- Q:Was the gulf oil leak sealed with cement as stated, or was it concrete?
- In the oil industry it is known as cement. Granted, there are non-cement constituents, but there is no aggregate as the concrete that we're most familiar with has. The cement has to flow through small gaps and can't have rock chunks in it. The cement used in the oilfield also has a number of other additives to control such things as setting time and flow characteristics (called rheology).
- Q:Was there concrete/cement in the 1880s-1890s?
- Uh oh. She forgot the Romans in her History of concrete. Their concrete work is still standing. :) But I liked the story. I know you asked about the 1800's, but if you are also interested in Roman (cementitious) concrete history, here's an interesting site from the University of Santa Barbara: id-archserve.ucsb.edu/arthistory/...

- Q:What three substances are mixed with cement to make concrete?
- Sand, Gravel and Water
- Q:Is a Cemented or Uncemented Prosthesis Better?
- The response to this differs for various people. Because each person’s condition is exclusive, the physician and also you must weigh the pros and cons. Cemented substitutes tend to be more commonly used for older, less active people and individuals with weak bones, for example individuals who've brittle bones, while uncemented substitutes tend to be more commonly used for more youthful, more active people. Research has shown that cemented and uncemented prostheses have comparable rates of success. Studies also indicate that if you want one more hip replacement, or revision, the rates of success for cemented and uncemented prostheses are comparable. However, more lengthy-term data can be found in the U . s . States for stylish substitutes with cemented prostheses, because doctors have used them here because the late sixties, whereas uncemented prostheses weren't introduced before the late seventies. The main drawback to an uncemented prosthesis may be the extended recovery period. Since it requires a very long time for that natural bone to develop and fix towards the prosthesis, you aren't uncemented substitutes must limit activities for approximately 3 several weeks to safeguard the stylish joint. Also, it's more prevalent for somebody by having an uncemented prosthesis to see leg discomfort within the several weeks following a surgery, as the bone keeps growing in to the prosthesis.
- Q:Which is stronger PVC cement or Contact cement?
- Depends what you are using it on. PVC is designed to melt and weld two pieces of PVC. Contact cement won't work with PVC. Similarly contact cement is designed to laminate two surfaces like plastic or wood that will not be subjected to water or water pressure as found in an irrigation system fitted with PVC pipes. PVC cement will not work for that. Since you didn't indicate WHAT you are trying to bond, choose accordingly.
- Q:The front steps of our house were painted with a gray cement paint. I've tried all the chemical I've seen at Home Depot and nothing has worked. Any suggestions?
- try using a acid but leave it on to long and wear gloves thats how i got paint off our garage cement
- Q:how does sediment compact or cement into sedimentary rocks?
- Just speaking to sediments in general. Sediments become sedimentary rocks by one of two mechanisms -- cementation and compression. Cements “glue” one particle to another and commonly include: (1) calcite (CaCO3) (2) silica (SiO2) (3) limonite (Fe2O3) (4) hematite (Fe2O3.xH2O) Water flowing through certain sediments becomes supersaturated with calcite or silica. When this water evaporates, these dissolved minerals precipitate around the grains through which they flow. Over time, the precipitation of these cements overlaps, binding one grain to another. But the case of hematite and limonite cements is a little different. Iron occurs in solution in its ferrous (Fe+2) state. When ferrous iron encounters oxygen, it oxidizes into its ferric (Fe+3) state, which is insoluble. This ferric iron precipitates, coating the grains through which it flows with either hematite or limonite. It coats the grains, eventually binding one grain to the next. Sedimentary rocks commonly cemented include conglomerates, sandstones, evaporates, ironstones, as well as some limestones, some cherts, and some phosphorites. This process of cementation involves heat that allowed these fluids to exist and flow, but not so much as to cause a metamorphic rock to be created. Compression involves finer grained sediments. Clay, organic matter, lime mud, and phosphorite mud, once buried, are subjected to progressively more overburden. The thickness of these layers is significantly reduced as water is “squeezed” out. These fine particles have very high surface areas and surface charges causing these grains attach to one another. In addition, surface irregularities become intertwined, holding grains together. Sedimentary rocks that are formed from sediments by compression include shale and coal as well as some limestones, some cherts, and some phosphorites.
