10+ INCO Group Of Companies Interview Questions and Answers
Q1. What type of admixture used in concrete?
Admixtures are chemicals added to concrete to enhance its properties or performance.
Admixtures can improve workability, durability, strength, and set time of concrete.
Examples of admixtures include water reducers, accelerators, retarders, and air-entraining agents.
Q2. What is cube casting frequency Ans 0 -5 m3 1 set
Cube casting frequency refers to the number of times concrete cubes are cast for testing purposes.
Cube casting frequency is determined by the project requirements and specifications.
It is important to cast an adequate number of cubes to ensure accurate testing results.
Typically, cube casting frequency ranges from 0 to 5 cubic meters per set.
For example, if the project requires testing of 10 cubic meters of concrete, two sets of cubes may be cast.
The cubes are then cured and t...read more
Q3. What is cube acceptance criteria?
Cube acceptance criteria refers to the set of standards or requirements that a cube must meet in order to be accepted or approved.
Cube dimensions must meet specified tolerances
Surface finish must meet specified standards
Cube must pass specified strength or durability tests
Cube must meet any other specified criteria for acceptance
Q4. What is workability of concrete?
Workability of concrete refers to its ease of mixing, placing, and compacting without segregation or bleeding.
Workability is influenced by water content, aggregate size and shape, and admixtures.
Concrete with high workability is easier to place and compact, while low workability may require more effort.
Examples of tests to measure workability include slump test, flow table test, and Vebé test.
Q5. What is code for UPV test?
The code for UPV test is ASTM C597.
ASTM C597 is the standard code for Ultrasonic Pulse Velocity (UPV) test.
UPV test is commonly used in construction to assess the quality of concrete.
The test involves sending ultrasonic pulses through the concrete and measuring the time taken for the pulses to travel through the material.
Q6. What is slump cone test layer
The slump cone test measures the consistency and workability of fresh concrete.
The slump cone test is a standard test used in the construction industry.
It measures the consistency and workability of fresh concrete.
A slump cone is a mold in the shape of a truncated cone.
The test involves filling the cone with fresh concrete, compacting it, and then removing the cone to measure the slump or settlement of the concrete.
The slump value indicates the flow and cohesiveness of the co...read more
Q7. Name the different types of pile.
Different types of pile include friction piles, end-bearing piles, and composite piles.
Friction piles rely on skin friction along the length of the pile for support.
End-bearing piles transfer the load to a strong layer of soil or rock at the bottom.
Composite piles combine different materials like concrete and steel for added strength.
Other types include sheet piles, helical piles, and screw piles.
Q8. What stands for M30?
M30 stands for a metric thread size commonly used in engineering and manufacturing.
M30 refers to a metric thread size with a diameter of 30mm
It is commonly used in engineering and manufacturing for fastening components
Examples of M30 fasteners include bolts, screws, and nuts
Q9. What is a motor and starter.
A motor is an electrical device that converts electrical energy into mechanical energy, while a starter is a device that starts the motor.
A motor consists of a rotor and a stator, which work together to produce rotational motion.
Motors are used in a wide range of applications, from powering industrial machinery to driving electric vehicles.
A starter is typically used to provide the initial burst of power needed to get a motor running.
Starters can take many forms, including ma...read more
Q10. What are the IS CODE for billing & concrete
IS codes for billing & concrete in construction industry
IS 456:2000 - Code of practice for plain and reinforced concrete
IS 3370:1965 - Code of practice for concrete construction
IS 1786:2008 - High strength deformed steel bars and wires for concrete reinforcement
IS 4985:2000 - PVC pipes for potable water supplies
Q11. What is a transformer
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, known as the primary and secondary windings, wrapped around a magnetic core.
When an AC voltage is applied to the primary winding, it creates a magnetic field that induces a voltage in the secondary winding.
Tran...read more
Q12. What are the procedures for billing.
Procedures for billing involve preparing invoices, verifying accuracy, sending to clients, and following up on payments.
Prepare detailed invoices based on project scope and work completed
Verify accuracy of billing information, including rates, quantities, and discounts
Send invoices to clients through email or mail
Follow up on payments and resolve any billing discrepancies
Maintain records of all billing transactions for future reference
Q13. Codes and Standards related to welding
Various codes and standards govern welding processes to ensure quality and safety.
American Welding Society (AWS) codes such as AWS D1.1 for structural welding
American Society of Mechanical Engineers (ASME) codes such as ASME Section IX for boiler and pressure vessel welding
International Organization for Standardization (ISO) standards like ISO 9606 for qualification of welders
European Standard EN 1090 for structural steel and aluminum welding
National Fire Protection Associati...read more
