as every size bar differ in diameter and possibly type, the reinforcement steel is measured in kilograms per meter, say 8.5kg/m.
the steel weight is actually calculated, as a % of the cross-sectional area.
different applications have different minimum % steel required, roughly work on 1%.
the sum of the bars cross sectional area at each support and spans are seperately calculated and compared to the cross sectional area of the concrete, hence expressed as a %.

What is the Weight capacity for reinforced concrete floors?
Reinforced concrete floors can be designed for a wide range of loads. Different thicknesses and shapes of concrete and arrangements of reinforcing will have different strengths.
How many sand water and cement goes in the concrete mix?
sand=2*Weight of Cement water=cement/2
How much weight can reinforced concrete hold?
The weight that reinforced concrete can hold depends on various factors, including its mix composition, dimensions, and the quality of the reinforcement used. Generally, reinforced concrete can have compressive strengths ranging from about 20 MPa (megapascals) to over 40 MPa, meaning it can support significant loads, often exceeding several tons per square meter. For specific applications, structural engineers calculate load capacities based on design specifications and safety factors to ensure safety and performance.
How do you calculate the wastage in concrete?
You need to calculate the total volume of the space that the concrete has to fill. if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area and divide by 81 to get the number of yard needed.
Why is reinforced concrete better than normall concrete?
reinforced concrete is better than unreinforced concrete for one major reason. concrete is an extremely strong material when it is put under pressure. however, when tension forces are introduced it will tend to fail without reinforcement. short answer: unreinforced concrete will handle a lot of weight, but it is very brittle. source: carpenter

Does a 60 pound bag of cement weigh 60 pounds when dried concrete?
No, a 60 pound bag of cement does not weigh the same when it is turned into dried concrete. Once mixed with water and set, the weight of the dried concrete will be slightly more than the original weight of the bag of cement due to the water and other additives in the mixture.
What are the advantages and disadvantages of rcc frame structure?
Reinforced Cement Concrete or ñRCCî is cement concrete that is reinforced with steel bars, plates or mesh to increase the weight capacity of the structure. The advantages of RCC construction are: the materials used are easily available, the structures are durable, and it is fire resistant and is pest safe. The disadvantages include: there is no scrap value, constant checking is required and skilled labor is needed it the construction of the structures.
How many sand water and cement goes in the concrete mix?

Weight of reinforced concrete?
The weight of reinforced concrete varies depending upon the mix type. The engineering industry typically assumes a weight of 145 pounds per cubic foot (pcf) and most often uses 150 pcf for structural calculations. Note that this is for standard cured reinforced concrete. Lightweight concrete is generally taken as 110 to 120 pcf, again, depending upon the mix design. The fact that there is sometimes more or less steel reinforcement within the structural member is ignored.

How much does a yard of concrete weigh?
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.

Why it is called a biaxial voided slab?
Voided biaxial slabs are reinforced concrete slabs in which voids reduce the amount of concrete.While concrete has been used for thousands of years, the use of reinforced concrete is a relatively recent invention, usually attributed to Joseph-Louis Lambot in 1848. Joseph Monier, a French gardener, patented a design for reinforced garden tubs in 1868, and later patented reinforced concrete beams and posts for railway and road guardrails.The main obstacle with concrete constructions, in case of horizontal slabs, is the high weight, which limits the span. For this reason major developments of reinforced concrete have focused on enhancing the span, either by reducing the weight or overcoming concrete's natural weakness in tension
