Q. 1 What
is Punching Shear?
Ans.
Punching shear is a type of failure of reinforced concrete slabs subjected to
high localized forces. In flat slab structures this occurs at column support
points.
Q. 2 The
standard sand now a days used in India is obtained from ?
Ans. Ennore
(madras)
Q.3 The
mixture of different ingredients of cement is burnt at temperature of ?
Ans. 1400
degree centigrade
Q.4 For
ensuring quality of concrete which aggregates are used?
Ans. Graded aggregates
Q.5 IN
Quality Control of Portland Cement, the test essentially done is ?
Ans. Setting time, Soundness, tensile strength,consistency.
Q.6 Why we
are not provide bar in the center of the column and bar?
Ans. Steel are provided for tension. In column max. tesile stresses are generated
along the column face.
Q.7 What is
soil analysis?
Ans. Soil
analysis is the testing of soil to determine the nutritional and elemental
composition of soil. It is generally tested for knowing the contents of
nitrogen, potassium and phosphorus.
Q.8 State
the applications of modulus of elasticity?
Ans. Modulus
of elasticity is related to the flexibility of the material. The value of
modulus of elasticity is pretty important in case of deflection of different
materials used in building construction.
Q.9 What is
the difference between sill beam,Tie beam and plinth beam?
Ans. 1 Sill
beam:- flexural member
2 Tie
beam:- fully compression member
3 plinth
beam :- loading from bottom (soil mass) is UDL so
4 main
reinforcement is in top of beam.
