1. RCC (Reinforced Cement Concrete)
CONSTRUCTION

2. TYPES OF BUILDING STRUCTURES:
1. LOAD BEARING STRUCTURE…..
 It has load bearing walls which receive the loads and transmit the
same to the ground though their foundation.
 230,345 mm thick walls are load
bearing walls.
 R.C.C. slab is provided directly
on load bearing walls.

3. 2. FRAMED STRUCTURE…..
 In the buildings with framed structure, load is transferred through a
frame of R.C.C slab, beam, column.
 In this type of structures, there are
partition walls of 115 mm thick,
which divide space.
 Construction time is less.

4. DESIGN LOADS / BUILDING LOAD….
TYPES OF LOADS…..
1. VERTICAL LOADS:
 Dead Load (Self Weight)
 Imposed Load (Live Load)
 Snow Load
1. HORIZONTAL LOADS:
• Earthquake Load (Seismic)
•
• Wind Load

5. Dead loads are those that are constant in magnitude and fixed in location
throughout the lifetime of the structure .
Dead lode comprises of the weight of all walls, partitions, floors and roof
including all other permanent construction in the building.
A. DEAD LOAD:
B. LIVE LOAD:
Live loads are those that are either fully or partially in place or not
present at all, may also change in location; the minimum live loads for
which the floors and roof of a building should be designed are usually
specified in building code that governs at the site of construction.
C. ENVIRONMENTAL LOAD:
Environmental Loads consist of wind, earthquake, and snow loads.
such as wind, earthquake, and snow loads.

6. INTRODUCTION:
What is the difference between RCC , PCC and DPC in construction…..?
RCC :
It is composite material contains CEMENT (acts as bonding agent), FINE
AGGREGATE (i.e. Sand, Which gives smooth finished surface) and coarse
aggregate (i.e. Crush, which gives strength) in addition of STEEL which
reinforced the material providing tensile strength. Used to construct
building structural members like beam slab column foundation.
PCC :
PCC is plain cement concrete. it is done to provide a hard and level surface
against the soft and undulation soil below the rcc foundation. It is same as
RCC but without steel.

7. DPC :
It is quite different than PCC and RCC... It is used for protecting the walls
and floor from water (damping) also from water logging and salinity.

8. CONCRETE FRAME STRUCTURES:
Concrete frame structures are a very common - or perhaps the most common-
type of modern building. As the name suggests, this type of building consists
of a frame or skeleton of concrete. Horizontal members of this frame are
called beams, and vertical members are called columns. Humans walk on flat
planes of concrete called slabs.

9. The concrete frame rests on foundations, which transfer the forces - from the
building and on the building - to the ground.

10. Shear Walls are important structural elements in high-rise buildings. Shear
walls are essentially very large columns - they could easily measure 400mm
thick by 3m long - making them appear like walls rather than columns. Their
function in a building is to help take care of horizontal forces on buildings like
wind and earthquake loads. These are usually not required in low-rise
structures.
Elevator Shafts are vertical
boxes in which the elevators
move up and down - normally
each elevator is enclosed in its
own concrete box. These shafts
are also very good structural
elements, helping to resist
horizontal loads, and also
carrying vertical loads.

13. SLAB

14. Raw Materials for RCC:
1. Cement
2. Coarse aggregate
3. Fine aggregate
4. M.S. Steel bar
5. Binding wire
6. Water
7. Shuttering materials such as wooden Ballies, Planks, and Iron Plates etc.
MATERIALS REQUIRED FOR RCC:

15. ADVANTAGES OF RCC:
•Reinforced concrete has a high compressive
strength compared to other building materials.
•Due to the provided reinforcement, reinforced
concrete can also withstand a good amount tensile
stress.
•Fire and weather resistance
•The reinforced concrete building system is more
durable than any other building system.
•reinforced concrete can be molded to any shape
required, it is widely used in precast structural
components.
•The maintenance cost of reinforced concrete is
very low.

16. ADVANTAGES OF RCC:
The maintenance cost of reinforced concrete is
very low.
In structure like footings, dams, piers etc.
reinforced concrete is the most economical
construction material.
It acts like a rigid member with minimum
deflection.
Compared to the use of steel in structure,
reinforced concrete requires less skilled labor
for the erection of structure.

17. RCC SPECIFICATIONS:
Shuttering shall be done using seasoned wooden boards of thickness not less
than 30mm.
Surface contact with concrete shall be free from adhering grout, nails, splits
and other defects.
All the joints are perfectly closed and lined up.
Nowadays timber shuttering is replaced by steel plates.
All the props of approved sizes are supported on double wedges and when
taken out, these wedges are eased and not knocked out.
All the framework is removed after 21 days of curing without any shocks or
vibrations.
All reinforcement bars conform IS specifications and are free from rust,
grease oil etc.
The materials proportion should be as per the specifications of the concrete.

18. VARIOUS RATIOS OF RCC:
RCC denotes Re-in forced Cement Concrete in which cement, sand and
aggregates are laid with the help of mild steel. This is most important part of
the structure. Generally 1:2:4 and 1:1.5: 3 ratios of RCC are used in
construction work.
RCC 1:2:4
Where cement concrete 1:2:4 is used; it means 1 part of cement 2 parts of
fine aggregate/coarse sand and 4 parts of coarse aggregate. This ratio of
cement concrete gives high strength of cement concrete and is recommended
for following works.
• For general RCC work in buildings
• Lintels
• Pavement etc.

19. VARIOUS RATIOS OF RCC:
RCC 1:1.5:3
Where cement concrete 1:1.5:3 is used; it means 1 part of cement 1..5 part of
fine aggregate/coarse sand and 3 parts of coarse aggregate. This ratio of
concrete also gives very high strength of cement concrete and is
recommended for following works.
• Structure carries in heavy loads
• Important RCC structure such as columns, beams, slabs, cantilever,
Chhajja, porch, and balcony etc.
• Minimize the effects of earth quake.
• Gives more strength accordingly if Tor or Ribbed steel is used with cement
concrete 1:1.5:3.

20. ONE WAY/ TWO WAY SLAB IN RCC:
One way slab is supported on two opposite side only thus structural action is
only at one direction.
ONE WAY SLAB

21. ONE WAY/ TWO WAY SLAB IN RCC:
ONE WAY SLAB
Two way slabs are the slabs that are supported on four sides and the ratio
of longer span (l) to shorter span (b) is less than 2. In two way slabs, load
will be carried in both the directions. So, main reinforcement is provided
in both direction for two way slabs.
