Sfc Infratech Interview Questions, Process, and Tips

Yes, soil testing is a crucial process in civil engineering to assess the properties and suitability of soil for construction projects.

• Soil testing helps determine the soil's composition, strength, and stability.

• It involves collecting soil samples and conducting various tests, such as moisture content, compaction, permeability, and shear strength.

• The results of soil testing guide engineers in designing foundations, ear...read more

Aggregate grading is the process of determining the particle size distribution of aggregates used in construction.

• Aggregate grading is done by performing a sieve analysis.

• The aggregates are passed through a series of sieves with different mesh sizes.

• The retained amount on each sieve is weighed and expressed as a percentage of the total sample weight.

• The grading curve is then plotted using the percentage passing through...read more

RL stands for Reduced Level and it is a term used in civil engineering to refer to the vertical distance between a point and a reference level.

• RL is used to determine the elevation or height of a point in relation to a known reference level.

• It is commonly used in surveying and construction to establish the levels of different points on a site.

• RL can be determined using various methods such as differential leveling, tri...read more

There are three types of benchmarks in civil engineering: primary, secondary, and tertiary.

• Primary benchmarks are permanent reference points with known elevations.

• Secondary benchmarks are temporary points established for a specific project.

• Tertiary benchmarks are intermediate points used for leveling between primary and secondary benchmarks.

• Examples of primary benchmarks include survey monuments and geodetic control po...read more

M 20 is a designation for a concrete mix with a compressive strength of 20 megapascals (MPa).

• M 20 refers to the grade of concrete used in construction projects.

• The number 20 represents the compressive strength of the concrete mix in megapascals.

• The value of 20 is determined based on the requirements of the project and the structural design.

• Different grades of concrete, such as M 10, M 15, M 25, etc., have different com...read more
