Delco Infrastructure Projects Civil Site Engineer Interview Questions and Answers

Cement is a binding material used in construction to hold together bricks, stones, and other materials. Sand is a fine aggregate used in concrete mixes.

• Cement is a powdery substance made from limestone and clay, which when mixed with water forms a paste that hardens to bind materials together.

• Sand is a granular material composed of finely divided rock and mineral particles, commonly used as a fine aggregate in concrete...read more

Aggregate and sand are materials commonly used in construction for creating concrete and mortar.

• Aggregate is a mixture of sand, gravel, crushed stone, or other materials used in construction.

• Sand is a granular material composed of finely divided rock and mineral particles.

• Aggregate is used in concrete to provide bulk and strength, while sand is used in mortar for bonding materials together.

• Examples of aggregate include...read more

The quantity of cement in M25 grade concrete is 350 kg/m³.

• M25 grade concrete has a mix proportion of 1:1:2 (cement:sand:aggregate).

• The total volume of concrete is taken as 1 m³.

• Therefore, the quantity of cement required for 1 m³ of M25 grade concrete is 350 kg.

• This is calculated by multiplying the volume of concrete by the proportion of cement in the mix.

The weight of steel varies with its diameter.

• The weight of steel can be calculated using the formula: weight = volume x density

• The density of steel is approximately 7850 kg/m³

• The volume of steel can be calculated using the formula: volume = pi x (diameter/2)² x length

• For example, a 10mm diameter steel rod with a length of 1 meter would weigh approximately 0.393 kg

Waterproofing is the process of making a structure or object resistant to water penetration.

• Identify the areas that need waterproofing such as roofs, walls, and foundations.

• Clean and prepare the surface to be waterproofed.

• Apply a waterproofing membrane or coating such as bituminous, acrylic, or polyurethane.

• Ensure proper drainage and slope to prevent water accumulation.

• Test the waterproofing system for leaks and make n...read more

Conversion of brass to Cum

• Brass is an alloy of copper and zinc, while Cum is not a known substance

• It is not possible to convert brass to Cum

• Perhaps the question is referring to a different substance or material

The typical slab cycle duration varies depending on the type of slab and construction method.

• Slab cycle duration can range from a few days to several weeks.

• Factors that affect the duration include the type of concrete used, curing time, and weather conditions.

• For example, a typical cycle for a post-tensioned slab may take around 14 days, while a conventionally reinforced slab may take around 21 days.

• During this time, t...read more

Compressive strength is the ability of a material to withstand loads that reduce the size of the material without undergoing any deformation.

• Compressive strength is a measure of the maximum load a material can withstand under compression before failure.

• It is an important property in construction materials like concrete, masonry, and rock.

• Compressive strength is typically measured in units of force per unit area, such a...read more

Density of steel is approximately 7850 kg/m^3.

• Density of steel is typically around 7850 kg/m^3.

• The density of steel can vary slightly depending on the specific alloy.

• Density is an important factor in determining the weight of steel structures.

Curing of columns typically takes 7 days.

• Columns generally require 7 days of curing to achieve the desired strength.

• Curing helps in reducing cracks and increasing the durability of the concrete.

• Proper curing is essential for the long-term performance of the column.

• Factors like temperature, humidity, and type of concrete used can affect the curing time.
