The placement of steel reinforcing is dependent on the requirements of the strength and load-bearing of the concrete. A structural engineer should be contacted in this regard.
The standard length of rebars in the market typically ranges from 20 to 60 feet (approximately 6 to 18 meters), with 40 feet being a common length. However, manufacturers may also produce custom lengths to meet specific project requirements. In some regions, shorter lengths like 10 or 12 feet may also be available for smaller applications. It's important to check local standards and supplier offerings for precise options.
A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.
The best estimate of the square root of 5 is approximately 2.24. This value is derived from the fact that 2.2 squared is 4.84 and 2.3 squared is 5.29, placing the square root of 5 between these two values. A more precise approximation can be obtained using methods like the Babylonian method, which converges around 2.236.

rebars
The rule of overlapping rebars, also known as the lap splice length, dictates the minimum length that two reinforcing bars (rebars) must overlap to ensure effective load transfer between them. This overlap is typically specified as a multiple of the diameter of the rebar and is influenced by factors such as the type of steel, the concrete's strength, and the environmental conditions. Properly splicing rebars helps maintain structural integrity and prevents potential failure in concrete structures. Always refer to relevant codes and standards, like ACI or Eurocode, for specific requirements.

C 11 specification
There is no constant value for the ratio of the rebars and concrete volume. The rebars depends on the structural designer's safety factor and the factors affecting the framing like wind, earthquake and soil.
You can get an estimate by placing a call or going into the repair shop or auto body shop and requesting a rough estimate on the cost it would take to repair your car

The unit weight of 16 mm reinforcement is 1.58 kg/m
350x450mm with 12-16mm rebars on 5m span
Waist slab is used in case of stairs. The rebars are bent at some angles on which steps are built.
To determine the quantity of steel rebars in a raft foundation with a volume of 18,370 m³, a common approach is to consider the reinforcement ratio, which typically ranges from 0.5% to 2% of the concrete volume. For example, at a 1% reinforcement ratio, the quantity of steel rebars would be approximately 183.7 m³ (1% of 18,370 m³). However, the exact amount can vary based on design specifications and structural requirements. Always consult with a structural engineer for precise calculations.
