L&T Energy Hydrocarbon Sr.Engineer-Projects Interview Questions, Process, and Tips

The grade of concrete normally used for RCC is M20.

• The grade of concrete for RCC (Reinforced Cement Concrete) is determined based on the design requirements and structural considerations.

• The most commonly used grade of concrete for RCC is M20, which means the concrete mix has a compressive strength of 20 megapascals (MPa) after 28 days of curing.

• Other grades of concrete like M25, M30, M35, etc., can also be used depend...read more

Pre-initiative actions for start piling

• Conduct a geotechnical investigation to assess soil conditions

• Obtain necessary permits and approvals from local authorities

• Develop a detailed piling plan and schedule

• Procure required piling equipment and materials

• Ensure safety measures are in place for workers and surrounding areas

• Prepare the site by clearing any obstacles or debris

• Establish proper communication channels with stak...read more

The duration for deshuttering a beam of span 4 mtr depends on various factors.

• The type of formwork used for shuttering the beam

• The strength of the concrete used

• The ambient temperature and humidity

• The curing process followed

• The complexity of the beam design

• The availability of manpower and equipment

• Typically, deshuttering can take anywhere from 7 to 21 days for a beam of span 4 mtr

To define one way and two way slab, we follow different procedures. For two way slab, reinforcement is fixed in both directions.

• One way slab is defined as the slab in which the ratio of longer span to shorter span is greater than or equal to 2.

• Two way slab is defined as the slab in which the ratio of longer span to shorter span is less than 2.

• For two way slab, reinforcement is fixed in both directions to distribute the...read more
