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:in case of setting and hardening of cement, the first thing is stiffening
- its the initial stage of the cement setting up after it has been hydrated.
- Q:How long should I let new cement cure before I can build on it?
- 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:We are creating cement test samples in construction materials class and our group is to use a .55 water/cement ratio. Our test cylinder is 4quot; diameter by 8quot; height. I know that this is 0.058 ft?. I am having trouble trying to figure out a formula that i can figure out how much water/cement/aggregate that i should put in this cylinder in order to make 0.058 ft?.
- First you need to determine the specific density of the cement usually 3100kg/m3. The aggregate and sand will be about 2600kg/m3. Next determine the ratio of cement to fine aggregate (sand) to coarse aggregate. A fairly low strength concrete would have a ratio by weight of 1:2:4. The density of the finished concrete will be about 2400kg/m3. So start with 100kg of OPC (Ordinary Portland Cement) then fine aggregate is 200kg and coarse aggregate is 400kg. The water is 55kg (0.55 w/c ratio). Add up total weight and obtain volume by using overall density of mixture (2600kg/m3). This volume is called the yield. By using the ratio of the quantity that you require against the yield using 100kg of OPC you can calculate the amount of OPC, sand, Aggregate and water that you need.
- Q:Has a body ever been found with cement shoes?
- I don't think I've ever heard of one being found .... but here's my thoughts on it. If you're dumping a body with cement shoes you wouldn't want to be close enough for them to find it. And if you do sink a body you'd be hoping that the sharks and flesh eaters would tear the body apart making it difficult to find a body intact. So maybe on the bottom of the ocean is a cement container with some feet in them. But perhaps after a while the sand goes over the container and no one pays attention to it and the bones come apart and get tossed out of the container anyway so the evidence of the body in cement shoes is no longer apparent. I'm not saying any of this is true but .... who knows for sure!
- Q:hi, I was wondering if anyone could suggest an adhesive more permanent than rubber cement. I am making a package and wanted to glue something onto the package for a friend. also, is there a difference in the level of adhesive-ness between rubber and paper cement? also, what's the difference between the one coat and two coat rubber cement?thanks in advanced,craftgoth420
- It depends on what the surfaces are, and their flatness. If it is a paper package, hot melt or Gorilla Glue. If the package is going through the mail or a courier service, put the item into the package.
- Q:know the cement but I want to know the exact definition in engineering view.?
- cement is a cementing material or binding material used in engineering construction. It is manufactured from calcareous substance and is many respects to the strongly limes but possessing far greater hydraulic properties. thanks.
- Q:a small block of cement cost. Our driveway needs to be fixed, a 4x4 block has to be re poured.
- Look in your Yellow Pages under Cement,Transit Mix give them a call.The price where I live will be different than where you live.Try It. 10/10
- Q:So I got my spacers and brackets put on at the orthodontist next week they're putting in the wires and finishing all that. They put cement on 2 bottom molars so my brackets wont break and come intact. I cannot eat and I'm in pain. Will they remove this cement when I go get my wire put in? The cement doesnt let me eat and its not even. Should I tell my ortho, that its completely uncomfortable and painful? Please I need answers! Lol.
- the cement on the molars acts as a bite block so that your teeth dont touch eachother.this will help to put the brackets and faster movement of teeth will take place as the upper and lower teeth dont touch each other. once the initial alignment of teeth is done in 8-10 weeks,the cement will be removed. till then take soft diet like soup,noodles,pasta,milk,juices etc. pain will go away in 3-4 days time.
- Q:Why does wet cement have a strange odour?
- You really shouldn't sniff it! The odour is from the chemicals that go to produce the cement. Back in April 2008, an enforcement notice was served on Lafarge Cement at Dunbar after an investigation showed an offensive odour coming from the site. The Scottish Environment Protection Agency (SEPA) carried out the probe at the plant following complaints from members of the public about emissions. A SEPA spokesman said: The investigation showed that on at least three occasions since the beginning of March, Lafarge was in breach of the environmental licence as an offensive odour was present outside of the works due to the plume from the main stack (chimney) grounding prematurely downwind of the works.
- Q:what is the difference between (concrete) and (cement)?
- concrete-A strong hard building?material composed of sand and gravel and cement and water cement-A building?material that is a powder made of a mixture of calcined limestone and clay; used with water and sand or gravel to make concrete and mortar ergo,you can't create concrete without cement,but sometimes concrete pavement can be refered as cement.
