Larsen & Toubro Limited Senior Civil Site Engineer Interview Questions, Process, and Tips

The weight of steel bars can be calculated by multiplying the volume of the steel bar by its density.

• Calculate the volume of the steel bar by using the formula: Volume = (π * (Diameter)^2 * Length) / 4

• Determine the density of the specific type of steel being used

• Multiply the volume by the density to get the weight of the steel bar

Workability refers to the ease and ability of a material to be worked with and manipulated during construction.

• Workability is important in construction as it affects the ease of placing, compacting, and finishing concrete or other materials.

• Factors affecting workability include water content, aggregate size and shape, temperature, and admixtures.

• For example, a concrete mix with high workability will flow easily into fo...read more

Bar bending schedule is a document detailing the shape, quantity, length, and bending dimensions of steel bars used in construction.

• It is prepared by civil engineers to ensure proper placement and bending of reinforcement bars in concrete structures.

• Includes details such as bar mark, diameter, number of bars, length, shape codes, and bending dimensions.

• Helps in estimating the quantity of steel required for construction...read more

The density of steel bars is approximately 7850 kg/m^3.

• The density of steel bars is typically around 7850 kg/m^3.

• Density can vary slightly depending on the specific type of steel used.

• Density is a measure of mass per unit volume.

The mix ratio of grade M20 concrete is 1:1.5:3 (cement:sand:aggregate).

• Grade M20 concrete has a mix ratio of 1:1.5:3 (cement:sand:aggregate).

• This means for every 1 part of cement, 1.5 parts of sand and 3 parts of aggregate are used.

• For example, for a 1 cubic meter of M20 concrete, 0.5 cubic meters of sand and 1.5 cubic meters of aggregate are used.
