types of wood, like cherry. How about small holes at the ends that lead to garbage cans.
Q:Why don't famous people get burns when they make handprints in cement?
Ummm... you don't get burns when touching wet cement...
Q:CEMENT WAS POURED ON MY DRIVEWAY AND THEN IT RAINED 5 HOURS LATER?
it may effect the texture a bit but the cement should cure just fine despite the water. although the cure time will increase based on how much water was absorbed.
Q:Horse limping on cement?
Discounting all other injuries, it sounds like he has an abcess. You need to let him rest - no riding - if that is the case - until the event is over. As far as determining an abcess, most people (farriers and vets) will use hoof testers to make their diagnosis. My opinion, it is useless and it really hurts your horse. If all else is ruled out and it is an abcess, your horse needs to be turned out and let him move around as he can normally. This really hurts. Watch your horse everyday. Usually within a few days, the abcess will pop out either at the coronary band or on the bottom of the foot. After it pops and begins to drain, you should soak the foot in warm water and epsom salts a couple of times per day for about 20 minutes. This will help draw out the infection and help it dry out and it will really feel good to your horse's foot. If it pops on the bottom, it is usually recommended that the abcess be packed and wrapped to keep it clean and the bandages changed at least twice daily. Again, you should not ride your horse until he gets over this. It is really painful. Usually, bute is recommended for a few days to help the horse cope. When the abcess pops out, this releases the pressure and he gets a lot of relief. If he were my horse, I would pull his shoes at least while he is healing. Abcesses can be produced by bruising or some kind of blow to the foot but you are at increased risk when you are consistently putting nail holes in the hoof wall every few weeks. The holes open the pathway for bacteria and other antigens to enter. It is just another reason why barefoot is better. So sorry your boy is hurting. Help him. good luck.
Q:How do you do the seams on cement backer board?
Backer Board Lowes
Q:installing cement board/hardibacker?
Don't place it over the lip. Your cement board, or greenboard for that matter, should rest on top of the lip. Then you fill in the gap with thinset and mesh tape. That way the wall doesn't bulge out at the bottom on all three sides making the tiling harder to do.
