Apco Infratech Civil Engineer Interview Questions and Answers

Grades of concrete in a mixed batch can be estimated by performing a slump test and conducting compressive strength tests on samples.

• Perform a slump test to determine the workability of the concrete mix.

• Take samples from the mixed batch and cast test specimens for compressive strength testing.

• Conduct compressive strength tests on the specimens to determine the grade of concrete.

• Compare the test results with the standar

Site and laboratory tests on bricks and cement are essential for ensuring quality and durability of construction materials.

• Site tests for bricks include visual inspection, water absorption test, compressive strength test, and efflorescence test.

• Laboratory tests for bricks involve water absorption test, compressive strength test, efflorescence test, and soundness test.

• Site tests for cement include checking the color, sm...read more

Plastering work calculation involves determining the surface area of the wall and the thickness of the plaster.

• Calculate the surface area of the wall by multiplying the height and length of each wall segment.

• Determine the total surface area to be plastered by adding up the surface areas of all wall segments.

• Multiply the total surface area by the desired thickness of the plaster to get the volume of plaster needed.

• Consi...read more
