PLAN:
PLAN:
EXCAVATION:
 Excavation was carried out both manually
as well as mechanically.
 Normally 1-2 earth excavators (JCB’s)
were used for excavating the soil.
 The filling is done in layer not exceeding
20 cm layer and than its compacted.
 Depth of excavation was 5’4” from Ground
Level.
CONCRETING:
 After the process of excavation, laying of
plain cement concrete that is PCC is done.
 A layer of 4 inches was made in such a
manner that it was not mixed with the soil.
 It provides a solid bars for the raft foundation
and a mix of 1:5:10 that is, 1 part of cement
to 5 parts of fine aggregates and 10 parts of
coarse aggregates by volume were used in it.
CONCRETING:
 Plain concrete is vibrated to achieve full
compaction.
 Concrete placed below ground should be
protected from falling earth during and
after placing.
FOUNDATIONS:
 At our site, Raft foundations are used to
spread the load from a structure over a
large area, normally the entire area of
the structure.
 Normally raft foundation is used when
large load is to be distributed and it is
not possible to provide individual
footings due to space constraints that is
they would overlap on each other.
FOUNDATIONS:
 Raft foundations have the advantage of
reducing differential settlements as the
concrete slab resists differential
movements between loading positions.
MATERIALS:
CEMENT
 Portland cement is composed of calcium
silicates and aluminate and alumino
ferrite It is obtained by blending
predetermined proportions limestone clay
and other minerals in small quantities
which is pulverized and heated at high
temperature – around 1500 deg
centigrade to produce ‘clinker’.
MATERIALS:
 The clinker is then ground with small
quantities of gypsum to produce a fine
powder called Ordinary Portland Cement
(OPC).
 When mixed with water, sand and stone,
it combines slowly with the water to form
a hard mass called concrete.
MATERIALS:
SETTING OF CEMENT
 When water is mixed with cement, the
paste so formed remains pliable and
plastic for a short time.
 During this period it is possible to disturb
the paste and remit it without any
deleterious effects.
MATERIALS:
COARSE AGGREGATE
 Coarse aggregate for the works should be
river gravel or crushed stone .
 It should be hard, strong, dense, durable,
clean, and free from clay or loamy
admixtures or quarry refuse or vegetable
matter.
MATERIALS:
FINE AGGREGATE
 Aggregate which is passed through 4.75 IS
Sieve is termed as fine aggregate.
 Fine aggregate is added to concrete to
assist workability and to bring uniformity
in mixture.
BRICK WORK:
 Brickwork is masonry done with bricks and
mortar and is generally used to build
partition walls.
 In our site, all the external walls were of
concrete and most of the internal walls
were made of bricks.
 English bond was used and a ratio of 1:4 (1
cement: 4 coarse sand) and 1:6 were used
depending upon whether the wall is 4.5
inches or 9 inches.
BRICK WORK:
 TYPES OF BRICKS
 Bricks can be of two types. These are:
Traditional Bricks
 The dimension if traditional bricks vary from 21
cm to 25cm in length,10 to 13 cm in width and
7.5 cm in height in different parts of country.
 The commonly adopted normal size of
traditional brick is 23 * 11.5*7.5 cm with a
view to achieve uniformity in size of bricks
all over country.
BRICK WORK:
 Modular Bricks
 Pakistan standard institution has established a
standard size of bricks such a brick is known as a
modular brick.
 The normal size of brick is taken as 20*10*10
cm whereas its actual dimensions are 19*9*9
cm masonry with modular bricks workout to be
cheaper there is saving in the consumption of
bricks, mortar and labor as compared with
masonry with traditional bricks.
REINFORCEMENT:
 Steel reinforcements are used generally,
in the form of bars of circular cross
section in concrete structure.
 They are like a skeleton in human body.
Plain concrete without steel or any other
reinforcement is strong in compression
but weak in tension.
 Steel is one of the best forms of
reinforcements. Bars range in diameter
from 6 to 50 mm.
SHUTTRING:
 The term ‘SHUTTERING’ or ‘FORMWORK’
includes all forms, moulds, sheeting,
shuttering planks, walrus, poles, posts,
standards, leizers, V-Heads, struts, and
structure, ties, prights, walling steel rods,
bolts, wedges, and all other temporary
supports to the concrete during the
process of sheeting.
FORM WORK:
 Forms or moulds or shutters are the
receptacles in which concrete is placed,
so that it will have the desired shape or
outline when hardened.
 Forms are generally made of the materials
like timber, plywood, steel, etc.
 The steel form work was designed and
constructed to the shapes, lines and
dimensions.
REMOVEL OF FORM WORK:
 Forms were not struck until the concrete
has attained a strength at least twice the
stress to which the concrete may be
subjected at the time of removal of form
work.
 Form work was removed in such a manner as
would not cause any shock or vibration that
would damage the concrete.
 the form work was removed as soon as
possible after the concrete has set, to avoid
shrinkage cracking occurring due to the
restraint imposed.
STRUCTURAL COMPONENTS AGE:
 STRUCTURAL COMPONENT AGE
Footings 1 day
Sides of beams, columns, lintels, wall 2 days
Underside of beams spanning less than 6m 14 days
Underside of beams spanning over 6m 21 days
Underside of slabs spanning less than 4m 7 days
Underside of slabs spanning more than 4m 14 days
Flat slab bottom 21 days
CONCLUSION:
 This program played an important role to
break the conventional thought that
field works can be only implemented by
students who hold degree and people
who have an experience in building
construction.
 We have to acquire high confidence
level to deal with problems arise in a
building construction.
