2. The shape of aggregate which is best for interlocking is _____
a) Angular
b) Rounded
c) Elongated
d) Edgy
View Answer

Answer: a
Explanation: Angular shaped aggregate increases the interlocking in concrete as cement is easily bounded on it.

3. The section in which quantity of steel required is different in tension and compression.
a) Balanced
b) Under Balanced
c) Over Balanced
d) Unbalanced
View Answer

Answer: d
Explanation: This is a section in which quantity of steel required is different from that in balanced section.

4. Which IS code is followed for designing medium tensile conforming bars?

b) IS 3320
c) IS 432
d) IS 1139
View Answer

Answer: c
Explanation: IS 432 is used for medium tensile conforming bars and IS 1139 is followed for medium tensile steel bars.

5. After curing concrete for 28 days, how much strength will it attain?
a) 10-20%
b) 20-50%
c) 50-80%
d) 90-95%
View Answer

Answer: d
Explanation: Normally concrete is cured for 28 days to check its compressibility because it attains of about 90-95% of its strength in that period.

6. What is the size of vicat needle used for cement testing?
a) 10mm Dia
b) 1mm Square
c) 3mm Square
d) 15 mm Dia
View Answer

Answer: a
Explanation: Vicat’s apparatus consists of an arrangement to hold the plunger of 10 mm diameter and two other needles which are made to freely fall into a mould filled with the cement paste and the amount of penetration of the needles of plunder can be noted using the vertical graduations from 0 mm to 50 mm.
