- Q:What are your opinions of fiber cement siding?
- ive been selling hardieplank and other cement sidings for ages and as far as im concerned they are the best siding option out there. not sure what vinyl costs but cement sidings go for about 90 cents.sqft here in CA probably less elsewhere. once its up its up and little to no maintenance and a 25yr guarantee.
- Q:Will watering new cement help it to cure?
- Avoid building on it for at least 4 to 10 days, depending on thickness. Concrete in industrial applications is deemed to have reached a high percentage of its final strength after 28 days, which is when it is tested. In reality, concrete continues to cure and harden for years!
- Q:why must you use cement board under ceramic tile?
- You use hardibacker because it will not expand and shrink like plywood and thus your tile will not crack. It will not retain the moisture that wood does and the mortar bed for the tile will adhere better. It also gives support to the tile and floor in that it will not flex when you walk over it as opposed to plywood. However, even with the use of hardibacker you still have to have a good sub floor under it...usually 3/4 plywood. The hardiback comes in different thicknesses as well and depending on your sub floor this will determine the thickness of hardibacker. Unless you have a concrete floor and then you can apply the tile directly to it...if it is level Go to Lowes and talk with the flooring people....they can walk you through it and there are pamphlets that show you what to do. good luck

- Q:I individual industrial and commercial households, is the general taxpayer, the scope of business is a hardware building, into the tickets are cement, out of building materials or materials can be it?
- Second, the purchase and sale business is also a category of value-added tax, the main should pay attention to the contract with the customer how to agree, such as the installation can be installed separately with the equipment sales, should issue a special invoice and installation invoices, and offset the purchase of equipment input tax If it is inseparable from the Inland Revenue Department, it is determined that this act is a mixed sale or a business tax Generally, the tax department has a certain proportion to approve it For example, , Sales part of the price in the total price of a certain percentage, is 30%, 50%, 70% I do not know, because I am not this line, hehe Finally, since it has been recognized as a general taxpayer, the tax device you do not have to install or do not close the tax bureau, they are in accordance with the requirements of the general taxpayer to look at you, on the basis of the above two problems, It is not a problem
- Q:What makes cement concrete 'rock solid'?
- When you mix Portland Cement, sand, gravel, water, and in some cases, an entraining agent, the mixture undergoes a chemical reaction due to the cement called hydration. This mixture hardens into what is called concrete. Gravel and sand in the concrete are what are called aggregates. The cement is what binds the sand and the gravel together. The gravel and the sand are what give the concrete its compressive strength (sometimes you add prestressed steel to give it better strength). If you simply used Portland Cement, it would fall apart easily. The sand is present to fill the voids, or empty spaces, between the gravel rocks. An entraining agent is often added (a liquid poured from a bottle) to remove the air from the mixture, resulting in a higher quality concrete.
- Q:Could desert soil be used to make marine cement?
- Caliche is a hardened desert soil (rock) that is typically near the surface. I would think that you would end up digging a lot of desert to get much carbonates. There would be a large amount of heavy equipment use, lots of dust, and lots of lost habitat. Typically cement is produced by exposures of limestone that are ground down and converted to cement. I would think this would generally be a more economical and more environmentally friendly option. Since you apparently have a chemistry background, you may already know this, but cement is generally made by taking calcite or dolomite and heating it up to create lime / cement. This has been done since the Roman Empire. I have never heard of bubbling CO2 in calcium and magnesium carbonates. Are you suggesting that bubbling CO2 in ocean water will precipitate calcite? I think it would probably have the opposite effect and create more acidity which would tend to dissolve carbonates. Note: Ocean water is very basic. It is far from acidic and will almost certainly never become acidic. If you add a base to the desert soil, form a pile on the ocean floor, and bubble CO2 into it, you might precipitate some CO2 if the water is warm enough IMO. It would probably make more sense in most instances to simply use regular cement which is designed to form a very solid and strong structure. Carbonates will precipitate out of sea water in warm shallow water. Some of the beaches of the Bahamas are formed from precipitated carbonates called oolites.
- Q:Cement - renewable materials?
- I would have to say C but B is also attractive. I could make the case that the rock that is used for cement is the result of hundreds of thousands of years in geologic processes. The energy spent to produce the cement is used. However, I could say that cement is very reusable. Old cement can be ground up and reused quite readily. sorry but the question is quite open ended. That is unless your teacher specified an answer in class and you just didn't catch it!
- Q:OUTDOOR TRASH CAN CEMENTED INTO GROUND.?
- Hello It depends on its location the 50's not all areas had proper drainage or water supplies so maybe a well for water supply or a soak away for drainage as regards removal if want to remove intact you will need to break up the surrounding cement best way to do this to avoid damage would be to hire or borrow a Kango style demolition Hammer SDS Plus, they are relatively light weight and with the high vibration impacting movement you are less likely to damage the stone artifact, once surrounding cement removed you can try levering up with some scaffold poles or set up an A frame over the top and use a block and tackle to lift out, if however you want to just break up and remove take a 14 lb sledge hammer to it and cement over. Good Luck Regards Alan
- Q:What percent of garnet is in cement?
- There shouldn't be any garnet in cement. Portland cement (the most common one) is a mixture of roasted limestone, clay and gypsum. None of these rocks normally contain garnets.
