KRAN Consulting Interview Questions and Answers

Nominal mix is a rough estimate of proportions while design mix is a precise mix of ingredients.

• Nominal mix is used for small construction projects while design mix is used for large projects.

• Nominal mix is not as accurate as design mix.

• Nominal mix uses volume batching while design mix uses weight batching.

• Nominal mix is cheaper than design mix.

• Example of nominal mix: 1:2:4 (cement:sand:aggregate)

• Example of design mix: M20 (1:1.5:3) (cement:sand:aggregate)

The density of steel is around 7.85 g/cm³.

• Steel density is the mass per unit volume of steel.

• It is measured in grams per cubic centimeter (g/cm³).

• The density of steel varies depending on its composition and properties.

• The density of mild steel is around 7.85 g/cm³.

• The density of stainless steel is around 7.9 g/cm³.

• The density of high carbon steel is around 7.8 g/cm³.

The number of cement bags in 1 cubic meter varies depending on the density of the cement.

• The density of cement can range from 1440 to 1840 kg/m^3.

• Assuming a density of 1500 kg/m^3, approximately 200 bags of cement would be needed for 1 cubic meter.

• To calculate the exact number of bags, divide the density of the cement by the weight of one bag.

M20 grade is a mix of concrete that has a compressive strength of 20 megapascals (MPa).

• M20 grade is commonly used in construction for residential and commercial buildings.

• It is a mix of 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• The water-cement ratio should be around 0.5 for M20 grade concrete.

• M20 grade concrete is suitable for foundations, beams, and slabs.

• The curing time for M20 grade concrete is around 28 days.

BBS stands for Bar Bending Schedule, which is a document that provides details of reinforcement steel required for a construction project.

• BBS is prepared based on the structural drawings and specifications provided by the client or consultant.

• It includes details such as the diameter and length of each reinforcement bar, the number of bars required, and the shape and size of the bar bends.

• BBS helps in estimating the quantity of steel required for the project and also ensures t...read more

The number of bricks in 1 cubic meter varies depending on the size of the bricks.

• The size of the bricks affects the number of bricks in 1 cubic meter.

• Different brick sizes result in different brick quantities.

• To determine the number of bricks, we need to know the dimensions of the bricks.

TMT stands for Thermo-Mechanically Treated bars, which are high-strength reinforcement bars used in construction.

• TMT bars are made by subjecting mild steel bars to a series of processes involving heat treatment and rapid cooling.

• The resulting bars have a hard outer layer and a soft inner core, making them more resistant to corrosion and fatigue.

• TMT bars are commonly used in reinforced concrete structures, such as buildings, bridges, and dams.

• They are available in various grad...read more

A flow chart for the specific department in a company.

• List all the steps involved in the department's workflow

• Connect the steps with arrows to show the flow of activities

• Include decision points and branches in the flow chart

• End the flow chart with the final outcome or result
