Shyam Indus Power Solutions Civil Engineer Interview Questions, Process, and Tips

Answers to questions related to civil engineering interview.

• Contraction joints are used to prevent cracking due to shrinkage, while expansion joints allow for the expansion and contraction of concrete.

• Curing is necessary after concreteing to prevent moisture loss, maintain proper hydration, and enhance the strength and durability of the concrete.

• M20 grade of concrete refers to the mix ratio of cement, sand, and aggrega...read more

Good strength in civil engineering can be achieved through proper gating techniques.

• Use high-quality materials for construction

• Ensure proper mixing of concrete and other materials

• Follow proper curing techniques

• Use reinforcement bars and other strengthening methods

• Perform regular maintenance and inspections

• Consider factors such as load capacity and environmental conditions

Concrete grades are classifications that indicate the strength of the concrete mix used in construction.

• Concrete grades are denoted by the letter 'M' followed by a number, such as M20, M30, etc.

• The number after 'M' represents the compressive strength of concrete in N/mm^2 after 28 days of curing.

• Higher grade numbers indicate higher strength concrete, suitable for different types of construction projects.

• For example, M2...read more

Concrete strength typically reaches about 70-80% of its final strength after 7 days.

• Concrete strength gain after 7 days is usually around 70-80% of its final strength

• Factors such as mix design, curing conditions, and type of cement can affect the rate of strength gain

• For example, high early strength concrete may reach higher percentages of its final strength after 7 days compared to normal concrete

Non destructive testing of concrete is a method used to evaluate the properties of concrete without causing damage.

• Methods include ultrasonic testing, rebound hammer, and ground penetrating radar.

• These tests help assess the strength, durability, and quality of concrete structures.

• Non destructive testing is essential for ensuring the safety and longevity of buildings and infrastructure.

• Examples of non destructive testin...read more

Transportation of concrete involves mixing, loading, and delivering the concrete to the construction site.

• Concrete is mixed at a batching plant using cement, sand, gravel, and water.

• The mixed concrete is then loaded into transit mixers or concrete trucks for transportation.

• Transit mixers rotate to prevent the concrete from setting during transportation.

• Concrete pumps can also be used to transport concrete to hard-to-re

Admixtures are used in ready mixed concrete to improve workability, durability, and strength.

• Admixtures help in reducing water content while maintaining workability.

• They enhance the durability of concrete by reducing permeability and increasing resistance to chemicals.

• Admixtures can also accelerate or retard the setting time of concrete.

• Examples of admixtures include water reducers, accelerators, retarders, and air-ent

Equipment used in steam turbine include turbine blades, nozzles, casing, rotor, bearings, and governor.

• Turbine blades: convert steam energy into mechanical energy

• Nozzles: control the flow of steam into the turbine

• Casing: contains and directs the steam flow through the turbine

• Rotor: connected to the turbine blades and rotates to generate power

• Bearings: support the rotor and reduce friction

• Governor: regulates the speed o

Woodward 505 is a versatile control system used in industrial applications.

• The Woodward 505 is a widely used control system in industries such as power generation, oil and gas, and marine.

• It offers advanced features like PID control, sequencing, and communication capabilities.

• The Woodward 505 is known for its reliability and robustness in harsh operating environments.

• It can be easily integrated with various types of se

The Honeywell DCS (Distributed Control System) is a modular system consisting of controllers, I/O modules, and operator stations.

• Consists of controllers, I/O modules, and operator stations

• Uses a network to communicate between components

• Allows for centralized control and monitoring of processes

• Supports various communication protocols such as Modbus, OPC, etc.

• Example: Honeywell Experion PKS

PID stands for Proportional-Integral-Derivative, a control loop feedback mechanism used in engineering.

• PID is a control algorithm that calculates an error value as the difference between a desired setpoint and a measured process variable.

• Proportional (P) control responds to the current error value.

• Integral (I) control accumulates past errors to correct the present error.

• Derivative (D) control predicts future errors bas...read more

To assign a new channel in Honeywell DCS, you need to access the configuration software and follow the steps to add the channel.

• Access the Honeywell DCS configuration software

• Navigate to the channel configuration section

• Add a new channel by specifying the channel number, type, and other relevant parameters

• Save the changes and verify the new channel is successfully assigned

Interlocks and permissives are safety mechanisms in place to prevent unsafe operation of boiler and turbine systems.

• Interlocks prevent certain actions from taking place unless specific conditions are met

• Permissives allow certain actions to take place only if specific conditions are met

• Example of interlock: Boiler feed pump interlock prevents the boiler from starting unless the feed pump is running

• Example of permissive:...read more
