Larsen & Toubro Limited Interview Questions, Process, and Tips for Experienced

Beam reinforcement can be checked by visually inspecting the placement, size, and spacing of the steel bars within the beam.

• Visually inspect the placement of steel bars within the beam to ensure they are in the correct position as per the design drawings.

• Check the size of the steel bars to ensure they meet the specifications outlined in the structural drawings.

• Verify the spacing between the steel bars to ensure they ar...read more

The minimum diameter of rebar for a column depends on the structural design and load requirements.

• The minimum diameter of rebar for a column is typically specified in the structural drawings or design documents.

• Common minimum diameters for column rebars range from 12mm to 25mm, depending on the size and load-bearing capacity of the column.

• The minimum diameter of rebar is important for ensuring the structural integrity ...read more

Cover of reinforcement of slab refers to the distance between the outer surface of the concrete and the reinforcement bars.

• The cover of reinforcement is important for protecting the reinforcement from corrosion and ensuring structural integrity.

• The typical cover of reinforcement for slabs is around 20-30mm, but it can vary depending on the design requirements.

• Factors such as exposure conditions, concrete quality, and l...read more

Concrete quantity can be calculated by multiplying the volume of the area to be filled by the density of the concrete.

• Calculate the volume of the area to be filled (length x width x height)

• Determine the density of the concrete (usually around 2400 kg/m^3)

• Multiply the volume by the density to get the total concrete quantity needed

• Consider adding a percentage for wastage or spillage

There are various types of brick joints used in construction, such as flush joint, raked joint, weathered joint, and v-joint.

• Flush joint is a joint where the mortar is flush with the face of the brick.

• Raked joint is a joint where the mortar is recessed slightly from the face of the brick.

• Weathered joint is a joint where the mortar is sloped to allow water to run off.

• V-joint is a joint where the mortar is shaped like a

There are various types of bricks used in construction, such as clay bricks, concrete bricks, and fire bricks.

• Clay bricks are made from clay and are commonly used for construction.

• Concrete bricks are made from concrete and are known for their strength and durability.

• Fire bricks are made to withstand high temperatures and are used in fireplaces and kilns.

Pressure vessel design involves the calculation of stresses, material selection, and safety factors to ensure the vessel can safely contain the desired pressure.

• Consider the material properties and thickness to withstand the internal pressure

• Calculate stresses using formulas like the thin-walled pressure vessel equation

• Factor in safety margins to account for uncertainties in material properties or loading conditions
