7. Excavation
Excavation Excavation is the process of moving earth, rock, or other materials with
tools, equipment, or explosives. It includes earthwork, trenching, wall shafts, tunneling,
and underground. Excavation has a number of important applications including
exploration, environmental restoration, mining, and construction.

10. PCC
The term PCC refers to plain cement concrete. The amalgamation of cement, fine aggregate,
and coarse aggregate are known as plain cement concrete (PCC). Before beginning R.C.C. or
masonry PCC is done to form an even surface and to avoid mixing with the soil and to avoid
soil extracting water PCC is used.
How does Concrete Plain Cement laying work?
You need to apply layers of the PCC that are no thicker than 150mm. The RCC is completely
vibrated using mechanical vibrators to produce dense concrete.
Perform hand compaction to make sure the concrete is equally pasted in the corners of the
structure.
A wooden tampering rod would ensure perfect corner walking and assist establish
consistency.
Manage the hand compaction and ensure sure it is finished before the initial selling phase
begins. This often occurs 30 minutes after adding water to the dry mixture.
You must be satisfied with my response on PCC full form in civil engineerin
11. PCC
PCC concrete: Properties
Strength
High compressive strength is required for the PCC.
Tensile and shear strengths should be between 8-12 % and 8-10 % of compressive strength,
respectively.
The following factors affect the PCC’s compressive strength:
Cement Content
Water Cement Ratio
Method of mixing, placing, compacting, and curing.
Quality of the materials used
Age of the concrete.

Workability
PCC should be very feasible.
Mixing, handling, and transporting it should be simple.
Bleeding and segregation should not be present.
Slump testing can be used to determine workability.
Fire Resistance
To avoid issues like burning, spalling of concrete, etc., PCC should be extremely fire
resistant.

14. RAFT
RAFT OR MAT FOUNDATIONS
A raft foundation, also called a mat foundation, is essentially a continuous
slab resting on the soil that extends over the entire footprint of the building,
thereby supporting the building and transferring its weight to the ground.
A raft foundation is often used when the soil is weak, as it distributes the
weight of the building over the entire area of the building, and not over
smaller zones (like individual footings) or at individual points (like pile
foundations). This reduces the stress on the soil.
The concept of stress is very basic to civil engineering. Stress is simply weight
divided by area. For example, if a building measuring 5 x 5 weighs 50 tons,
and has a raft foundation, then the stress on the soil is weight / area = 50/25
= 2 tons per square meter.
15. RAFT
If the same building were supported by say 4 individual footings, each of 1 x
1m, then the total area of the foundation would be 4 m2, and the stress on
the soil would be 50/16, which is about 12.5 tons per square meter. So
increasing the total area of the foundation can dramatically lower the stress
on the soil, which is nothing but weight per square meter.
A raft foundation is also very good for basements. Foundations are created by
excavating soil in order to find strong, compact, undisturbed natural soil that
is at least a few feet below ground level. This soil is much stronger than the
loose soil at the surface. If we construct a raft foundation at say 10 feet below
ground, and build concrete walls around the periphery, this makes an
excellent basement. Therefore, an engineer designing a building with a
basement will tend to choose a raft foundation over other types of
foundations.

17. Imposition of Loads
Loads must be transmitted to structural elements
Terms associated with imposition:
– Axial load
– Eccentric load
– Torsion load
18. Structural Elements
Buildings are an assembly of structural elements designed to
transfer loads to the earth
Can be defined simply as:
– Beams
– Columns
– Walls
– Connections
19. Beams
Transfers loads perpendicular to its length
Types of beams:
– Simple beam
– Continuous beam
– Cantilever beam
– Lintel
– Girder
– Joist
– Truss and Purlin
20. Columns
Any structural component that transmits a compressive force
parallel through its center
Typically support beams and other columns
Generally vertical supports of building
Can be vertical, horizontal, or diagonal
21. Walls
Really long, but slender, column
Two categories:
– Load-bearing walls
• Carries weight of beams, other walls, floors, roofs, other
structural elements
• Also carries weight of the wall itself
– Non-load-bearing walls
• Need only support its own weight
• Example: partition wall between two stores in a strip
mall
22. Connections
Weak link as it relates to structural failure during fires
– Often small, low-mass material that lacks capacity to
absorb heat
Three categories:
– Pinned
– Rigid
– Gravity

