Test: B.M.C Soil,Concrete- 2 - Question 7

In doubly reinforced sections, total reinforcement percentage of steel should not exceed:

Detailed Solution for Test: B.M.C Soil,Concrete- 2 - Question 7

Total Reinforcement Percentage in Doubly Reinforced Sections

- In doubly reinforced sections, the total reinforcement percentage of steel should not exceed 4.0%.
- This limit is set to ensure that the concrete is able to carry its share of the load and prevent excessive cracking or failure.
- Exceeding this limit can lead to premature failure of the structure due to overstressing of the concrete or steel reinforcement.
- It is important to carefully calculate and design the reinforcement layout in doubly reinforced sections to ensure that this limit is not exceeded.
- Structural engineers should always consider the maximum allowable reinforcement percentage when designing doubly reinforced sections to ensure the safety and integrity of the structure.

Test: B.M.C Soil,Concrete- 2 - Question 8

A simply supported beam is considered as a deep beam if the ratio of effective span to overall depth is less than:

Test: B.M.C Soil,Concrete- 2 - Question 9

The term ‘Characteristic load’ means that load which has a probability of not being exceeded,during the life of the structure is equal to:

Test: B.M.C Soil,Concrete- 2 - Question 10

For reinforced concrete members totally immersed in sea water, the additional cover thickness recommended by the code is:

Test: B.M.C Soil,Concrete- 2 - Question 11

If the soil sample is having porosity 50% and degree of saturation at 90% then its percentage air voids is:

Detailed Solution for Test: B.M.C Soil,Concrete- 2 - Question 11

Test: B.M.C Soil,Concrete- 2 - Question 12

The commonly used method for quick determination of water content at field embankments is:

Test: B.M.C Soil,Concrete- 2 - Question 13

The toughness index is define as the ratio of:

Detailed Solution for Test: B.M.C Soil,Concrete- 2 - Question 13

Concept:
Toughness Index: Toughness index is defined as the ratio of plasticity index (IP) of the soil to the flow index (IF) of the soil. The toughness index varies between 0 to 3.

This gives us an idea of the shear strength of soil at its plastic limit.

When the toughness index is less than 1, the soil is said to be friable, which means it can be easily crushed at the plastic limit.

Test: B.M.C Soil,Concrete- 2 - Question 14

According to Atterberg, the soil is said to be of medium plasticity if the plasticity index (PI) is:

Test: B.M.C Soil,Concrete- 2 - Question 15

A soil has liquid limit 65%, plastic limit of 30% and shrinkage limit of 25%, and it has natural moisture content of 45%. The liquidity index of soil is.

Detailed Solution for Test: B.M.C Soil,Concrete- 2 - Question 15

Liquidity index = (water content-plastic limit)/(liquid limit-plastic limit).
= (45-30)/(65-30)
= 15/35
= 0.43

Test: B.M.C Soil,Concrete- 2 - Question 16

Void ratio of a soil is 0.9 its porosity shall be:

Test: B.M.C Soil,Concrete- 2 - Question 17

A soil has percentage air voids of the order of 30%. It has a porosity of 0.4 The air content of that soil shall be: -

Test: B.M.C Soil,Concrete- 2 - Question 18

The ratio of plasticity index and flow index of soil is called:

Test: B.M.C Soil,Concrete- 2 - Question 19

Test: B.M.C Soil,Concrete- 2 - Question 20

A negative value of the group index of a soil is reported as:

Test: B.M.C Soil,Concrete- 2 - Question 21

A soil with a plasticity index equal to zero may be called as:

Test: B.M.C Soil,Concrete- 2 - Question 22

The meniscus and dispersing agent corrections, in the hydrometer analysis, respectively are

Test: B.M.C Soil,Concrete- 2 - Question 23

An inorganic clay of high compressibility is represented by the symbol

Test: B.M.C Soil,Concrete- 2 - Question 24

If void ratio is 0.67, water content = 0.188 and Sp. Gr. = 2.68, the degree of saturation of soil is

Detailed Solution for Test: B.M.C Soil,Concrete- 2 - Question 24

Given,

e = 0.67, w = 0.188, G = 2.68

We know, Se = wG

S × 0.67 = 0.188 × 2.68

S = 0.752 = 75.2%

Test: B.M.C Soil,Concrete- 2 - Question 25

A sample of saturated clay has a porosity of 0.562, the void ratio of the clay is
