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: Home built in the late 1800's. The old house requires repainting every couple of years. The paint has an alligator appearance - very thick, chippy and crackled. Am considering re-siding with fiber board siding rather than vinyl. Is it possible to install the cement siding boards over the existing wood boards or would they need to be removed? Also - I know that when installing vinyl siding, they cut off the sill boards and crown molding around windows/doors. I would prefer to preserve the architectural interest of the home as much as possible. Is the cement siding option kinder to the window and door details then vinyl siding?
- I recommend you talk to a siding contractor and have him give you advice to use yourself or for bidding the job out.
- Q: Can a grenade blow through brick/cement wall?
- it can but I guess it depends on how strong the grenade is but from the movies I've seen..it can
- Q: is contact cement the same as rubber cement? If not what is the difference and is contact cement a coadhesive?
- They are the same in that they are both adhesives, that's about as far as it goes. Rubber cement is used for a variety of applications, a number of which are temporary, it behaves as though it is a liquid rubber, it will stretch, remains flexible and is water resistant. contact cement is usually permanent, it can be released with the use of a solvent, an example of contact cement is the laminate applied to counter tops, commonly referred to as Formica. You apply a thin coat of the adhesive to both surfaces to be bonded. let it dry to the touch, then position the two pieces, usually with separation sticks placed between the two, you start removing them one at a time from the center or one edge, as you remove them you apply pressure to the two pieces as they touch, when all sticks have been removed you roll the two with a hand roller to bond them, at that point you do not separate the two without a solvent, there is no moving the piece around to position, when they touch they stick, that's it
- 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!
- I like Oatey brand Regular clear Advanced cement for PVC. Use a PVC primer first which is usually purple let dry then using the applicator supplied in the can of cement apply a thin even layer to the outside of the pipe and then to the inside of the fitting. Working time is around 30-45 seconds. Insert the pipe into the fitting than give it a half turn. Using excessive amounts of cement is not better. The even layer you have applied will be evenly distributed with the turn of the fitting. GL
- Q: refinish stain and seal a cement floor?
- if you are happy with the color after sanding them you dont need to stain them. you can just apply the varnish. if you want to change the color, and you might because they tend to look very light after sanding then you have the chance to pick the right shade of wood you want. plus after the sanding all the hard work is done. I would stain them just so the color is even.
- Q: They just put it on me, it worked just fine, then it came off on command without a trace (back in the 80's.) But I'm wondering what it chemically actually is.
- It's called, simply enough, dental cement, but chemically, it's usually zinc phosphate. Sometimes the zinc phosphate is mixed with polyacrylic acid, creating polycarboxylate cement. and in response to the additional detail: I don't know how the zinc phosphate cement is removed, but for the carboxylate, they use organic acids (especially citric, I think).
- Q: history of the development of cement?
- a combination of hydrated non-hydraulic lime and a pozzolan produces a hydraulic mixture (see also: Pozzolanic reaction), but concrete made from such mixtures was first used by the Ancient Macedonians[1][2] and three centuries later on a large scale by Roman engineers.[3] They used both natural pozzolans (trass or pumice) and artificial pozzolans (ground brick or pottery) in these concretes. Many excellent examples of structures made from these concretes are still standing, notably the huge monolithic dome of the Pantheon in Rome and the massive Baths of Caracalla.[4] The vast system of Roman aqueducts also made extensive use of hydraulic cement.[5] Although any preservation of this knowledge in literary sources from the Middle Ages is unknown, medieval masons and some military engineers maintained an active tradition of using hydraulic cement in structures such as canals, fortresses, harbors, and shipbuilding facilities.[6][7] The technical knowledge of making hydraulic cement was later formalized by French and British engineers in the 18th century.[6]

- Q: i used cement to seal large gaps in the house, but in an upside down suface where i used lots of it on, touching it makes parts of the surface turn into powder and chunks fall off. I did it rudimentary with my hands and a smoothed it as best as i could then but still looks and feels messy. The holes are filled and its solid, the surface though is powdery.
- Cement never sets up properly when you play with it with your hands like it's clay. If you ever watched a mason, they never play with it like that. then too, you probably made the mix too thin and that causes it to set up even slower. You really should have got a pro to do it...please do it the next time, which will not be very long. Papaw
