2. Some of Important Engineering Question and Answer
1. What are the different types of slumps of concrete?
⇒ The different types of slumps are as follows:
a. True slump,
b. Shear slump,
c. Collapse slump
2. What is the slump value of concrete for normal RCC work?
⇒ It is 80 to 150 mm for normal RCC work and 25 to 50 mm for mass concreting.
3. What are the various steps involved in the process of concreting?
⇒ The various steps involved in the process of concreting are as follows:
a. Batching
b. Mixing
c. Transportation
d. Placing
e. Compaction
f. Finishing
g. Curing
4. What should be the minimum value of concrete cover?
⇒ It should not be less than double the stirrup bar diameter.
5. Why is the concrete cover value for different RCC Members?
⇒ The concrete cover value for different RCC Members are as follows:
a. Slab = 20 mm
b. Beam = 25 mm
c. Column = 40 mm
d. Footing = 50 mm
6. What is the standard size of a concrete cube?
⇒ 150mm × 150 mm × 150 mm
7. How many cubes are filled for 1 cubic meter of concrete?
⇒ Here is the calculation:
1 sample = 3 cube
1-5cum = 1
6 – 15 cum = 2
16 – 30 cum = 3
31 – 50 cum = 4
50 cum and above = 4 plus one additional sample for each 50 additional cum.
8. How much concrete gains strength after seven days?
⇒ 7 days – 65%
9. What is the soundness of cement?
⇒ It is a property that makes sure the cement does not show any considerable expansion once it has been set.
10. What are the names of different tests to check the concrete quality?
⇒ On fresh Concrete
a. Workability
b. Air Content
c. Setting Time
On hardened Concrete
a. Compressive strength
b. Tensile strength
c. Modulus of Elasticity
d. Permeability test
e. In situ test
