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.

- its bad, you should be using a face mask, it can cause a disease called silicoses, and it works on your lungs over time like cement hardens. look it up.
- Q:why has the price of portland cement increased from 2007 to now?
- The manufacture of Portland cement is an energy consuming process that converts CaCO3 to CaO and reacts it with other raw materials . Portland cement clinker is made by heating, in a kiln, a homogeneous mixture of raw materials to a calcining temperature, which is about 1450 °C for modern cements. This requires a lot of energy , which is probably obtained from oil. Seen the price rise of oil since 2007 , This is reflected in the increased price of cement . Also other greenhousetaxes - consider how much CO2 is released in cement manufacture. Result - the price of cement has risen steeply.
- Q:how do you resurface cement steps?
- First check the quality of the cement, it may be inferior to construction standards. When you determine it is good, then you need to rough up the surface with a tool like a chisel to give the new surface a grip. Mix a screened sand with some portland at a 2 to 1 mix and trowel it on with a steel finishing trowel
- 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: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:The bottle on elmers rubber cement has a warning not to use if pregnant or contemplating being pregnant, and I am 5 weeks, what could the side effects be? I used it for aprox a half hour of time.
- The fumes are toxic and dangerous to anyone, and can cause brain damage. In pregnancy, inhaling toxic substances can be dangerous to the fetus. The chemicals are absorbed through the blood vessels in your nose, and then go through your blood to the placenta, and then into your baby's bloodstream. In general, pregnant women are advised to avoid harsh, strong smelling chemicals. Many can cause birth defects. It would probably take more than just a short exposure, but who knows? Why take the chance?
- Q:Im in the middle of planning to build a deck I'm my backyard and was looking through materials and noticed that concrete and cement were listed differently and that concrete was twice as expensive as cement. I'd always thought they were the same so I was just wondering what the differences were and how they work differently.
- Cement is the binder that you use with sand and aggregate to make concrete, or with sand (and sometimes lime) to make mortar. Most usual is Ordinary Portland Cement which has nothing to do with Portland Stone apart from a passing resemblence in colour. Cement is rarely used on its own as it crumbles very easily but when combined with other materials it becomes very strong. Many people make their mix too rich on the basis if a little is good, more is better. It isn't and is a common cause of failure so mix accurately and always use clean water. The set is a chemical (irreversible) one and generates heat. It is only any good in compression though, if you need it to span any distance you need to include steel or other reinforcement in it to give it tensile strength.
- Q:is it possible to make my pvc cement quot;normalquot; again... because now its all dry...
- I am assuming your talking about it drying in the can. If that's what happened then there is no way to bring it back. just throw it away and get a new can at the hardware store, walmart, or any lumber store. It is only a few $$
- Q:Preferably in a bright white color.
- Glue or concrete?
- Q:include social, environment and economical factors
- social: Not always the most attractive looking material. Some concretes and cements create a gloomy and depressing atmosphere. Environmental: Concrete and cement release green house gases. Concrete/cement footpaths over up natural soils and leave less room for trees to be planted and less natural earth for insects to live in. Economic: Expensive to remove and dump. In some cases, some cement foundations are so deep they are impossible to remove, meaning the land they're on cannot be used for much else, decreasing the land resources in the economy
