What are Advantage pre cast concrete slab than insitu concrete?
reinforced concrete prise
they give a goodstrength for concrete
allows the use of higher slump of concrete which results in stringer concrete
disadvantage: - require more time to construct compare to precast concrete slab -more on-site labor required - require formwork advantage: -most commonly use -do not require storage for material (e.g. precast concrete slab need place to store)
I think you are talking about embedding steel rods (rebars) in concrete, right? This would make the concrete much stronger. It is called reinforced concrete, and you can make all sorts of structures with it, something that you can't do with ordinary concrete. Though, I am not even sure anyone is using non-reinforced concrete nowadays.
One advantage of having a concrete floor would be for example the durability, Another benefit is for sure the fact that concrete is easy to maintain and that it is environmental-friendly. Besides that there a lot of different options regarding the possible design.
Quality control would be high on the list, for concrete may be made with minimum water under factory conditions. Concrete pipes for example are made from aggregate that appears only slightly damp! - But with steam curing, a quality product results. Accurate, repeatable products are another advantage. And factory manufacture produces the quality product at good speed. Freedom from weather and site conditions would be another.
Close packing and compression of aggregates for maximum rigidity and strength after curing.
An advantage of a concrete tetrapod is that it protects coastlines from waves. A disadvantage is that when they are used, it is hard to find a beach to go to where you can see the coast.
Examples of abstract, concrete noun combinations:Statue of Liberty (statue is a concrete noun; liberty of an abstract noun)science building (science is an abstract noun; building is a concrete noun)bargain basement (bargain is an abstract noun; basement is a concrete noun)the noun 'air' is a concrete noun as a word for the substance that surrounds the earth; the noun 'air' is an abstract noun as a word for the ambiance of a place.the noun 'heart' is a concrete noun as a word for an organ of the body; the noun 'heart' is an abstract noun as a word for the essence of something.the noun 'edge' is a concrete noun as a word for the sharp side of a blade; the noun 'edge' is an abstract noun as a word for an advantage.
because is needs the Ca-OH that is produced from the cement reaction with water to start the hardening but if you added Ca-OH to water it may be used a cement but its very expensive with no much difference in strength
