The cover required is a function of the serviceability required for the building, meaning if you need longer fire protection then the cove becomes more... at the moment i don't know the calculations(still studying) but the minimum cover is 25mm(acording to the South African code) or 1inch Also at coastal regions the cover should be more to prevent rust of the steel

What is the minimum and maximum allowable percentage of reinforcement steel in concrete?
The amount of steel required in concrete as reinforcement is measured using a formula that calculates the amount of pressure that will be put on the concrete. There are different formulas to identify the minimum and the maximum amount of needed steel, depending on if you are making a beam, slab, or column.
How many steel required for 1cum concrete?
Q1
Is priming of steel in concrete required?
No. A little surface rust will not affect the performance of the steel.
What is the maximum overlap of steel rods in reinforced concrete sections?
Steel reinforcing rods have minimum overlap requirements to ensure that the reinforcing has a continuous effect throughout the structure.In some instances this minimum overlap is 600mm, but the requirement does vary and must be confirmed by an Engineer for each particular design.Maximum overlaps would be used to ensure wastage is reduced, and to ensure adequate concrete cover.
How can you calculate for 1 cubic concrete steel requirement for slab?
well , reinforcement steel required for slab is nearly 0.7 to 0.8% of the volume of concrete so if concrete is 1 cum then steel will be 1*0.7/100 =0.007 but density of steel is 7850 kg/ cum so 0.007*7850=54.95 say 55 kg per cum so steel required to reinforce 1 cum concrete for slab is approximately 55 kgs.

Percentage of steel in RCC is about 1-2%.

How much steel is required for 1m3 concrete?
96kg steel bar is use in 1m3 but also depend on diameter of bar
Define steel reinforced concrete?
Steel reinforced concrete is concrete with rods of steel running through it.
What is reinforced concrete?
Reinforced concrete is concrete reinforced with steel bars because although concrete is very strong in compression (depending on its components) it is very weak in tension and the steel bars make up for the required tensile strength.
What kinds of materials are used to build highway bridges?
depends on the bridge type really. most are steel and concrete.
What is nominal cover in concrete?
Cover is the distance from the surface of the concrete to the surface of the reinforcement bar. Nominal cover (Cnom) is the cover that the designer, and steel fixer tries to achieve. Minimum cover (Cmin) is the absolute minimum cover that must be maintained for durability reasons after taking into account deviations in as built cover. Acceptable values of Cmin are given by BS8500 and EN 206. (Warning prior to BS8500, and EN206 minimum cover was also used as a term to describe nominal cover to the outer layer of bars). Δc is the cover tolerance. (Cnom must be >= Cmin + Δc) Note: bar bending/cutting tolerance for bars fitting between two fixed faces (defined in BS8666) is allowed for separately by reducing the scheduled dimensions of bars fitting between two fixed faces by +5mm (bending) +25mm (cutting) in the bar schedules.
What is the minimum of flate slab design?
Since most flat slabs contain reinforcing steel, the minimum would be the thickness required to cover the steel, generally 2" top and bottom. But the real answer depends on what the slab is supporting and the level of safety required. For a very general situation where the slab is supported on all sides and not significantly longer in one direction, a slab can be 6" wide and support light loading if properly reinforced.
