Sikaria Group of Companies Interview Questions, Process, and Tips

Development length is the length of reinforcement required to transfer the stress from steel to concrete.

• It is the minimum length of reinforcement bar required to be embedded in concrete to develop the desired bond strength between the two materials.

• It is influenced by the diameter of the bar, the grade of steel, the concrete strength, and the environmental conditions.

• It is calculated using empirical formulas or tables...read more

Lap length refers to the amount of overlap between two reinforcing bars in concrete construction.

• Lap length is important for ensuring the transfer of load between the bars.

• It is specified in construction codes and standards.

• The lap length depends on the diameter of the bars and the type of structure.

• For example, in a beam, the lap length may be 40 times the diameter of the bar.

• Proper lap length is crucial for maintaini

A spacer bar is a component used in construction to maintain a specific distance between two objects.

• Spacer bars are commonly used in reinforced concrete structures to ensure the correct spacing between reinforcing bars.

• They are also used in glass windows to maintain the gap between the panes of glass.

• Spacer bars can be made of various materials such as steel, plastic, or aluminum.

• In civil engineering, spacer bars are ...read more

An estimate is an approximation of the probable cost of a project based on available information.

• Estimate is a prediction of the cost of a project.

• It is based on available information such as design, materials, and labor.

• Estimates can be preliminary or detailed.

• They are used to determine the feasibility of a project and to create a budget.

• Estimates can be revised as more information becomes available.

Nominal cover is the specified amount of concrete cover over the reinforcement bars in a structure.

• Nominal cover is important for protecting the reinforcement from corrosion and ensuring the durability of the structure.

• It is specified in the design of the structure and varies depending on the type of structure and the environmental conditions.

• For example, the nominal cover for a reinforced concrete column in a coastal ...read more

Efflorescence is a white powdery substance that forms on the surface of concrete or masonry due to the presence of soluble salts.

• Occurs when water evaporates from the surface of concrete or masonry

• Leaves behind salt deposits that form a white powdery substance

• Can weaken the surface of the material over time

• Can be prevented by using proper construction techniques and materials

• Commonly seen on basement walls, chimneys, a

Setting time of cement refers to the time taken for the cement to harden and gain strength.

• Setting time is an important property of cement as it determines the workability and handling time of concrete.

• It is influenced by factors such as cement composition, fineness, water-cement ratio, temperature, and admixtures.

• The initial setting time is the time taken for the cement to stiffen and resist penetration by a standard ...read more
