The ozonation in drinking water helps to remove

Detailed Solution for APSC JE CE Paper 2 Mock Test - 9 - Question 18
Because of its excellent disinfection and oxidation qualities, ozone is widely used for drinking water treatment. Ozone can be added at several points throughout the treatment system, such as during pre-oxidation, intermediate oxidation, or final disinfection.

With storage, the strength of cement:

Detailed Solution for APSC JE CE Paper 2 Mock Test - 9 - Question 26
  • Due to the hygroscopic nature of cement, it easily absorbs moisture from the atmosphere

  • This moisture or dampness is the main hazard for cement which makes it hard like stone and it converts it to a useless material not suitable for construction.

  • Storage of cement requires more care as strength of cement decreases with time

  • Storage of cement should be done in such a manner that it is not exposed to the atmosphere which can be done by packing in airtight bags.

Hence, the correct option is (B)

APSC JE CE Paper 2 Mock Test - 9 - Question 27

Direct shear test can be conducted for :

Detailed Solution for APSC JE CE Paper 2 Mock Test - 9 - Question 27
1. Unconsolidated Undrained Test (UU)

Drainage is not permitted throughout the test. In the case of direct shear test drainage is not permitted during the application of both normal stress and shear stress. In the case of triaxial compression test drainage is not permitted during the application of both cell pressure and deviator stress. Since the test is conducted fast allowing no time for either consolidation of sample initially or dissipation of pore pressure in later stage, the test is also called quick test.

2. Consolidated Undrained Test (CU)

In this type of shear test the soil specimen is allowed to consolidate fully under initially applied stress and then sheared quickly without allowing dissipation of pore pressure. In the case of direct shear test the specimen is allowed to consolidate fully under applied normal stress and then sheared at high rate of strain to prevent dissipation of pore pressure during shearing. In the case of triaxial compression test the specimen is allowed to consolidate fully under the applied cell pressure and then the pore water outlet is closed and the specimen is subjected to increasing deviator stress at higher rate of strain.

3. Consolidated Drained Test (CD)

In this type of shear test drainage is allowed throughout the test. The specimen is allowed to consolidate fully under the applied initial stress and then sheared at low rate of strain giving sufficient time for the pore water to drain out at all stages. The test may continue for several hours to several days.

Hence, the correct option is (D)

APSC JE CE Paper 2 Mock Test - 9 - Question 28

Which one of the following is not a classification of stones?

Detailed Solution for APSC JE CE Paper 2 Mock Test - 9 - Question 28
