Stripping
- B.
clearing
- C.
Deforming work
- D.
Screeding
Correct Answer
A. StrippingExplanation
Stripping refers to the process of removing the formwork or molds that were used to shape and support the concrete during its curing process. This is typically done once the concrete has hardened and gained enough strength to support itself. Stripping allows for the reuse of the formwork for future projects and also exposes the finished concrete surface. The other options, clearing, deforming work, and screeding, do not accurately describe the process of removing formwork from concrete.Rate this question:

The target mean strength of concrete mix is given by
- A.
Ft = fck + KS
- B.
Ft = fck + S
- C.
Ft = fck + K
- D.
Ft = fck
Correct Answer
A. Ft = fck + KSExplanation
The correct answer is ft = fck + KS. This equation represents the target mean strength of a concrete mix. "ft" represents the target mean strength, "fck" represents the characteristic strength of concrete, "K" represents a constant, and "S" represents the standard deviation of the concrete mix. By adding the product of the constant "K" and the standard deviation "S" to the characteristic strength "fck," we can calculate the target mean strength "ft" of the concrete mix.Rate this question:

Assumption that plane section remain plane before and after bending implies:
- A.
Tensile strength of concrete is neglected
- B.
No shear deformation
- C.
Area of steel is taken to be constant
- D.
Steel fails in yielding
Correct Answer
B. No shear deformationExplanation
The assumption that plane sections remain plane before and after bending implies that there is no shear deformation. In other words, it assumes that the concrete does not experience any sliding or shearing along the plane section when it is subjected to bending forces. This assumption is commonly made in the analysis of beams and other structural elements, simplifying the calculations and allowing for easier determination of the bending moments and stresses. However, it should be noted that in reality, there can be some degree of shear deformation, especially in cases where the bending forces are significant.Rate this question:

As per IS 456:2000, a simply supported beam is considered as a deep beam when
- A.
Depth of beam > 750
- B.
Span to depth ratio < 2.5
- C.
Span to depth ratio < 2.0
- D.
Doesn’t depend on above parameter
Correct Answer
C. Span to depth ratio < 2.0Explanation
A simply supported beam is considered as a deep beam when the span to depth ratio is less than 2.0. This means that the span of the beam is relatively small compared to its depth. Deep beams are designed differently from regular beams because they experience higher shear and flexural stresses. Therefore, a span to depth ratio of less than 2.0 is an important criterion to identify a simply supported beam as a deep beam according to IS 456:2000.Rate this question:

For effective depth = 500mm and width = 300mm, find the limiting moment of resistance of beam (kNm): (fck = 20 and fy = 415)
- A.
235.5
- B.
210.55
- C.
211.9
- D.
206.95
Correct Answer
D. 206.95Explanation
The limiting moment of resistance of a beam can be calculated using the formula:
Mlim = (0.87 * fy * Ast * (d - a/2))/1000
Where:
Mlim = Limiting moment of resistance
fy = Yield strength of steel
Ast = Area of tension steel reinforcement
d = Effective depth of the beam
a = Depth of the compression block
Given:
Effective depth (d) = 500 mm
Width = 300 mm
fck = 20 MPa
fy = 415 MPa
To calculate the limiting moment of resistance, we need to determine the area of tension steel reinforcement (Ast) and the depth of the compression block (a). However, these values are not provided in the question. Therefore, an explanation cannot be generated.Rate this question:

Correct Answer
B. MaturityExplanation
The curing period is the time required for a material to reach its desired strength and durability. Temperature plays a crucial role in this process as it affects the rate of chemical reactions and the development of the material's properties. Maturity refers to the cumulative effect of time and temperature on the curing process. By measuring the temperature over time, the maturity of the material can be determined, which provides a reliable indicator of its strength and performance. Therefore, the equation "Curing Period X Temperature = Maturity" implies that the combination of time and temperature influences the maturity of the material during the curing process.Rate this question:

- D.
V/(9.5√R)
Correct Answer
D. V/(9.5√R)Explanation
The correct answer is V/(9.5√R). This formula represents the concept of psychological widening. The variable V represents the value or importance of a decision or event, while R represents the level of risk involved. By dividing V by 9.5 times the square root of R, the formula accounts for both the value and the risk, resulting in a measure of psychological widening. This suggests that as the value or risk increases, the psychological widening also increases.Rate this question:
