Civil Engineering - Concrete Technology - Discussion

Discussion Forum : Concrete Technology - Section 5 (Q.No. 11)
Pick up the incorrect statement from the following:
Workability of the concrete mix decreases with an increase in the moisture content
Concrete for which preliminary tests are conducted, is called controlled concrete
Bulking of sand depends upon the fineness of grains
Concrete mix 1 : 6 : 12, is used for mass concrete in piers.
All the above.
Answer: Option
No answer description is available. Let's discuss.

I agree with you @Shahzaib Rao.

Let me explain the option clearly.

Bulking depends upon Particle Size ---> Fineness &

Moisture Content (Option C is correct).

Test conducted in a laboratory on the trial mix of concrete produced in the laboratory for designing a concrete mix. It is done before actual concreting at the site to verify the strength of concrete and determine the adjustments required in the mix if needed. Thus, a concrete for which a mix is designed after carrying out the preliminary test is called controlled concrete. ((Option B is correct).

1:3:6 is used for abutments and piers. (Option D is incorrect).

Here only B and C options are right.

Mohsin Aziz said:   3 years ago
Option A will be the answer.

Shubham Gadge said:   3 years ago
Option A should be the answer.

Mamtameena said:   4 years ago
Bulking of sand also depend on fineness of Sand so option A is the correct answer.

Rakesh said:   4 years ago
Bulking also depends on size of fine aggregate.

Hardik said:   4 years ago
I think C is not correct because bulking of sand is depend upon moisture content.

Not cement water, it is water cement ratio.
