L&T Construction Civil GET Interview Questions and Answers

The thickness of a tile can vary depending on the type and size of the tile being used.

• Tile thickness typically ranges from 1/4 inch to 3/4 inch.

• Larger tiles may have a thicker thickness to support their weight.

• Thin tiles are often used for wall applications, while thicker tiles are used for flooring.

• Porcelain tiles are usually thicker than ceramic tiles.

The thickness of marble can vary depending on the type and purpose, but it is typically between 3/4 inch to 1 1/4 inches.

• Marble thickness can range from 3/4 inch to 1 1/4 inches

• Thicker marble is often used for countertops and flooring

• Thinner marble may be used for wall cladding or decorative purposes

The process of flooring involves selecting the appropriate materials, preparing the subfloor, laying the flooring material, and finishing with trim.

• Selecting the appropriate flooring material based on the location and usage (e.g. hardwood, laminate, tile, carpet)

• Preparing the subfloor by ensuring it is clean, level, and dry

• Laying the flooring material according to manufacturer's instructions, starting from the center o...read more

Types of tiles include ceramic, porcelain, glass, and natural stone. Cement ratio in tile installation varies depending on the type of tile and substrate.

• Types of tiles: ceramic, porcelain, glass, natural stone

• Cement ratio varies based on tile type and substrate

• Ceramic tiles typically require a 1:4 cement to water ratio for installation

• Porcelain tiles may need a 1:3 cement to water ratio for proper adhesion

Flooring process involves selecting materials, preparing the subfloor, installing the flooring, and finishing with trim.

• Selecting appropriate flooring material based on budget, durability, and aesthetics (e.g. hardwood, laminate, tile, carpet)

• Preparing the subfloor by ensuring it is clean, level, and dry before installation

• Installing the flooring by following manufacturer's instructions and using proper tools (e.g. adh...read more

The cement ratio for flooring depends on the type of flooring and the strength required.

• The typical cement ratio for standard concrete flooring is 1:2:4 (cement:sand:aggregate)

• For high strength flooring, the ratio can be increased to 1:1.5:3

• For decorative or polished concrete flooring, a lower water-cement ratio is used to achieve a smoother finish

A beam is a structural element that is designed to resist loads applied perpendicular to its longitudinal axis.

• Beams are commonly used in construction to support loads over a span.

• They can be made of various materials such as wood, steel, or concrete.

• Beams can be classified based on their shape, such as I-beams, H-beams, or T-beams.

• The design of a beam takes into account factors like span length, load requirements, and

King post and queen post are both types of trusses used in construction, with king post being a simpler design and queen post being a more complex design.

• King post is a simple vertical member in a truss, while queen post is a pair of vertical members connected by a horizontal member.

• Queen post trusses are stronger and can span longer distances compared to king post trusses.

• King post trusses are commonly used in small s...read more

The type of steel used in slabs is typically reinforced steel bars, also known as rebar.

• Reinforced steel bars are commonly used in slabs to provide tensile strength and prevent cracking.

• Different grades of steel can be used depending on the structural requirements of the slab.

• Examples of steel types used in slabs include ASTM A615 Grade 60 and ASTM A706 Grade 60 rebar.

Tension is a force that pulls or stretches an object.

• Tension is a type of mechanical stress that occurs when an object is pulled or stretched.

• It is a force that acts in the opposite direction of compression.

• Tension is commonly seen in structures like bridges and cables.

• Examples of tension include a rope being pulled taut or a rubber band being stretched.

Compression is the action of applying pressure to reduce the size or volume of an object or material.

• Compression is a force that squeezes or presses an object or material together.

• It is commonly used in civil engineering to test the strength of materials like concrete or soil.

• Compression can cause materials to deform or break if the force applied is too great.

• Examples of compression include the weight of a building pre...read more
