This set of Concrete Technology Interview Questions and Answers for freshers focuses on “Complexity in Special Concrete, India in SCC”.
1. In a dry environment, concrete strength will be loosed as much as __________ % in moist environment.
a) 30
b) 40
c) 50
d) 60
View Answer
Explanation: Laboratory tests show that concrete strength will be loosed as much as 50% in dry environment as compared to moist environment.
2. After finishing concrete surface must be kept __________
a) Dry
b) First dry it and then wet it
c) First wet it and then dry it
d) Wet
View Answer
Explanation: After finishing concrete surface must be kept wet, so that it’d be prevented from evaporation.
3. A ___________ paste structure undergoes ___________ creep.
a) Good, high
b) Poor, high
c) Good, average
d) Poor, low
View Answer
Explanation: The amount of paste content and its quality is one of the most important factors influencing creep. A poorer paste structure undergoes higher creep.
4. SCC has __________ yield stress.
a) Low
b) High
c) Medium
d) 75%
View Answer
Explanation: Self-consolidating concrete or self-compacting concrete (commonly called as SCC) is a concrete mix which has a low yield stress.
5. SCC has __________ deformability.
a) Low
b) High
c) Medium
d) 75%
View Answer
Explanation: Self-consolidating concrete or self-compacting concrete (commonly called as SCC) is a concrete mix which has a high deformability.
6. SCC has __________ viscosity.
a) Low
b) High
c) Medium
d) 75%
View Answer
Explanation: Self-consolidating concrete or self-compacting concrete (commonly called as SCC) is a concrete mix which has a medium viscosity.
7. SCC has ___________ segregation resistance.
a) Good
b) Bad
c) Average
d) Poor
View Answer
Explanation: Self-consolidating concrete or self-compacting concrete (commonly called as SCC) is a concrete mix that has a medium viscosity and good segregation resistance.
8. SCC is measured using the _________
a) Picat’s apparatus
b) Slump-flow test
c) Slump test
d) Standard Consistency Test
View Answer
Explanation: SCC is measured using Slump flow test rather than usual slump test, as it is too fluid to keep its shape when the cone is removed from it.
