Corrival Corporate Services Interview Questions, Process, and Tips

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

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.

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.

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.

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.

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

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 st...read more

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 ...read more

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 ...read more
