Ashiana Housing Senior Civil Supervisor Interview Questions and Answers

Q1. How to check concrete slump
Ans. 
Concrete slump can be checked using a slump cone and measuring the difference in height before and after filling with concrete.
• Prepare the slump cone by wetting it and placing it on a flat, level surface.

• Fill the cone with concrete in three layers, each tamped with a rod 25 times.

• Lift the cone vertically and measure the difference in height between the top of the cone and the displaced concrete.

• The slump value is the d...read more

Q2. How to check concrete cube
Ans. 
To check concrete cube, perform a compression test to determine the strength of the concrete.
• Perform a compression test on the concrete cube using a compression testing machine.

• Calculate the compressive strength of the concrete cube by dividing the maximum load applied to the cube by the cross-sectional area of the cube.

• Compare the compressive strength of the concrete cube with the specified strength in the design mix ...read more

Q1. How many Concrete blocks is required for 100sft ?
Ans. 
The number of concrete blocks required for 100sft depends on the size of the blocks and the thickness of the wall being built.
• The number of concrete blocks needed can be calculated by dividing the total area (100sft) by the area of one block.

• The size of the concrete block and the thickness of the wall will determine the number of blocks needed.

• For example, if each concrete block is 1ft x 1ft and the wall is 4 inches th

Q2. What is Concrete density?
Ans. 
Concrete density is the mass per unit volume of concrete.
• Concrete density is typically measured in kilograms per cubic meter (kg/m^3).

• The density of normal concrete is around 2400 kg/m^3.

• Higher density concrete, such as heavyweight concrete, can have densities up to 4000 kg/m^3.

• Lightweight concrete, on the other hand, can have densities as low as 1600 kg/m^3.
