RPP Infra Projects Site Engineer Interview Questions and Answers

Q1. Cement ka grade
Ans. 
Cement grades indicate the strength and quality of cement, essential for construction projects.
• Cement grades are classified based on their compressive strength, measured in megapascals (MPa).

• Common grades include 33, 43, and 53, with 53 being the highest strength cement.

• Grade 33 is suitable for general construction, while Grade 53 is used for high-strength applications.

• Higher grade cement allows for thinner structures ...read more

Q2. Cancrete M20 retio
Ans. 
M20 concrete mix ratio is 1:1.5:3, indicating 1 part cement, 1.5 parts sand, and 3 parts aggregate by volume.
• M20 concrete is a nominal mix with a characteristic compressive strength of 20 MPa.

• The mix ratio of 1:1.5:3 is commonly used for medium-strength structures.

• For example, in a 1 cubic meter mix, you would use approximately 400 kg of cement, 600 kg of sand, and 1200 kg of aggregate.

• Water-cement ratio is crucial; ty...read more

Q3. What is tha water cement ratio
Ans. 
Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
• Water cement ratio affects the strength and durability of concrete.

• Lower water cement ratio results in stronger concrete but may be difficult to work with.

• Typical water cement ratio ranges from 0.4 to 0.6 for normal strength concrete.

• Excess water can lead to lower strength and durability of concrete.
