Zetwerk Junior Engineer Civil Interview Questions, Process, and Tips

Calculating steel requirement for a 1m span with 100 c/c spacing involves understanding reinforcement needs.

• Determine the type of structure (beam, slab, etc.) to assess steel requirements.

• For beams, typically use 0.5% to 1% of the cross-sectional area for steel reinforcement.

• Example: For a beam with a cross-section of 300mm x 600mm, the area is 0.18 m². Steel required = 0.5% of 0.18 = 0.0009 m².

• Spacing of 100 c/c means...read more

Mix grade ratio of concrete refers to the proportion of cement, sand, and aggregate used in the concrete mix.

• The mix grade ratio of concrete is expressed as the proportion of cement to sand to aggregate.

• The most common mix grade ratios for concrete are 1:2:3 and 1:3:6.

• The mix grade ratio of concrete depends on the strength and durability required for the specific project.

• The mix grade ratio of concrete can be adjusted ...read more

Cube test is performed to determine the compressive strength of concrete.

• Prepare the cube moulds of size 150mm x 150mm x 150mm.

• Clean the moulds and apply oil to the inner surface.

• Fill the moulds with concrete in three layers and compact each layer.

• Level the top surface and cover the moulds with a gunny bag.

• After 24 hours, remove the moulds and immerse the cubes in water for curing.

• After 7 days, test the cubes for compr...read more
