PORTLAND CEMENT

Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-specialty grout.

It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials.

Several types of Portland cement are available with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available.

Q:why cement board over hardie backer board when laying down a counter top for kitchen sink?: You don't. You use cement board (Durock) over 3/4 plywood if doing a tile top. There is no reason to use hardiboard under Durock. Hope this helps.

Q:What is the method of removing the cement on the tiles?: Do not use shovel shovel, but also easy to shovel Tile surface residual cement stains, can be used to remove the shield Wang Wang tile cleaning agent to remove, is specifically in addition to the surface of the cement tile residue, pour the solution, wait a few seconds, a wipe that is, clean, The tile surface has no negative effect Or you can use 1500 or 2000 water sand paper gently rub, you can also use dilute hydrochloric acid to wipe, wipe clean and then clean with water, should be able to erase Or building materials market is dedicated to clean up the tile cement Residual scavenger Tiles on the cement is not dealt with is very ugly, so when dealing with the use of some techniques to remove, to see which method is more appropriate

Q:I am putting tile on the wall in my bathroom (not in the shower), do i have to put cement board behind it?or can i just leave the drywall that is already there?: I think it has to be greenboard in a bathroom, check a tile installer or get a good book on it from the bookstore,

Q:What is the density of cement?: I will answer your question directly, then answer the question I think you are asking. Cement is a gray powder that is mixed with water and aggregate to make concrete. Cement and concrete are 2 different things. Cement is to concrete as flour is to cake. With that said, cement (the powder) has a specific gravity of 3.15, which means it's density is 3.15 times that of water. Water has a density of 62.4 pounds per cubic foot, so cement has a density of 196.6 pounds per cubic foot. If you actually mean concrete, which is the hard grey stuff, then it has a density of about 150 pounds per cubic foot. Hope that's what you were referring to.

Q:General taxpayer commerce company sales of cement, building materials products should be handed a few points: General taxpayer commerce company sales of cement, building materials products, applicable 17% VAT rate

Q:We intend to increase the strength of our pozzolan (from natural pozzolan) cement to 30MPa (28 days). But we could hardly reach it. What would the best thing to do?: There are two possible options. First you need to maximize the strength potential of the cement clinker you are blending with the natural pozzolan to make the pozzolanic cement. This means stabilizing the clinker mineralogy and boosting the alite content. You can do that by lifting LSF or SM dependent on your current clinker chemistry. Another alternative would be to add calcium fluoride to the raw mix. Secondly you could add a cement conditioner to activate the pozzolanic reaction in the cement. Possibly alkali carbonates or potassium sulphate.

Q:Cement. We all use it! Look out at your neighbourhood... Cement fences, pathways, houses!!! What is your opinion on another cement plant being built?: i guess it would be nice but i dont think it is possible.

Q:I unit expansion of production plants, machinery and equipment base, the purchase of steel, cement, building materials, such as the opening of the value-added tax invoices, whether deductible?

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:There is no mosaics cement in our country..... Advice me please: (A)For outdoor work the ideal adhesive to use is cement based. Either a cement based tile adhesive or a sand and cement mix. Of course the tile adhesive MUST be both water-proof and frost-proof. Cement base adhesives can be bought in bags from 2kg up to 22kg. They must be mixed to a firm consistency and applied to a dry surface. Your mosaic tiles are then pressed into the mortar to give a good contact. Work with a small amount at a time as you will normally have about 20 minutes working times with each batch. To help improve the flexibility and adhesive properties of the mortar add a plasticizer or polymer additive to the mix one part additive to two parts water. This is the preferred mix if you are making a mosaic for a predominantly wet location. Add this to the cement until the required consistency is reach. If using sand and cement mix use the ratio 3 or 4 parts fine sand to 1 part Portland cement. Mix thoroughly and add water. Mix to the required consistency. It is advisable to wear gloves whenever you are dealing with cement based products. To improve the adhesive and strength properties of the mortar, the setting time should ideally be long and slow. So if you can cover each days work with a polythene sheet to protect the work and help the setting.
