Congruex Asia Pacific Engineering Assistant Interview Questions and Answers

The percentage of steel in a pile varies depending on the type and design of the pile.

• The percentage of steel in a pile can range from 0% to over 90%.

• The type of pile (e.g. steel, concrete, timber) and its design (e.g. diameter, length, wall thickness) determine the percentage of steel.

• Steel piles typically have a higher percentage of steel than other types of piles.

• The percentage of steel in a pile can also affect its...read more

Pile built-up above cut off level as per IS code

• IS code specifies the maximum allowable pile length above cut off level

• Pile length above cut off level should not exceed 3 times the pile diameter

• Built-up pile above cut off level can cause structural instability and failure

Vertical tolerance for piles as per IS code

• As per IS 2911-1:2010, the vertical tolerance for piles is +/- 25mm

• This tolerance is applicable for both driven and cast-in-situ piles

• The tolerance is measured at the top of the pile and at intervals of 3m along the length

• If the deviation exceeds the tolerance limit, the pile may need to be rejected or remedial measures taken

Pile concrete consumption tolerance depends on various factors.

• Pile diameter and length

• Concrete mix design

• Placement method

• Quality control measures

• Environmental conditions

• Tolerance typically ranges from 5-10% of estimated consumption

• Regular monitoring and adjustment of concrete consumption is necessary

Unit weight of steel is 7850 kg/m³

• The unit weight of steel is the weight of a specific volume of steel

• It is measured in kilograms per cubic meter (kg/m³)

• The unit weight of steel is 7850 kg/m³

• This value may vary slightly depending on the composition and manufacturing process of the steel

Various types of cement include Portland cement, white cement, rapid hardening cement, and low heat cement.

• Portland cement is the most commonly used type of cement in construction.

• White cement is used for decorative purposes and has a high degree of whiteness.

• Rapid hardening cement is used in situations where quick setting is required.

• Low heat cement is used in large concrete structures to prevent excessive heat genera...read more

IS 456:2000 outlines basic rules and regulations for reinforced concrete design and construction.

• The code specifies the minimum grade of concrete to be used for different types of structures.

• It provides guidelines for the minimum thickness of concrete cover over reinforcement.

• The code also outlines the maximum permissible stresses for different grades of steel.

• It specifies the minimum reinforcement required for differe...read more