25. STEEL
What is Steel Reinforcement?
Steel reinforcement are steel bars that are provided in combination with plain
cement concrete to make it reinforced concrete. Hence these structures form
steel reinforced cement concrete structure (R.C.C). Steel reinforcement is
commonly called as ‘rebars’.Need for Steel Reinforcement
Plain concrete is weak in tension and strong in compression. Tensile property
for concrete structures is obtained by incorporating steel reinforcement. The
steel reinforcement is strong in both tension and compression. The tensile
property provided by the steel reinforcement will prevent and minimize
concrete cracks under tension loads. The coefficient of thermal expansion of
steel reinforcement and concrete are similar in that they undergo similar
expansions during temperature changes. This property will ensure that the
concrete is subjected to minimal stress during temperature variations.
26. STEEL
The surface of the steel reinforcement bars is patterned to have a proper
bond with the surrounding concrete material. The two main factors that
provide strength to the concrete structures are steel and concrete. The
design engineer will combine both the elements and design the structural
element such a way that the steel resists the induced tensile and shear force,
while the concrete takes up the compressive forces.Types of Steel
Reinforcement
The steel reinforcement used in concrete construction is mainly of 4 types.
They are:
1.Hot Rolled Deformed Steel Bars
2.Cold Worked Steel Bars
3.Mild Steel Plain Bars
4.Prestressing Steel Bars
27. SLAB
Slabs
Slab is an important structural element which is constructed to create flat and
useful surfaces such as floors, roofs, and ceilings. It is a horizontal structural
component, with top and bottom surfaces parallel or near so. To read more
about slab thickness evaluation please click here . Commonly, slabs are
supported by beams, columns (concrete or steel), walls, or the ground. The
depth of a concrete slab floor is very small compared to its span.
Types of Loads on a Slab
Types of loads acting on a slab include
1.Dead load of the slab
2.Live load
3.Floor finish load
4.Snow load in the case of roof slab
5.Earthquake loads
28. SLAB
Load Transfer Mechanism in Slabs
The forces transfer from slab to beams occur either in one way or in two
ways. The total system completely counts on the geometrical dimensions of
the slab. Slabs may be supported by columns only, in this case two way action
will prevail. If the ratio Long side / short side < 2 it is considered as 2-way slab,
and if Longer side to shorter side greater than 2 then it is considered as 1-way
slab. The load transfer mechanism from floor slab to supporting elements for
one way slab and two way slab are shown in Fig. 2 and Fig. 3. Lastly, Fig. 4
illustrate the transfer of loads from slabs to different types of supporting
elements.

31. Concrete
Concrete is the most commonly used construction material in the
industry. Concrete a thermal mass material; instead of it consisting of one
material, it is a mix of fine aggregate, cement, water, gravel, and stones.
These materials act as the foundation of many structures as well as in
superstructure construction. For example, through architectural features,
concrete is in structural concrete, stair construction, and slab
construction. Now, how is concrete used in construction projects?
How is concrete used in construction projects?
Concrete is used in the following: basic foundations, exterior surfaces,
superstructures, floor construction, wastewater treatment facilities, and
parking lots/structures. To determine the quality of cement, the factors
include the accuracy of placement, appearance, and consolidation.
Although these three are important, the quality of concrete goes much
further.
32. Masonry
Common term that refers to brick, concrete block, and stone
Used to form load-bearing walls
Veneer wall supports its own weight
Mortar holds units together and have little or no tensile or
shear strength
Excellent fire-resistive qualities
33.
34. PLASTER
Plaster is a protective coating that is applied to
masonry in order to protect it from external
agents and damage. It consists of a mixture
between a mortar and a binder (hardener) that
allows the plaster to adhere to the wall

37. TILING
Tiles in building construction are thin plates or elements used to cover surfaces like
roofs, floors, and walls. Types of tiles and their applications are discussed. Tiles in the
present scenario are a primary element in bringing building interior as well as exterior
finishing and beauty.
HOW TO TILE
STEP 1: CHOOSING THE MATERIAL
Tile is one of the most popular materials used in both kitchen renovation and
bathroom renovation.
In recent years, its popularity has in fact continued to grow, becoming a frequently
sort after material in all areas of the house. Due to its cost-saving potential and ability
to rejuvenate a room with its beautiful colours, patterns or textures.
When it comes to deciding on the type of tile you want, it can often be a difficult
decision, with an array of different materials, each with their own benefits &
disadvantages.
It’s also important to think about where you plan to place your tiles. If you
are planning on tiling your hallway or kitchen, these are areas with a lot of footfall and
therefore require a material that is durable.
38. TILING
STEP 2: CUTTING CERAMIC TILES
When cutting your tiles, depending on the material you need to cut you’ll need to use
a tile cutter either a manual cutter or an electric cutter.
STEP 3: PREPARING THE SURFACE
Before you start, it’s important to make sure the surfaces you’ll be working on
are clean, dry and most importantly flat.
STEP 4: MIX THE ADHESIVE
One of the most important parts of learning how to tile successfully, is in getting the
adhesive mix right. It’s important to know how to mix adhesive correctly in order to
achieve the strongest bond possible and a long-standing installation.
STEP 5: APPLY THE ADHESIVE
When applying the adhesive, it is essential for there to be minimum 85% total
coverage beneath a tile for dry area placement (such as dry floors, fireplace etc.) and
95% coverage in exterior and wet areas (such as showers, bath surrounds etc.).
39. TILING
STEP 6: LAYING THE CERAMIC TILE
When it comes to finally laying your tile down, make sure that you ‘back-
butter’ your tile with adhesive. Back buttering is extremely effective in
increasing the bond of the mortar on the floor to the mortar on your tile
TOOLS NEEDED FOR TILING
It is important to choose the right tiling tools for the construction work,
depending on the use and the phase of the process.
