QUESTIONS & SOLVED ANSWERS/SOLUTIONS

Question 101: What will be the depth of penetration of the plunger in Vicat Apparatus IS : 5513 - 1976 from the bottom of the Vicat Mould, when the cement paste is tested for standard consistency, according to IS 4031-1988 ?

(a) 11 to 15 mm

(b) 8 to 10 mm

(c) 15 to 17 mm

(d) 5 to 7 mm

Answer - D

Explanation:
As per Consistency Test (IS 4031 - Part 4 1988)
In order to find initial setting time, final setting time and soundness of cement standard consistency is required.
Standard consistency is defined as consistency of cement paste, which permits "Vicat Apparatus" of dia 10 mm and height 50 mm to penetrate in the mould, upto the depth of (33-35 mm) from top and (5-7mm from bottom.
This test is performed at temp of (27±2°C) and humidity (65±5)%
The purpose of this test is to find water content required to prepare cement paste of standard consistency.

Question 103: Select the correct statement with respect to an over-reinforced cement concrete section under the working stress method.

(a) The compressive stress in steel reaches the allowable limit before the maximum tensile stress in concrete reaches the allowable limit

(b) Tensile steel stress and maximum compressive stress in concrete simultaneously reach their allowable limits.

(c) The allowable limiting stress is reached in concrete before the steel stress reaches the limiting value.
(d) The tensile stress in steel reaches the allowable limit before the maximum compressive stress in concrete reaches the allowable limit.

Answer - C 

Explanation:

In working stress method when the section is over-reinforced then the concrete reaches first at the vield allowable limiting stress than steel and vice versa.

Question105: What is the principle of plane surveying?

(a) Working from part to whole
(b) Working from point to area
(c) Working from angle to volume
(d) Working from whole to part

Answer - D 

Explanation:

Principle of surveying

• To work from whole to the part
• To locate a new station by at least two measurement from fixed reference points

Principle of surveying: The purpose of this process of working is to prevent accumulation of error, during this procedure, if there is any error in the measurement of any side of a triangle, then it will not affected the whole work. The error can always be deducted and eliminated.

Question 108: What is the effect of fly ash in concrete?

(a) Reduces the secondary hydration process
(b) Increases the heat of hydration
(c) Increases the amount of air entrainment
(d) Reduces the heat of hydration

Explanation:
Answer - D

Effect of fly ash on cement concrete.

Effect on strength- Since the action of pozzolana is slow, addition of fly ash upto 30% may result in lower strength at 7 and 28 days, but may be about equal at 3 months and may further increase at ages greater than 3 months after curing period if continued. 

• On modulus of elasticity- It is lower at early ages and higher at later ages.
• On permeability- It reduces permeability of concrete because of its fineness.
• On resistance of chemical attack- It improve resistance against chemical attack.
• On heat of hydration- It reduce heat of hydration
• On setting time- It increases initial setting time of cement upto 2 hours.

Question 114: Select the correct option with regard to the following statements (S1, S2 pertaining to pavements.
S1: Present serviceability index is used for the functional evaluation of pavement surface condition.
S2: Rigid pavements are less affected by temperature variations than flexible pavements.

• Statement S1 is true and Statement S2 is false.
• Both statements S1 and S2 are false
• Statement S1 is false and Statement S2 is true
• Both Statements S1 and S2 are true

Answer - A 

Explanation:

• Present serviceability index is used for the functional evaluation of pavement surface condition.
• Rigid pavements or concrete pavements are highly impacted by temperature changes through alterations in expansion and contraction movements and subsequently cracks form.
• Temperature variations cause curling and thermal-expansion stresses within the concrete.

Question 118: Which of the following is Kharif season in India?

(a) March/April to June/July
(b) December/January to April/May
(c) May/June to October/November
(d) October/November to April/May

Answer - C 

Explanation:

• Kharif season starts from May/June and end on October/November.
• Rabi season starts from November and ends on March/April.
