2. What is Guniting?
Ans: It is process in which mixture of sand and cement of 1:3 is shooted on concreate
surface with help of cement gun. It is highly effective process for repairing concrete walls or
damaged surfaces.
3. A wall constructed to resist the pressure of an earth filling is known as?
Ans: Retaining wall.
4. What is bearing capacity of soil?
Ans: Bearing capacity is the capacity of soil to support the loads applied to the ground by the
foundation of the structure.
5. What is recommended slump for column?
Ans: 75 TO 125 mm.
6. What is the minimum curing period for concreate?
Ans: Curing duration of concreate must be at least 07 days in OPC, at least 10 days for
concreate with mineral admixtures.
7. The portion of a brick cut across the width is called?
Ans: Bat.
8. What are common ways of demolition?
Ans:
 Hydro-demolition
 Pressure bursting
 Dismantling.
9. What is the minimum concreate grade for RCC work?
Ans: it should not be lower than M20.
10. What are the names of different tests to check the concreate quality?
Ans: workability, air content, setting time compressive strength, InSite test, permeasility test.
11. What material is used for filling cracks in masonry structure?
Ans: Plastic bitumen.
12. What is projection line?
Ans: A projection line is a way in which the earth is presented on flat piece of paper.
13. What is the allowable % of silt in the sand?
Ans: Not greater than 6%.
14. What is segregation?
Ans: Separation of ingredients of concreate from each other is known as segregation.
15. What is workability?
Ans: property of concreate with which it can be mixed , placed , consolidated and
finish easily is called workability.
16. Difference between one way and two-way slab?
Ans: One way slab is supported by beams in only two sides. Two way slab is
beams in all four sides.
supported by
17. Types of slump?
Ans: True slump, shear slump, collapsible slump.
18. Minimum numbers of bars in circular column?
Ans: 6 Bars.
19. What is the minimum diameter of bars used in slab?
Ans: 8mm.
20. How many types of building structure do you know considering the load and how
do you differentiate?
Ans: FRAME Structure: In which load is transferred from slab to beans and columns, the
load is then ultimately taken by the foundation and absorbed by adjacent soil.
Load Bearing Wall: In this building structure , loads are mainly carried by walls, columns and
beans.
