Sattva Developer Interview Questions and Answers

Q1. What is coloumn lap length
Ans. 
Column lap length is the length of overlap between two reinforcing bars in a column.
• Column lap length is important for ensuring proper structural integrity in a column.

• It is typically specified in construction drawings or codes.

• The lap length is determined based on the diameter of the reinforcing bars and the structural requirements.

• For example, a column may require a lap length of 40 times the diameter of the bar.

Q2. What is 2d, 4d
Ans. 
2D and 4D refer to dimensions in geometry and physics.
• 2D refers to two-dimensional space, like a flat surface with length and width.

• 4D refers to four-dimensional space, which includes the three dimensions of space (length, width, height) and the dimension of time.

• Examples of 2D objects include a square or a circle, while examples of 4D concepts include spacetime in physics.

Q2. How to find triangle concrete quantity.
Ans. 
Triangle concrete quantity can be found using the formula: 1/2 * base * height * thickness.
• Calculate the area of the triangle using the formula: 1/2 * base * height.

• Multiply the area by the thickness to get the concrete quantity.

• For example, if the base of the triangle is 5 meters, height is 8 meters, and thickness is 0.2 meters, the concrete quantity would be: 1/2 * 5 * 8 * 0.2 = 4 cubic meters.

Q3. How to find circular column concrete quantity.
Ans. 
Circular column concrete quantity can be found using the formula: Volume = πr^2h
• Calculate the area of the circular column using the formula A = πr^2

• Measure the height of the column

• Multiply the area by the height to get the volume of concrete needed

• Consider any additional factors such as wastage or reinforcement bars

Q5. What is slump test why we do.
Ans. 
Slump test is a method to measure the consistency of concrete before it sets.
• Slump test is used to determine the workability of fresh concrete.

• It involves filling a cone-shaped mold with concrete, then lifting the mold to see how much the concrete slumps or settles.

• The amount of slump indicates the consistency of the concrete - a higher slump means a more workable mix.

• Slump test helps in ensuring that the concrete mix ...read more

Q6. Compressive strength of concrete after 14 & 28 days and also persentage of strength.
Ans. 
Compressive strength of concrete is typically measured after 14 and 28 days to assess its strength development.
• Compressive strength of concrete is usually measured in pounds per square inch (psi) or megapascals (MPa).

• After 14 days, the average compressive strength of concrete is around 60-75% of its ultimate strength.

• After 28 days, the concrete typically reaches about 90-95% of its ultimate strength.

• The percentage of s...read more

Q7. Mix ratios of concrete
Ans. 
Mix ratios of concrete refer to the proportions of cement, sand, and aggregate used in a concrete mix.
• Mix ratios are typically expressed as a ratio of cement:sand:aggregate, such as 1:2:4.

• The mix ratio will vary depending on the strength and durability requirements of the concrete.

• Common mix ratios include 1:2:3 for low strength concrete and 1:1.5:3 for high strength concrete.

• Water is also added to the mix to achieve t
