Plastering as Building Finishes and the Defects
Plastering is enhancing the aesthetic value and hygiene condition in a building.
Plaster finished surface also gives insulation to thermal, fire and sound. The surface
finish can be obtained as smooth, semi-rough or rough as per the desired aesthetic
appearance using ganging trowel, Regi foam and sponge. Cement sand mortar is used
as the plaster mix.
IMPORTANT ASPECTSTO BE CONSIDEREDWHEN PLASTERING
 Plastering work should be levelled, plumbed up and the joints should be at
right angle at the corners or edges.

14. 1
4
 It must cover the non-verticality and non-horizontality of walls and columns
which are resulting from poorworkmanship and non-standard bricks.
 Generally, the plaster thickness should not exceed 15 mm. Else the mortar
bulk might tend to fall due to its self-weight and thus the cracks canbeinitiated
in later stages.
 The mortar mix proportionofcement: sand = 1:5 is generally used for the wall
plastering.
PROCEDUREFOR PLASTERING
It is must to ensure all mechanical and electrical work which associated with the
plaster surface should be completed before commencing plastering. Any holes left
in the wall orhoneycomb effect should befilled with constructiongrout. The surface
should be cleaned well to remove the dusts, loose particles and efflorescence in
bricks and then it should be wetted thoroughly.
1:5 cement: sand mortar should be mixed thoroughly and applied on the prepared
surface from top to bottom and levelled by using the straight edge and plumb bob.
After plastering, curing should be done for entire plastered surface. The curing
should be continued forat least 7 days to protectthe plastered surface from initiation
of thermal cracks.
DEFECTS IN PLASTERING
The defects in the plasterwork can be caused due to several reasons. The bricks,
mortar and concrete have some amounts of voids themselves. Moisture movement
that is causing by drying process of moisture inside the bricks, mortar and concrete
during the initial setting out or due to absorption of moisture from environment and
expand is main reason for the crack development. Quality of bricks used,

15. 1
5
workmanship of brickwork or plastering work, quality of mortar mix used, water
containing salt used for mortar mixture and dry condition of the plaster surface are
some other reasons for the defects in the plastering.
Proper proportioning and mixing of contents and good workmanship (avoid excess
troweling) is important to prevent the surface from cracking.
Crazing and Map cracking, De bonding, Lack of hardness, Grinning, Expansion,
Popping and Blistering are the possible defects in the plaster surface.
 Crazing is caused because of over troweling the mortar with high cement
content. This can be covered easily with the reasonable quality paint with
appropriate filler.
 De bonding is dueto different shrinkage rate through the plaster thickness and
can be noticed if a hollow sound is heard when tapping the surface. The main
reason for this type defect is the excessive thick plaster layers. Cleaning the
surface well to remove dusts and oil, damp the wall properly and applying the
cement slurry coat on the surface before plastering can be minimized the de
bonding.
 Lack of hardness can be observed only by scratching the surface and this is
causing due to insufficient cement content, using the sand with excess dust
and adding some more water after first mixing (re tempering).
 Grinning is due to excess troweling.


16. 1

 In the case of drying shrinkage cracks, the crack should be dug along the
crack as a ‘V’ notch up to 10 mm or up to crack depth with 10 mm wide. This
v notch should be made to ensure a bonding with the infill material
(construction grout). Then the surface should be cleaned well to obtain dust
free surface and made it wet. The construction grout can be mixed with water
and applied on the cleaned ‘v’ notch.
Types of cracks: Cracks may be divided in two categories viz
Structuralcracks
Non structuralcracks
i) Structural cracks:
Structural cracks may arise due to various reasons such as incorrect design,
overloading of the structural components, overloading of the soil on which the
building is constructed or other similar factors. Structural cracks endanger the
stability of the building and may be difficult to be rectified. Extensive cracks of
foundations walls, beams, columns or slabs etc, are examples of structural cracks.
ii) Non- structural cracks:
Non- structural cracks are generally due to internal forces developed in the
buildings on account of change in the size of building components, due to moisture
variation, temperature variations, the effect ofgases, liquid and solids on the building
components. The non-structural cracks can be repaired provided the reasons for
cracks are identified and suitable remedial measures are taken to prevent their
reoccurrence.

