SBR Group Interview Questions, Process, and Tips

The size of a solid concrete block can vary depending on its intended use and manufacturer.

• Standard sizes for solid concrete blocks are 8x8x16 inches or 4x8x16 inches

• Blocks can also be custom made to specific dimensions

• Size may also vary based on the type of construction project

A section of beam and slab typically consists of a horizontal slab supported by vertical beams. The depth of the beam is determined based on structural requirements.

• The beam is typically deeper than the slab to provide adequate strength and support

• The depth of the beam is determined based on factors such as span length, load requirements, and structural design

• Reinforcement bars are often used in both the beam and slab

Tiles are commonly used for flooring and wall covering, available in various materials and designs.

• Ceramic tiles: most common type, made from clay and minerals, durable and easy to clean

• Porcelain tiles: similar to ceramic but denser and less porous, suitable for high traffic areas

• Natural stone tiles: includes marble, granite, limestone, and travertine, offer unique patterns and textures

• Glass tiles: modern and stylish o...read more

The rectification process for hollow laid tiles involves removing the hollow tiles, cleaning the surface, applying fresh adhesive, and re-laying the tiles.

• Identify the hollow tiles by tapping them with a rubber mallet.

• Carefully remove the hollow tiles without damaging the surrounding tiles.

• Clean the surface thoroughly to remove any adhesive residue.

• Apply fresh adhesive to the cleaned surface.

• Re-lay the tiles ensuring t...read more

HT fuse is thin because it is designed to handle high voltage, while LT fuse is fat because it is designed to handle high current.

• HT fuse is designed to handle high voltage, so it needs to be thin to prevent arcing.

• LT fuse is designed to handle high current, so it needs to be fat to handle the flow of electricity.

• Different types of fuses are designed for specific voltage and current ratings.

• Example: HT fuse may be used...read more

PT slab stands for post-tensioned slab, a type of concrete slab reinforced with high-strength steel tendons.

• PT slab is a type of concrete slab that uses high-strength steel tendons to apply compression after the concrete has hardened.

• The tendons are placed in ducts or sleeves within the concrete slab and then tensioned to provide additional strength and reduce cracking.

• PT slabs are commonly used in large span structure...read more

RMC pouring time refers to the duration it takes to pour ready-mix concrete at a construction site.

• RMC pouring time can vary depending on factors such as the volume of concrete needed, the distance from the mixing plant to the site, and the complexity of the project.

• Typically, RMC pouring time ranges from a few hours to a full day for larger projects.

• Efficient planning and coordination are essential to ensure that the ...read more
