Schlumberger Civil Site Engineer Interview Questions and Answers

Q1. Grade of concrete
Ans. 
Grade of concrete refers to the strength of the concrete mix design, typically denoted by a number such as M20 or C30.
• Grade of concrete is determined by the ratio of cement, sand, and aggregates in the mix.

• Higher grade numbers indicate higher strength concrete.

• Common grades include M20, M25, M30, etc. for mix design method and C15, C20, C25, etc. for nominal mix method.

Q1. What is 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 is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The ideal water cement ratio varies depending on the type of concrete mix and its intended use.

• For example, a typical water cement ratio for general purp
