It could, but it should not crack. Either the grade was not prepared properly, the concrete was used too soon, the concrete was not reinforced, it was allowed to cure too quickly, or some other problem existed.
Reinforced concrete has reinforcing bars (called rebar) simply embedded in the pour. With prestressed concrete, reinforcing rods or cables are stretched (stressed) and then the concrete is poured around them. After the concrete hardens, the tension on the reinforcing members compresses the concrete, making it more resistant to failure where poor soil conditions or severe loads exist.Prestressed construction is usually done in-plant because of the equipment involved, and the completed assembly shipped to the site for installation.A similar method, called post-tension, is usually done on site, and involves the tensioning of reinforcing cables after the slab is poured, using a special hydraulic jack.
A precast concrete panel is: A panel, tile, counter, Fin, wall etc that is usually poured in a controlled manufacturing facility (although it can be poured on site) into a mold of a specific shape. Whether it is mass produced or a custom shape the precast panel is usually finished (sealed) before installation (although, again this also can be done on site). There are 2 ways to istall concrete products: Pour on site or precast and install. There are many pros and cons for each process. Which method to use depends on what the customer/architect/designer/engineer is trying to accomplish.
Fiberglass tanks are a later development to the traditional concrete tanks, and many people now see them as a superior product. They are much lighter so transporting them to your location is simpler and being lighter weight means it will take less effort to install. Despite being lighter, fiber glass is actually stronger than concrete and because there are no pores in fiberglass it means that they are not prone to attack by sewer gases that can cause the concrete tanks to deteriorate. This means a fiberglass tank should last longer than a concrete tank.
Special functions of concrete:It is used in building residential houses, apartments,etc.,It is used in precast elements.It is used in underwater constructionIt is used to construct infrastructures.
You should be able to pour an additional 3" over the new section. It wouldn't hurt to coat the existing with a bonding agent, after "keying" the surface by roughening it so that the new slab grips onto the old. First check whether these was a reason for the slab being laid at that level. Is it to do with the moisture barrier of the new slab? Slabs that do not have moisture barriers are often set below those that do to reduce the chance of moisture entering the dryer slab. If the slab level is a mistake then any contractor who poured it should be liable to pour a topping slab to bring it the correct height.
actually a gas can be contained in a container, basicly being poured, so plasma can be poured. YES
Most manufacturers of concrete stains recommend that one waits approximately 90 days after the concrete is poured. Check the instructions on the can of stain and follow the instructions and time frames accordingly.
Gasoline being poured into a tank is not a chemical change.

Masonry implies bricks, blocks, or stones held together with mortar. Bricks are fired ceramic. Blocks are usually formed concrete. And stones are formed naturally and quarried from the earth. They are held together with mortar. Concrete is used as mortar, but concrete can also be poured to make slabs and foundations. I think the difference is that concrete can be used by itself without being considered masonry. For example, even statues can be made from concrete by pouring them into a mold.
There are several advantages to strip foundation. They include being a proven method that the majority of builders know how to use it is easy for keeping the bricklayer occupied, it is fairly cheap, mistakes are too pricy to rectify after concrete has been poured, and services usually do not need immediate attention since they usually cross over the concrete.

no
In larger concrete projects with a good quality control program, a pour card is a document that describes the location of the concrete being poured, type/specification of concrete being supplied, a signature block by the inspector and/or engineer indicating that the rebar has been inspected in-place and approved, date of pour, serial number of the concrete truck(s) supplying the concrete, sign-off by the inspector indicating on-site tests for slump and air entrainment (if required) have been completed. Temperature, weather and ticket info from the concrete batch plant/delivery truck are also recorded. The contractor's quality assurance manager will typically keep all the pour cards for a project on file, especially in the even that subsequent testing indicates substandard concrete was installed.
Yes it is
