Cendrol Interview Questions, Process, and Tips

Unit weight of RCC is typically around 2400 kg/m^3.

• Unit weight of RCC stands for the density of Reinforced Cement Concrete.

• It is typically around 2400 kg/m^3, but can vary depending on the mix design.

• The unit weight is important for calculating the weight of structures and determining load capacities.

Standard thickness of redbrick is 3 inches.

• Standard thickness of redbrick is typically 3 inches.

• Redbricks can also come in thicknesses of 2.5 inches or 4 inches depending on the manufacturer.

• The thickness of redbrick can vary based on the intended use and building regulations.

Modular ratio of plastering is the ratio of the modulus of elasticity of the material used for plastering to the modulus of elasticity of the material used for masonry.

• Modular ratio is used to determine the thickness of plaster required for a given masonry wall.

• It helps in ensuring that the plastering material is compatible with the masonry material in terms of strength and elasticity.

• For example, if the modular ratio ...read more

Steel quantity calculation formula involves calculating the total weight of steel required for a project.

• Calculate the total weight of steel by multiplying the length, width, and height of the steel member by its density.

• Consider the shape of the steel member (e.g. beam, column, slab) when calculating the quantity of steel needed.

• Take into account any additional factors such as wastage, overlaps, and reinforcements in ...read more

One way slab is supported on two opposite sides while two way slab is supported on all four sides.

• One way slab is designed to span in only one direction, supported on two opposite sides.

• Two way slab is designed to span in both directions, supported on all four sides.

• One way slab is commonly used in corridors, walkways, etc.

• Two way slab is commonly used in large rooms, auditoriums, etc.

Segregation is the separation of particles based on size, shape, density, or other properties in a mixture.

• Segregation can occur in materials like concrete, where larger aggregates settle at the bottom while smaller particles rise to the top.

• It can also happen in granular materials like sand and gravel, where particles of different sizes separate during handling or transport.

• Proper mix design and handling techniques ar...read more
