Q1. Under and over reinf of beam and column
Ans. 
Under and over reinforcement in beams and columns refers to the amount of reinforcement provided in relation to the required strength of the structure.
• Under reinforcement occurs when the amount of reinforcement provided is less than what is required for the structure to carry the design loads.

• Over reinforcement occurs when the amount of reinforcement provided is more than what is required for the structure, leading to ...read more

Q2. Grades of concrete
Ans. 
Grades of concrete refer to the strength of the concrete mix design.
• Grades of concrete are denoted by M10, M15, M20, etc. where M stands for mix and the number represents the compressive strength in N/mm^2.

• Higher grade concrete has higher compressive strength and is used for structural purposes.

• Common grades include M25, M30, M35, and M40 for heavy-duty structures like bridges and high-rise buildings.

Q3. What is slump in concrete
Ans. 
Slump in concrete refers to the measure of consistency of freshly mixed concrete.
• Slump is determined by the amount of water in the concrete mix.

• It is measured by filling a cone-shaped mold with concrete, then lifting the mold to see how much the concrete slumps.

• Different types of slumps (true slump, shear slump, collapse slump) indicate different levels of workability and strength of the concrete mix.

• Slump test is comm...read more

Q4. What is water cement ratio
Ans. 
Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
• Water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The ideal water cement ratio varies depending on the type of concrete mix and its intended use.

• For example, a water cement ratio of 0.5 is commonly used ...read more

Q2. No of brick in 1 cubic meter
Ans. 
The number of bricks in 1 cubic meter varies depending on the size of the bricks used.
• The number of bricks in 1 cubic meter will depend on the size of the bricks being used.

• Standard size bricks (190mm x 90mm x 90mm) will have a different count compared to larger or smaller bricks.

• Calculations can be done by dividing the volume of 1 cubic meter by the volume of a single brick.

Q1. How to do layout, how to calculate column ring cutting length
Ans. 
Layout is done using measurements and tools, column ring cutting length is calculated based on the diameter and height of the column.
• Use measuring tape and chalk to mark the layout according to the blueprint

• Calculate the column ring cutting length using the formula: 2 x π x radius + height

• Ensure accuracy in measurements to avoid errors in construction

Q1. What is SI unit of inductance
Ans. 
The SI unit of inductance is Henry (H).
• Inductance is the property of an electrical circuit that opposes a change in current.

• It is measured in Henry (H) and is named after American scientist Joseph Henry.

• Inductance is used in various electrical components such as transformers, inductors, and motors.

• The symbol for inductance is L and it is measured in units of Henry per meter squared (H/m^2).
