APSC JE CE Paper 2 Mock Test - 10 - Civil Engineering (CE) MCQ

Bitumen adheres well to all normal types of road aggregates provided they are dry and free from dust. In the absence of water, there is practically no adhesion problem of bituminous construction. Adhesion problem occurs when the aggregate is wet and cold. This problem can be dealt with by removing moisture from the aggregate by drying and increasing the mixing temperature. Further, the presence of water causes stripping of binder from the coated aggregates. These problems occur when the bitumen mixture is permeable to water. 

IRC has specified the maximum value of stripping value of aggregate not to exceed 5%.

(→) The rate of consolidation increases with the temperature.

( → ) Decrease with the increase of liquid limit

( → ) Changes with the increase in effective stress etc.

(→) It is a field test, which is generally performed on uniform sandy soil.

(M/I=σ_b/Y=E/R)

Hence the option A is correct.

Hence the option D is correct.

Hence the correct answer is option C.

Hence the correct answer is option d.

360°-87° = 273°.

Hence, the correct option is (b).

In the case of driven piles in loose- to medium-dense sand, the efficiency of a pile group may be even greater than 1 due to the densification of the sand between the piles during the driving operation. In this case, the efficiency of the pile group is equal to 1 or 100%.

Hence the correct answer is option C.

Hence the correct answer is option B.

Hence correct answer is option B.

The maximum deflection of the tip of the cantilever beam with concentrated load P at the free end is Pl³/3EI

Hence the correct answer is option A.

Hence the correct answer is option B.

Hence, the correct option is (B).

(=3×23 – 3 × 3 = 0)

Hence it is determinate and stable.

In general: If The structure is number of unknowns < number of equations Unstable number of unknowns = number of equations

Stable & Determinate number of unknowns > number of equations Indeterminate The procedure outlined above does not always work with regard to stability. An alternate method (the displaced shape method) of determining whether a structure is stable or unstable, and determinate or indeterminate is the following

• If the displaced shape of the structure can be drawn so that no members deform, the structure is unstable.

• If the displaced shape cannot be drawn without causing a member to deform, the structure is stable.

If removal of one constraint (a support force or a member force) causes the structure to be unstable (i.e. the structure can be displaced without deforming a member), then the original structure is stable and determinate. o If two or more constraints need to be removed to cause the structure to be unstable, the original structure is stable and indeterminate.

Hence, the correct option is (A)

Hence, the correct option is (A)

• If grain size increases the permeability of soil will increase

• The permeability will increase if the void ratio increases

• The structural arrangement of the soil particle will influence the void ratio and thus permeability

• bar screening;

• straining;

• comminution;

• grit removal

• Flow equalization chamber

• Proportion tank

• Neutralization for pH adjustment tank

Nutrient removal tank is the secondary treatment process.

A lower ratio leads to higher strength and durability but may make the mix difficult to work with and form.

The water-cement ratio is inversely proportional to the strength of concrete, lower water-cement ratio leads to an increase in bonds between the aggregates, cement, and sand.

As w/c increases quantity of cement in concrete reduces hence the availability of paste in concrete reduces. Poorer the paste higher the creep. therefore we can say that strength of concrete is inversely proportional to the creep.
