Egis India Consulting Engineers Assistant Civil Executive Engineer Interview Questions and Answers

Hydraulic refers to the study of fluids in motion and the engineering applications of fluid mechanics.

• Hydraulic engineering involves the design and construction of structures that control the flow and pressure of liquids, such as dams, canals, and pipelines.

• Hydraulic systems use fluid pressure to generate, control, and transmit power, commonly found in machinery like hydraulic lifts and brakes.

• Hydraulic principles are ...read more

Earthquake loads are calculated using seismic design codes and formulas based on the seismic hazard of the region.

• Determine the seismic hazard of the region using historical data and seismic maps

• Select a seismic design code such as ASCE 7 or Eurocode 8

• Calculate the seismic base shear using the formula V = CsW

• Distribute the seismic base shear to the structure using the appropriate load combinations

• Consider the effects o...read more

Hydration process is the chemical reaction between cement and water which results in the hardening of concrete.

• Hydration process starts as soon as water is added to cement.

• The reaction produces heat and causes the mixture to harden and gain strength.

• The process continues for weeks and even months, resulting in a stronger and more durable concrete.

• The amount of water used in the mixture affects the hydration process and...read more

Concrete strength depends on various factors.

• Water-cement ratio

• Type and quality of cement

• Aggregate size and shape

• Curing conditions

• Mix design

• Age of concrete

• Temperature and humidity

• Presence of admixtures

Water is added to concrete mixer to make the mixture more workable and to achieve the desired consistency.

• Water is added to hydrate the cement and activate the chemical reaction that causes it to harden

• The amount of water added affects the strength and durability of the concrete

• Too much water can weaken the concrete and cause cracking

• The water should be added gradually and mixed thoroughly to ensure even distribution

• Ot...read more

Slump test is a measure of the consistency of fresh concrete.

• It is used to determine the workability of concrete.

• A slump cone is filled with fresh concrete and then lifted vertically.

• The amount of slump or settlement of the concrete is measured.

• The test helps to ensure that the concrete is of the right consistency for the job.

• The slump test is widely used in construction projects.

Grade of concrete and cement are important factors in construction.

• Grade of concrete refers to its strength and durability.

• Grade of cement refers to its compressive strength.

• Concrete grades range from M5 to M80.

• Cement grades include 33, 43, and 53.

• Higher grades of cement are used for stronger concrete.

There are different types of cement used in construction depending on the requirements.

• Ordinary Portland Cement (OPC) is the most commonly used cement.

• Portland Pozzolana Cement (PPC) is used for structures exposed to sulphate and chloride attacks.

• Rapid Hardening Cement (RHC) is used for precast concrete work.

• Low Heat Cement (LHC) is used for massive concrete structures.

• White Cement is used for decorative purposes.

• Color...read more
