Cement when mixed with sufficient quantity of water,the compounds present in cement reacts with water to form a cementitious crystalline structure that adheres to the sand and aggregates.This helps in binding the mass together and increases its strength till it becomes very hard.This is called hardening of cement.
reached its final setting time
It is not rain forced but re-inforced cement concrete. It means the concrete after setting and hardening.
no..it will be in liquid state and after it reaches its settling time, concrete starts hardening and finally to solid state...
SettingSetting begins to occur after the concrete is mixed and even before pouring. The cement in the concrete begins to stiffen after mixed with water. The concrete is beginning to change from liquid form to solid form. During the setting process, the concrete does gain strength, which is the beginning of the hardening process. When the water ingredient is added to the concrete mix, the concrete is still pliable and flexible, sort of a paste. There is two stages of setting: initial and final setting. Initial setting is when the concrete loses it flexibility and begins to harden. Final setting is when the concrete can sustain some load, but still has some moisture within the mixture.HardeningHardening of the concrete is the stage when the mixture gains strength. The cement ingredient begins to attach itself to the aggregate as the water dries off the mixture. The hydration of water is what starts the hardening process. It generally takes five to seven days for the concrete to complete the hardening process. The easiest way to increase the strength of concrete is to add cement to the mixture. The more water used in the mixture, the weaker the concrete and it will also delay the hardening process. Once the concrete has hydrated all the water from the mixture, the hardening process is complete and the concrete is as strong as it will get.
Concrete
Setting indicate the beginning of stiffening of concrete ,in this case the concrete has not any strength and any cracks if occur can be re unit the concrete in this state just like a dough bread afar setting the concrete stiff and become hard and get strength and any cracks if happen cant be re unit

Concrete
It is heavy. After it dries, it is hard. Actually, drying is not directly linked to hardness in concrete. After concrete is poured, putting it in a wet environment by spraying it constantly with water will hasten its hardening and its curing. After concrete cures, it is hard.

Anchor bolts are used to secure items to concrete. They can be wet-set meaning inserted into the concrete while it is still hardening or the concrete can be drilled and the anchors set in to them.
Excess water (over hydration) causes weak concrete. The water in concrete is there to start a chemical process which results in the hardening process. The excess water is not used in the chemical process and results in a weakened concrete.
Formwork is used for the shaping of concrete structures to aid in the hardening phase of conrete.

mostly is the hardening done by induction hardening machine, I know also manufactures that do this using the flame hardening method.
