I appeared for an interview before Dec 2020, where I was asked the following questions.
- Q1. Grades of concrete
- Ans.
Concrete grades indicate the compressive strength and mix proportions, essential for construction quality and durability.
Concrete grades are classified based on their compressive strength, measured in megapascals (MPa).
Common grades include M20 (20 MPa), M25 (25 MPa), and M30 (30 MPa), used for different structural applications.
Higher grades like M40 and M50 are used for high-strength applications, such as bridges and ...
- Q2. Density of sand, cement, steel
- Ans.
Density values for sand, cement, and steel are crucial for construction and engineering calculations.
Density of sand: Typically ranges from 1.44 to 1.60 g/cm³ depending on moisture content and type.
Density of cement: Generally around 1.44 g/cm³ for ordinary Portland cement.
Density of steel: Approximately 7.85 g/cm³, making it much denser than sand and cement.
Example: Knowing the density helps in calculating the weight ...
- Q3. Plastering calculation with material requirement
- Ans.
Plastering calculation involves determining the amount of plaster needed based on surface area and mix ratio.
Calculate the surface area to be plastered (length x height).
Determine the thickness of plaster (typically 12-15 mm for internal walls).
Use the plaster mix ratio (e.g., 1:4 for cement to sand) to calculate material quantities.
Example: For a wall of 10m² and 15mm thickness, volume = 10 x 0.015 = 0.15 m³.
For a 1:4...
