Desire Energy Solution Project Coordinator Interview Questions, Process, and Tips

Q1. What is the characteristic compressive strength of concrete.
Ans. 
The characteristic compressive strength of concrete is the strength of concrete at 28 days of curing.
• It is the strength of concrete after 28 days of curing

• It is the strength at which the concrete can bear the maximum load without failure

• It is determined by testing a sample of concrete in a compression testing machine

• The characteristic compressive strength is used to design concrete structures

• For example, if the charact...read more

Q2. How can we conduct the sieve analysis of sand & Agreegate.
Ans. 
Sieve analysis of sand & aggregate is conducted to determine the particle size distribution.
• Collect a representative sample of sand or aggregate.

• Weigh the sample and record the weight.

• Prepare a series of sieves with different mesh sizes.

• Stack the sieves in ascending order of mesh size, with the finest sieve at the bottom.

• Place the sample on the top sieve and cover it with a lid.

• Shake the sieves manually or using a mech...read more

Q3. What is the exact height of falling of concrete as per is IS 456: 2000
Ans. 
The exact height of falling of concrete is not specified in IS 456: 2000.
• IS 456: 2000 does not provide a specific height for the falling of concrete.

• The standard focuses on the design and construction requirements for reinforced concrete structures.

• It covers aspects such as materials, mix proportions, workmanship, and quality control.

• The height of falling concrete may be specified in project-specific specifications or ...read more

Q4. What is the slump value of mass concreting
Ans. 
The slump value of mass concreting refers to the measure of consistency or workability of the concrete mixture.
• Slump value is determined by conducting a slump test on freshly mixed concrete.

• It indicates the flow and compactability of the concrete.

• The slump value is measured in millimeters and can range from 0 to 200 mm.

• Higher slump values indicate a more fluid and workable concrete mixture.

• Lower slump values indicate a...read more

Q5. How can we conduct concrete cube test.
Ans. 
Concrete cube test is conducted to measure the compressive strength of concrete.
• Prepare the concrete cubes by using a standard mix design.

• Fill the cube moulds with freshly mixed concrete in layers.

• Compact the concrete using a vibrating table or a vibrating poker.

• Smooth the surface of the cubes using a trowel.

• Label each cube with relevant information like date, mix design, etc.

• Cure the cubes in a curing tank or moist en...read more
