Blue Chip Technologies Site Supervisor Interview Questions and Answers for Freshers

Q1. What is cement grade?
Ans. 
Cement grade refers to the strength and quality of cement used in construction.
• Cement grade is determined by the compressive strength of cement mortar cubes after 28 days of curing.

• The most commonly used cement grades are 33, 43, and 53, indicating their respective compressive strengths in megapascals (MPa).

• Higher cement grades are used for structures that require higher strength, such as bridges and high-rise building...read more

Q3. The standard size of a concrete cube is 15 cm × 15 cm × 15 cm
Ans. 
Yes, the standard size of a concrete cube is 15 cm × 15 cm × 15 cm.
• The standard size of a concrete cube is used for testing the compressive strength of concrete.

• The cubes are casted and cured for 28 days before testing.

• The cubes are tested using a compression testing machine.

• The compressive strength of concrete is calculated by dividing the maximum load applied to the cube by the cross-sectional area of the cube.

Q1. What is the curing on site engineering
Ans. 
Curing is the process of maintaining moisture and temperature conditions for freshly placed concrete to promote its hydration and strength gain.
• Curing is essential for the strength and durability of concrete.

• It involves keeping the concrete moist and at a proper temperature for a specific period of time.

• Curing can be done using various methods such as water curing, membrane curing, and steam curing.

• The duration of curi...read more

Q2. What is the strength of cement
Ans. 
The strength of cement depends on its grade and type.
• The strength of cement is measured in terms of compressive strength.

• The grade of cement determines its strength. Higher the grade, higher the strength.

• Type of cement also affects its strength. For example, Portland cement has higher strength than lime cement.

• The strength of cement is also influenced by factors such as curing time, temperature, and humidity.
