Tractebel Manager Civil Interview Questions and Answers

Power plant cycle is a series of processes that convert fuel into electricity.

• Fuel is burned to produce heat

• Heat is used to boil water and create steam

• Steam turns a turbine which generates electricity

• Excess heat is released into the environment

• Water is cooled and recycled in the system

Casting methods are processes used to create metal objects by pouring molten metal into a mold.

• Sand casting: uses sand molds to create the shape of the object

• Investment casting: uses wax patterns that are melted away to create the mold

• Die casting: uses metal molds to create complex shapes with high accuracy

• Permanent mold casting: uses reusable molds made of metal

• Centrifugal casting: rotates the mold to distribute the m

Batch production is a manufacturing process where products are made in groups or batches, rather than individually.

• Products are produced in specified quantities at a time

• Each batch goes through the whole production process together

• Common in industries like food processing, pharmaceuticals, and automotive manufacturing

Supercritical stage of steam refers to a state where it exhibits properties of both liquid and gas.

• Occurs at temperatures and pressures above the critical point

• Density and viscosity are similar to liquids, while diffusivity and compressibility are similar to gases

• No distinct boundary between liquid and gas phases

• Used in power plants for more efficient energy generation

Concrete temperature refers to the temperature of freshly mixed concrete.

• Concrete temperature affects the setting time and strength development of concrete.

• It is important to control the temperature of concrete during mixing, transportation, and placement.

• High temperatures can accelerate the setting time and reduce workability, while low temperatures can slow down setting and strength gain.

• Concrete temperature is typic...read more

Precocious of water structure joint refers to the ability of a joint to withstand water pressure and prevent leakage.

• Water structure joints should be designed and constructed to be watertight.

• Various types of joints can be used in water structures, such as expansion joints, construction joints, and control joints.

• Proper sealing materials and techniques should be employed to ensure the integrity of the joints.

• Regular in...read more

Cube test results are used to determine the compressive strength of concrete at 7 and 28 days.

• Cube test involves casting cubes of concrete and testing them under compression

• Results are reported in terms of compressive strength in MPa or psi

• 7-day results are used to determine early strength and 28-day results are used to determine ultimate strength

• Concrete with a compressive strength of at least 20 MPa is considered sui
