- Q:The cement sealant I will be using is a LastiSeal brand. It is waterproof, non-toxic, and eco friendly. There is a15 year warranty on it, They say it can be used with koi ponds. So I think it will work for my newly laid cement pond wall. Just one thing. I have to wait 4 weeks for new cement to cure before applying the sealer to the cement. As long as the water is not touching the wall, can I keep water in the pond during these 4 weeks if need be?
- Cement pond is what the Beverly Hillbillies called their swimming pool. :) Concrete/mortar cures in the air or underwater so it wouldn't matter if water was in the pond or if it touched the wall. However, the coating you want to use may require it to be dry. Also, the strength of the concrete is related to how well it is cured, so don't load it up w/water too soon.
- Q:What type/brand of contact cement is the best (best being the strongest) for 1quot; schedule 80 PVC pipe? The PVC pipe will be under a high amount of pressure, And from what I have read on-line the fittings are the most common to fail under high pressure. So I would like to get the strongest glue made so I don't have to worry with it for a few years. Also Im looking for tips on how to prep and glue the fittings for the strongest hold possible. Thanks for your time!

- Q:what're the important characterisitcs that is detrimental to the cement quality? is there a makeshift procedure/method that can be used instead to test for such characteristics?
- depends on what purpose you require the cement for.. slump test determines the workability (should be) there is also the cube test to test the strength of concrete. when your talking about cement i assume the cement powder right? There are many many test, depending on which aspect you want to test, and wheter you want a destructive or non-destructive test. you can email me if you want to know more.
- Q:Please let me know the top four quality brands of cement that may be used in building /house construction.
- To answer your question it would be necessary to know in what area of the US you are located. The top four brands in the Mid West may not even be available on the east or west coasts. Although cement plants may be large in an area they quite possibly are not nation wide suppliers. As in business and housing most important is location, location, location. Check with a local concrete supplier and they will be able to provide an answer to your question. As a result of having to produce quality and consistent concrete the concrete suppliers typically use the top quality cement available in the area. But they usually limit their brand selection to one supplier, otherwise they would experience variations in quality of their concrete solely a result of the cement supplier. I provide to previous so you are not disappointed in only getting one quality brand in your area.
- Q:ingredients of cement?
- Hi, Cement is a fine, soft, powdery-type substance. It is made from a mixture of elements that are found in natural materials such as limestone, clay, sand and/or shale. Four essential elements are needed to make cement. They are Calcium, Silicon, Aluminum and Iron. Calcium (which is the main ingredient) can be obtained from limestone, whereas silicon can be obtained from sand and/or clay. Aluminum and iron can be extracted from bauxite and iron ore, and only small amounts are needed. Cement is usually gray. White cement can also be found but it is usually more expensive than gray cement. Cement mixed with water, sand and gravel, forms concrete. Cement mixed with water and sand, forms cement plaster. Cement mixed with water, lime and sand, forms mortar.
- Q:What three substances are mixed with cement to make concrete?
- sand and gravel for the cement to adhere or fix to, and water to make them mix. if iron or steel rods are put in the middle to provide additional strength, then it is called reinforced concrete. without sand or gravel, cement turns hard and brittle, kinda like chalk.
- Q:My parents have a family of life size cement deer that they want me to bronze. They figured I could find instructions on the internet but so far I'm not having a lot of luck. Does anyone know of a resource that can help me out? (I'm used to painting ceramics but never a bronze finish before -- and never anything that big!)
- There are various paints that might be used. However cement can be a problem when it comes to paint,because it is acidic.There is process called acid washing or maybe it's acid staining a process for applying color to existing cement ,primarily floors, that you might look into. Google cement colorants, cement stains etc. Most of the information available on the net applies to industrial application,floor coloring ,architectural applications. Working with cement can be hard on the hands so use some rubber gloves.
- Q:ive just got my braces fitted today, and at the back of my mouth i have some cement to stop me biting hard and breaking my braces. The problem is i find this cement really uncomfortable. will the cement wear down a bit ? or i will i get used to it? please help x
- Both. I had braces years ago and it gets to a point where you don't even notice them anymore. If the problem continues just go back to the orthodontist and they should fix it.
