Normal weight concrete -- a mixture or sand, cement, and stone gravel -- has an accepted density of 145 pounds per cubic foot. Since there are 27 cubic feet per cubic yard, a cu.yd. weighs 3915 pounds, or almost two tons. Complicating your question is the word "reinforced." Reinforced concrete has steel bars in it, called rebar. Steel has a density of about 490 pounds per cubic foot, which is more than three times the density of concrete, so the generally accepted density of normally reinforced concrete is 150 pounds per cubic foot which results in a cubic yard weighing 4050 pounds, but this depends on the quantity and grade of the rebar used. (Ref. AISC Steel Construction Manual, 13th Ed. Page 17-24. Also older editions have this same information.) There is light weight concrete made with lighter weight substitutes such as vermiculite for the stone and sand. These can have weights from 85 pcf. Also, there are heavy weight concretes made with steel punchings or pieces of lead used to line rooms for x-ray machines or other radioactive sources. There is a Wikipedia article on rebar, if you're interested in looking it up.

Wet concrete weighs about 4,000 per cubic yard. Some types of concrete weigh more or less. Lightweight concrete weighs about 1,000 pounds less.
None. Concrete may be formed without metal.If you are reinforcing the concrete with rebar then it depends on what loads the reinforced concrete will have to bear, the dimension of the rebar, the safety factor involved, and lots of other geometric factors.Steel bars quantity will be according to structure element; but a (very) rough average of 120 KG per cubic meter.
negative in that, when all common factors are compared to those of REINFORCED concrete, it is much weaker and more birtle
Most bags will make a 1/3 of a cubic foot of concrete.

Approximately 2.0 tonnes/m3.
Fresh concrete can weight about 3700 lbs for every cubic yard. The density will also determine how much is its weight. assuming its weight to be around 150 lbs for per cubic feet. This would make it around 4000 lbs which could come to 2 tons. Calculating the weight of reinforced concrete could be a bit more difficult since this type come with steel bars. On an average, we could assume 500 lbs for steel density per cubic feet which is almost 3 times more than cement. So with this calculation, we can assume the weight of reinforced concrete to be around 4000 lbs.
Concrete is usually reinforced by adding steel. The cost of reinforcing concrete depends with the given area under which the steel is placed to reinforce it.
