The process of removing concete form works
Correct Answer
A. Stripping
Explanation
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.

Assumption that plane section remain plane before and after bending implies:
Correct Answer
B. No shear deformation
Explanation
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.

As per IS 456:2000, a simply supported beam is considered as a deep beam when
Correct Answer
C. Span to depth ratio < 2.0
Explanation
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.

For effective depth = 500mm and width = 300mm, find the limiting moment of resistance of beam (kNm): (f_{ck} = 20 and f_{y} = 415)
Correct Answer
D. 206.95
Explanation
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.

A beam is built using M25 concrete and HYSD bars. In limit state design, the development length, Ld , in terms of diameter of reinforcement, forcompression zone is _______× φ. [Take Yield strength of HYSD bar = 415 MPa and Bond strength with plain bar (τ_{bd}) = 1.4 N/mm2]
Correct Answer
A. 32.2
Explanation
The development length, Ld, in terms of the diameter of reinforcement, for the compression zone in limit state design is 32.2 times φ. This means that the length required for the bond between the reinforcement and the concrete to develop its full strength is 32.2 times the diameter of the reinforcement. This calculation takes into account the yield strength of the HYSD bar and the bond strength with plain bar.

Curing Period X Temperature = .......
Correct Answer
B. Maturity
Explanation
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.
