6.  The residential building is constructed in NGO nagar
tirupattur.
 It is a framed RCC structure.
 The total area is 2400 sq.ft.
 The built up area is 3696 sq.ft

10.  Plain cement concrete (PCC) is used to provide rigid
impervious bed to RCC in foundation where the earth is
soft and yielding.
 Plain cement concrete can also called only “cement
concrete (CC)” or “binding concrete”. M 25 grade of
concrete is prepared .
 materials used are cement,fine aggregate,coarse
aggregate and water.

11.  Cement may be described as a material with adhesive and
cohesive properties that make it capable of bonding mineral
fragments (‗aggregates‘) into a compact whole. In this
process, it imparts strength and durability to the hardened
mass called concrete.
 The cements used in the making of concrete are called
hydraulic cements so named, because they have the property
of reacting chemically with water in an exothermic (heat
generating) process called hydration that results in water
resistant products.
 We generally use Portland cement in PCC.
9-Nov-18 11

12.  Sand is used as fine aggregate in PCC. The fineness modulus
of sand should be 1.2 to 1.5.
 We normally use brick chips for producing PCC. Stone chips
can also be used for this purpose. The size of the coarse
aggregate is 20mm downgrade
 A number of tests have been described to assess the quality of
the aggregate, in terms of the following physical and
mechanical properties.
 Particle size,shape,water content,strength,water
absorbtion,specific gravity.
9-Nov-18 12

13.  Water has a significant role to play in the making of concrete
— in mixing of fresh concrete and in curing of hardened
concrete.
 In order to ensure proper strength development and durability
of concrete, it is necessary that the water used for mixing and
curing is free from impurities such as oils, acids, alkalis, salts,
sugar and organic materials.
 Water that is fit for human consumption (i.e., potable water) is
generally considered to be suitable for concreting. However,
when the portability of the water is suspect, it is advisable to
perform a chemical analysis of the water.
9-Nov-18 13

14.  Concrete mix proportion is 1:1.5:3.
 M25 grade of concrete is prepared.
 Manual mixing is done, as the site is small and
requirement is also less.

17.  As fresh concrete is in plastic state when it is placed for
construction purpose so, it becomes necessary to provide
some temporary structure to confine and support the concrete
till it gains sufficient strength for self-supporting.
 This temporary structure is called form work. Concrete
formwork serves as a mold to produce concrete elements
having a desired size and configuration.
 It is usually erected for this purpose and then removed after
the concrete has cured to a satisfactory strength. In some
cases, concrete forms may be left in place to become part of
the permanent structure.
9-Nov-18 17

18. The formworks of any type and of any place will
be required:
 To be rigid enough to confine plastic concrete at the lines
grades and dimensions indicated on the form plans without
bulging or sagging under the load,
 To be constructed as mortar tight as possible to prevent the
loss of concrete ingredients throughout the joints between the
sections.
 To be easy to remove with minimal damage to the concrete
surface.

19.  Traditional timber formwork.
 Engineered Formwork
 Reusable plastic formwork
 Permanent Insulated Formwork
 Flexible formwork.

29.  A column or pillar in architecture and structural engineering is a
structural element that transmits, through compression, the
weight of the structure above to other structural elements below.
In other words, a column is a compression member.
 Columns are frequently used to support beams or arches on
which the upper parts of walls or ceilings rest. In architecture,
"column" refers to such a structural element that also has certain
proportional and decorative features.
 A column might also be a decorative element not needed for
structural purposes.

30.  First we set the mould for the column .
 Then the reinforcement for the column was decided.
 Reinforcement was placed ,stirrups we placed ,then
mould was placed .
 Concrete was prepared and poured in the mould.
 Compaction was done(25 times compaction in each
layer) .

35. During the period of my internship, I have faced some problems at the
office and the site,some of the problems are :
 Communication problem with workers in the office and at the site.
 Shortage of working drawings like structural, architectural, sanitary,
electrical and some other details.
 Weather condition of the site.
 Shortage of knowledge in some portion of the work at the site.
 Underestimation by workers such as engineers.
 Unsatisfactory answers for questions from engineers.
 Safety facility.
9-Nov-18 35

36.  The internship is not only depending on the practical aspect
but it also help students to upgrade or increase knowledge on
already that they have.
 The aim of the internship is to address more practical knowledge
for student.
 I have improved my interpersonal communication skills,team
playing skills, leadership skills entrepreneurship skills during
the internship period.
 Practical application of theoretically studied work is viewed on
site.
