Structure Site Engineer Interview Questions and Answers

RCC frame structures use reinforced concrete frames, while load-bearing structures rely on walls to support loads.

• RCC frame structures consist of beams and columns that support the building, allowing for more open spaces.

• Load-bearing structures use walls to support loads, limiting design flexibility and often resulting in smaller openings.

• RCC frames can accommodate taller buildings due to their strength and stability, while load-bearing structures are typically shorter.

Different grades of concrete are used for different purposes, with varying proportions of cement, sand, and aggregates.

• Grades of concrete include M5, M7.5, M10, M15, M20, M25, etc.

• The proportion of cement, sand, and aggregates varies for each grade.

• For example, M20 grade concrete has a mix ratio of 1:1.5:3 (cement:sand:aggregate).

A well foundation is a deep foundation type used to support structures in weak soil by transferring loads to deeper, stable soil layers.

• Well foundations are cylindrical structures, often used in bridge construction.

• They are typically constructed using reinforced concrete.

• Well foundations are effective in areas with high water tables or soft soil.

• An example is the use of well foundations for piers in river crossings.

M25 grade concrete has a compressive strength of 25 megapascals after 28 days of curing.

• M25 grade concrete is a mix of 1 part cement, 1 part fine aggregates, and 2 parts coarse aggregates.

• The compressive strength of M25 grade concrete is typically achieved after 28 days of curing.

• The strength of M25 grade concrete is 25 megapascals, which is suitable for structural applications.
