Shiv Construction Site Engineer Interview Questions, Process, and Tips

There is no direct conversion between square feet and cubic meters as they measure different dimensions.

• Square feet (ft²) is a unit of area, while cubic meters (m³) is a unit of volume.

• To convert between the two, you would need to know the height or depth of the space in question.

• For example, if you have a room that is 10 feet wide, 10 feet long, and 10 feet high, the volume would be 1,000 cubic feet (10 ft × 10 ft × 1...read more

The permetric weight of 25mm reinforcement can be found using the formula: weight = (d^2/162) * L, where d is the diameter and L is the length.

• Calculate the square of the diameter of the reinforcement (25mm * 25mm = 625mm^2)

• Divide the square by 162 (625mm^2 / 162 = 3.858mm)

• Multiply the result by the length of the reinforcement to get the permetric weight

The number of bricks used in 1 m³ varies depending on the size of the bricks.

• The size of the bricks affects the number of bricks used in 1 m³.

• Different countries may have different standard brick sizes.

• To calculate the number of bricks, divide the volume of 1 m³ by the volume of a single brick.

• For example, if the size of a brick is 0.2 m x 0.1 m x 0.06 m, the volume of a single brick is 0.0012 m³.

• In this case, the numb...read more

The number 20 in M20 refers to the compressive strength of concrete in megapascals after 28 days of curing.

• M20 is a mix of concrete with a compressive strength of 20 megapascals (MPa) after 28 days of curing.

• The compressive strength of concrete is the maximum amount of compressive stress that the concrete can withstand before failing.

• The strength of concrete is determined by the ratio of cement, sand, and aggregate use...read more

Strength of 28 days refers to the compressive strength of concrete after 28 days of curing.

• It is a measure of the concrete's ability to resist compression.

• It is an important factor in determining the quality of the concrete.

• The strength of concrete can vary depending on the mix design, curing conditions, and other factors.

• The standard for minimum compressive strength of concrete after 28 days is 20 MPa.

• Testing is done ...read more

BBD stands for Babu Banarasi Das, a renowned politician and former Chief Minister of Uttar Pradesh, India.

• BBD is the acronym for Babu Banarasi Das, a prominent political figure in Uttar Pradesh.

• Babu Banarasi Das was the Chief Minister of Uttar Pradesh from 1995 to 1996.

• BBD is also the name of a university in Lucknow, Uttar Pradesh, established in 2010.

For M20 grade, approximately 320 kg of cement is used in 1m³.

• M20 grade concrete has a mix proportion of 1:1.5:3 (cement:sand:aggregate).

• The total volume of the mix is 1+1.5+3 = 5.5

• Therefore, the cement quantity required for 1m³ = (1/5.5) x 1m³ = 0.182m³

• The density of cement = 1440 kg/m³ (approx.)

• Hence, the cement required for 1m³ = 0.182 x 1440 kg/m³ = 262.08 kg/m³ (approx.)

• However, it is recommended to use 320 kg/m³ t

The answer is 0.1818

• The formula is a division operation

• The result is a decimal number

• The answer is recurring