Investigationrelating to cracks:
A careful study of the locations of cracks (starting and finishing points) their width
and depth helps in dealing with the diagnosis of different types of cracks.
The following information helps in diagnosing the cracks:
i. Whether the crack is old or new.
ii. Whether it appears on the oppositeface of the member also.
iii. Pattern of the cracks.
iv. Soil condition, type of foundation used, and movement of ground if any.
v. Observations on the similar structures in the same locality.Study ofspecification,
method of construction, used and the test result at the site if any
vi. Climatic condition during which the structure has been constructed.
Limitation of crack width (IS 456:2000):
Depending on the exposure conditions limitations on crack width are imposed as
follows
1. For members in water storage units, sewage treatment plants, structures in
chemically hazardous atmosphere, etc. Cracks are not permitted in R.C.
members.
2. In severe atmosphere up to 0.1mm crack width is permitted.
3. Moderate atmosphere up to 0.2mm crack width is permitted.
4. In mild atmosphere the surface width of cracks should not, in general exceed
0.3mm in members where cracking does not have any serious adverse effects
upon the preservation of reinforcing steel nor upon the durability of structure.
Permissible crack width in reinforced structure as per ACI
Exposure conditions Maximum allowable crack width in

Dry air, protective membrane 0.41
Humidity, moist air 0.30
Sea water and seawater spray; Wetting and

0.15
Water retaining structure 0.10
II) CAUSES FOR THE OCCURANCE OF CRACKS:

18. 1

The importance causes responsible for occurrence of the cracks are
1.structural deficiency resulting from design deficiency or construction deficiency
and overloading.
2. Settlement of ground
3.Temperature and Shrinkage effects.
4. Cracks due to faulty workmanship and poorconstruction practice
Cracks due to structural deficiency resulting from design deficiency or
constructiondeficiency and overloads.
Concrete structure and individual members all carry loads. Some carry only the
weight of the materials they are made of, while others carry loads applied to the
structure. All material change volume when subjected to stress,
Concrete is no exception. When subjected to tensile stress, concrete stretches; when
subjected to compressive stress it shortens. Concrete possesses high compressive
strength but little tensile strength, and reinforcing steel provides the needed strength
in tension. The loads induced during construction can be far more severe than they
are experienced in service. Concrete problems, such as excessive deflection,
cracking may be caused by volume changes associated with load effect.
 Cracks occurdue to shear, flexural and torsional steel deficiency.
 Cracks occurdue to abrupt curtailment of reinforcing bars, construction joints
etc.
 Improper anchorage.
 Cracks due to overloading of members

Cracks due to shrinkage and temperature effect:
Shrinkagecrack:
Shrinkage cracks showup in two basic locations in mostwalls; the approximate
mid-point of a long section of wall, and the narrowed section of the wall such as
across a dooror window head. Shrinkage cracks are virtually uniform in width from
top to bottom and typically extend from the top of the wall to within a couple of feet
of the foundation.

Temperatureeffect:
Theeffect of temperature on concretestructure and member is one of volume
change. The volume relationship to temperature is expressed by the coefficient of
thermal expansion/contraction. Volume changes create stress when the concrete is
restrained. The resulting stress can be of any type: tension, compression, shear, and
etc. the stressed conditions may result in undesirable behavior such as cracking,
spalling and excessive deflection.
Cracks due to settlement:
Uneven (differential) settlement can be a major structural problem in small
residential buildings, although serious settlement problems are relatively uncommon.
Many signs ofmasonry distress are incorrectly diagnosed as settlement-related when
in fact they are due to moisture and thermal movements.
Indications of differential settlement are vertical distortion or cracking of
masonry walls, warped interior and exterior openings, sloped floors, and sticking
doors and windows. Settlement most often occurs early in the life of a building or
when there is a dramatic change in underground conditions. Often suchsettlement is
associated with improper foundation design, particularly inadequate footers and
foundation walls.

21. 2

Gradual differential settlement over a long period of time may produce no
masonry cracking at all, particularly in walls with older and softer bricks and high
lime mortars; the wall will elastically deform instead. More rapid settlements,
however, produce cracks that taper, being largest at one end and diminishing to a
hairline at the other, depending on the direction and location of settlement below the
wall.
Cracking is most likely to occur at corners and adjacent to openings, and usually
follows a rough diagonal along mortar joints (although individual masonry units may
be split). Settlement cracks (as opposed to the similar-appearing shrinkage cracks
that are especially prevalent in concrete block) may extend through contiguous
building elements such as floor slabs, masonry walls above the foundation, and
interior plaster work. Tapering cracks, or cracks that are nearly vertical and whose
edges do not line up, may occur at the joints of projecting bay windows, porches,
and additions. These cracks indicate differential settlement due to inadequate
Cracks due to faulty workmanship and poor constructionpractice:
Methods used to construct concrete structures are different from methods used in
other type of construction. Concrete is one of the few materials in which raw
ingredients are brought together at, or near, the construction site, where they are
mixed, placed and molded into a final product. Every building process includes a
sequence of necessary step-by-step operation-from conceptual plan to finished
structure. There are so many variables affecting the productionof concretethat there
is always a potential for something to go wrong.

Chapter 3: CONCLUSION
Conclusion
The 6 weeks training that I received at U.P.P.W.D. was great
experience for me not only on technical terms but also in terms of
interaction with other workers. I learnt a great deal on applying the
knowledge I have gained at the University. Learning something from
books and lectures is nothing like having firsthand experience. At
Loadstar I got to apply my Civil Engineering knowledge. The
company gives the full freedom for the trainee to get a sufficient
training. The trainees are allowed to ask and do anything relevant to
the training. Engineers are always very enthusiastic on giving us the
best training experience. The employees do not think of their
designation but only on the work to be done. Teamwork has been
excellent and all of them are like best friends,even with lowerranked
employees like Drivers, Office aids. And also they are most often at
the sites with all kinds of employees.Everyone was friendly fromtop
to bottom. Employees are busy with their work but they always help
us to improve our knowledge.
Drawbacks during the training
A drawback I see in U.P.P.W.D is that it has many health hazards.
Employees are exposed to large amounts of dust. When inhaled,
these particles can cause serious lung disease. Even though there is a
rule to wear protective masks, employees do not do so most of the
time. They should be urged to wear protective gear and lectured on
negative consequences of not wearing them. Also unlike in CEB
where the safety is measured by the number of accidents in a given

23. 2
3
time period, in Loadstar, it is the number of deaths that is shown. I
attached the copy of the Certificate obtained by U.P.PWD.
Future Scope
As an undergraduate of the SMS Lucknow I would like to say that
this training program is an excellent opportunity for us to get to the
ground level and experience the things that we would have never
gained through going straight into a job. I am grateful to U.P.P.W.D
for giving us this wonderful opportunity. The main objective of the
industrial training is to provide an opportunity to undergraduates to
identify, observe and practice how engineering is applicable in the
real industry. It is not only to get experience on technical practices
but also to observe management practices and to interact with fellow
workers. It is easy to work with sophisticated machines, but not with
people. The only chance that an undergraduate has to have this
experience is the industrial training period. I feel I got the maximum
out of that experience. Also I learnt the way of work in an
organization, the importance of being punctual, the importance of
maximum commitment, and the importance of team spirit. The
training program having three destinations was a lot more useful than
staying at one place throughout the whole six weeks. In my opinion,
I have gained lots of knowledge and experience needed to be
successful in a great engineering challenge, as in my opinion,
Engineering is after all a Challenge, and not a Job.
