Hi Tech Projects Civil Engineer Interview Questions, Process, and Tips

Minimum diameter of bar used in column is determined by structural requirements and load calculations.

• Minimum diameter is typically specified in the structural design drawings or calculations

• Factors such as column height, load capacity, and seismic considerations influence the minimum bar diameter

• Common minimum diameters for column bars range from 12mm to 25mm depending on the structural requirements

Minimum grade of concrete used in column is typically M20.

• Minimum grade of concrete used in column is usually M20

• Higher grades like M25, M30, M35, etc. can also be used for columns based on structural requirements

• The grade of concrete is determined based on the strength required for the structure

Minimum thickness of slab is determined based on factors like load, span, and material used.

• Minimum thickness of slab is typically determined by structural engineers based on the expected loads and span of the slab.

• Factors such as the material used for the slab and any additional reinforcement also play a role in determining the minimum thickness.

• For example, a residential slab may have a minimum thickness of 4 inches,...read more

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 typical water cement ratio for general purp

The density of steel is approximately 7.85 g/cm^3.

• The density of steel is commonly expressed in grams per cubic centimeter (g/cm^3).

• The density of steel can vary slightly depending on the specific alloy and composition.

• For example, the density of stainless steel is around 7.9 g/cm^3, while carbon steel is around 7.85 g/cm^3.
