RCC is Reinforced Cement Concrete. PCC is Plain Cement Concrete. The main difference is that PCC has no reinforcement in it.
In construction RCC means reinforced cement concrete, however RCC Pardi is a versatile and hardy roofing material. Yes, it is composed of reinforced cement concrete. The reinforcement is typically steel.
To prevent from the corrosion of steel...
in engineering a factor of safety is accounted. The reinforcement should be say four times stronger to meet the load so its necessary to evaluate the probable load which includes it's self weight. The design feature will have an impact with quality of reinforcement
Rebar detailing is the arrangement of the reinforcing steel in the the concrete structure. it shows the details of the shape, size, number or spacing of bars in any rcc structre. different sections of the structure is taken and the arrangement of the reinforcement is shown in it. the picture below is the detailing of rcc structre
It is in the stair-waist from the bottom with min. covering of 15 mm. or equal to the dia. of the main reinforcement (whichever is greater). The main bars are perpendicular to the treads and risers the distribution bars are perpendicular to the main bars and are above it.
RCC
It is one and the same thing according to IS 456-2000
It is the length of the main bar provided at the column beam junction or column footing junction to allow for the development of stresses to its design strength.
Stab column is the one which does not have footing and pedestal support(reinforcement), which it rises from beams or slabs for upper levels.- K @ $ !civil engineering - GITAM UNIVERSITY
it is the clear cover for stirrups. effective cover of the reinforcement = nominal cover+ diameter of stirrups+half diameter of main bars
