Shree Balaji Construction 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.

Minimum setting time of cement is the shortest time required for cement to harden and develop strength.

• Minimum setting time varies depending on the type of cement and environmental conditions.

• For example, ordinary Portland cement typically has a minimum setting time of 30 minutes.

• Factors affecting setting time include temperature, water-cement ratio, and presence of additives.

• Setting time can be tested using Vicat appa

Theodolite is an instrument used in surveying to measure horizontal and vertical angles.

• Theodolite is used to measure angles in both horizontal and vertical planes.

• It consists of a telescope mounted on a base with graduated circles for precise measurements.

• Theodolite is commonly used in construction, mapping, and land surveying.

• Other instruments used in surveying include total stations, levels, and GPS receivers.

Bar Bending Schedule is a document that provides details of reinforcement steel bars used in a construction project.

• It includes details like bar mark, type of bar, diameter, length, shape, and bending dimensions.

• It helps in estimating the quantity of steel required for the project.

• It is essential for ensuring proper reinforcement placement as per structural design.

• Bar Bending Schedule is prepared based on structural dr...read more
