Cryscon Infra Site Engineer Interview Questions, Process, and Tips

The best soil for a reinforced earth wall is granular soil with good drainage and high shear strength.

• Granular soil provides good drainage and allows for proper compaction.

• High shear strength is necessary to resist lateral pressure from the retained soil.

• Examples of suitable soils include gravel, sand, and crushed rock.

• Clay soils should be avoided due to their poor drainage and low shear strength.

Laying geogrid involves placing a geogrid material in a specific pattern to reinforce soil and prevent erosion.

• Geogrids are typically made of plastic or polyester materials.

• They are placed in a specific pattern to provide reinforcement to soil.

• This method is commonly used in road construction and slope stabilization projects.

• Proper installation is important to ensure the effectiveness of the geogrid.

• The geogrid should ...read more

Pull out test is a test to determine the bond strength between concrete and reinforcement steel.

• It involves applying a tensile force to a steel bar embedded in concrete

• The force required to pull the bar out of the concrete is measured

• The test is used to ensure the strength and safety of concrete structures

• It is also used to evaluate the quality of concrete and the effectiveness of reinforcement

• ASTM C900 specifies the s...read more

RE walls are reinforced earth walls used for retaining soil and providing stability to slopes.

• RE walls are made of alternating layers of compacted soil and reinforcement materials such as geotextiles, geogrids, or steel strips.

• The reinforcement materials provide tensile strength to the soil and prevent it from sliding or collapsing.

• RE walls can be used for a variety of applications such as highway and railway embankmen...read more
