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.


CNBM Cement can be used for all types of architectural or structural concrete construction. Such application as pre-cast panels and systems, cast-in-place, masonry units, tilt-up panel systems, roofing tiles, terrazzo floors, highway median barriers, tile grout, swimming pools, stucco, culture stone,colored masonry products, cement paints and coatings, and ornamental precast concrete items.

Q:i.e. if a concrete slab is 10m3 how many bags of cement are needed?
I am going to assume you are not asking about ready-mix concrete since you seem to understand the difference between cement and concrete. Concrete is a mixture of water, cement, and aggregate. The amount of cement in this mixture usually runs anywhere from 10 to 15 percent. A good rule of thumb is 6 bags of cement per cubic yard of concrete. Since you are asking about cubic meters instead of cubic yards all I can say is a cubic yard is about .76 of a cubic meter, a rough guess would then be a little less than 8 bags per cubic meter. All of this is based on an 80 lb bag. On the off chance you are asking about ready-mix concrete, then an 80 lb bag yields about .6 cubic feet of concrete. you are going to need a large pile of bags, 45 per cubic yard. Good luck with that!
Q:placing 4 raw eggs in individual cut out egg carton, i space each egg at equal distance apart forming a rectangual shape. then i place a heavy cement block, about 30 pounds, carefully on the 4 eggs. the eggs are able to hold the block up, not breaking. how can this be possible? ned to know by this weekend. thanks
Its all about weight distribution. The spherical or dome shape of the egg shell helps distribute the weight through out the shell of the egg. You can expand this research by looking up dome shape buildings.
Q:There was a fire and the beam burned at the end that rest on the cement block. I want it to be solid when the new beam goes on.
You did not give much info on the cement block just the beam. How big of a block are we talking about? What is the construction of the cement block? 2,000 psi? 2500 psi? How intense was the fire? Most fires will not hurt cement blocks. How much weight is this beam holding? After you take the burnt beam off you can make a better assessment on the cement block. I'm willing to bet my last dollar, it will hold up a new beam fine. Good Luck!
Q:In general which of these three cements creates rocks that are the most resistant to weathering?
Iron oxide cement will colour the rock a distinctive rusty yellow-brown as a result of the significant presence of the minerals haematite and limonite. Calcite cement will leave the rock white but is soft, easily scratched by an iron nail and will fizz with the application of dilute hydrochloric acid. Silica cement will leave the rock glassy colourless, glassy white or rarely, a different colour but also glassy, it will resist being scratched by an iron nail, and will not react with dilute hydrochloric acid. The rock with the silica cement will be most resistant to weathering, and will normally remain as a positive relief feature around the surrounding rocks. The cement in the calcite cemented rock will tend to become dissolved away. The iron oxide cemented rock will be fairly soft but will resist erosion better than the rock with the calcite cement.
Q:what did egyptians use as cement to keep the big stones in place to make the pyramids?
None at all, I've been to the Pyramids in Cairo, the size of the blocks mean that cement or any type of bonding isn't needed.
Q:what is the man made cement made from ?
Portland cement is made from a select variety of rock, heated to about 1500 degrees c = 2732 f, then ground to a very fine powder. Concrete is made from cement, silica sand and gravel, sometimes reinforced with steel wire or rebar. Neil
Q:apparently fault breccia is a cataclasite, which are cemented rocks. However, my notes say that fault breccia consists of angular fragments set in an un-cemented matrix of wall-rock material.
Pressure is the key factor in the formation of a fault breccia. The term breccia is used to describe the coarser grained types. Much finer fault zone rocks are actually clay sized particles. These can be lithified by pressure (no cement). Mylonites would be an example. Perhaps the rocks in question are a combination of the two. (?)
Cement is a kind of light grey powder used in building houses, sidewalks, making building blocks, culverts and in some countries it' used to make roads. It's mixed with water using a shovel or it's mixed in a mixing truck if you need a large amount. Gravel, sand and the cement is all mixed together. There are also some type of glue that people call cement. Hope this helps.
Q:i buried my two parakeets in a white cement tomb (2 compartments for the 2 birds) Since white cement is.. cement, will the stench of their bodies decaying inside be also smelled from the outside? They're just interred so I still don't know what will happen- will i smell the odor or not? and when I touch the cement tomb, is stick to my hand as duslike powder so it quot;erodesquot; away. Anyway I can stop this erosion of the cement? Thanks to the one who can answer my problem :) Hope you understand my love for my pets to make them a white cement niche even if it sounds weird :)
You must love your pets very much to make them a nice place for burial. How do you feel about painting the tomb? If you paint the white cement tomb you will not smell any odor and it should stop the erosion of the cement. A good paint to try is Kilz. They have a line of paints and primers that offer superior coverage, mildew resistance and tough stain and odor blocking. I am sorry for your loss. I hope this helps.
Q:I know it's mostly different names for the same thing, but there must be some differences. It might have something to do with adding sand and/or rocks to make a mixture, but I'm not sure.
1 part cement + 3 parts sand = mortar. Add 3 parts grave and you have concrete. Depending on the type of construction you are doing.
