Zydus Lifesciences Project Executive Engineer Interview Questions, Process, and Tips

TMT bars are used in construction for their high tensile strength, ductility, and resistance to corrosion.

• TMT bars have higher tensile strength compared to traditional mild steel bars, making them more suitable for construction of high-rise buildings and bridges.

• They have good ductility, allowing them to bend without breaking during earthquakes or other natural disasters.

• TMT bars are resistant to corrosion, ensuring th...read more

Thermo-Mechanically Treated bar

• TMT bar stands for Thermo-Mechanically Treated bar

• TMT bars are high-strength reinforcement bars having a tough outer core and a soft inner core

• They are widely used in construction for their superior strength and ductility

Structural steel bar weight can be calculated using the formula: weight = (d^2/162) * L, where d is the diameter of the bar in mm and L is the length of the bar in meters.

• Calculate the cross-sectional area of the steel bar using the formula: Area = (π * d^2) / 4, where d is the diameter of the bar in mm.

• Determine the weight of the steel bar by multiplying the cross-sectional area by the length of the bar and the densit...read more

A spirit level is used to determine if a surface is level or plumb.

• Used in construction to ensure buildings are level

• Helps in installing shelves, cabinets, and other fixtures accurately

• Used in carpentry to ensure straight and level cuts

• Also known as a bubble level due to the liquid-filled tube with a bubble inside

The code for concrete should be based on the specific project requirements and local building codes.

• The code for concrete can vary depending on factors such as strength requirements, exposure conditions, and environmental considerations.

• Common codes used for concrete include ACI 318 (Building Code Requirements for Structural Concrete) and ASTM C94 (Standard Specification for Ready-Mixed Concrete).

• It is important to con...read more
