Shree Gautam Construction Company Civil Site Engineer Interview Questions and Answers

To start OFC cable blowing, follow these steps

• Ensure that the ducts are clean and free of any obstruction

• Attach the cable blowing machine to the duct

• Connect the cable to the machine and start the blowing process

• Monitor the cable's progress and adjust the machine's speed as needed

• Once the cable has been blown through the entire length of the duct, detach the machine and cable

Penetration test is a method of evaluating the security of a computer system or network by simulating an attack from a malicious source.

• Penetration test involves identifying vulnerabilities in a system or network.

• It includes attempting to exploit these vulnerabilities to determine the potential impact of a real attack.

• The goal of a penetration test is to strengthen the security defenses of the system or network.

• Common ...read more

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

• Waterproofing involves applying materials or coatings to prevent water from seeping through surfaces.

• It is commonly used in construction to protect buildings from water damage.

• Examples of waterproofing materials include bituminous coatings, cementitious waterproofing, and liquid membrane systems.

Types of foundation include shallow, deep, and pile foundations.

• Shallow foundations are used when the soil is strong enough to support the structure's weight, such as spread footings and mat foundations.

• Deep foundations are used when the soil is weak and unable to support the structure's weight, such as pile foundations and drilled piers.

• Pile foundations are deep foundations that consist of long, slender columns driven...read more

Mix design is the process of determining the proportions of cement, water, aggregates, and admixtures in concrete to achieve desired properties.

• Determine the required strength and durability of the concrete

• Select suitable materials such as cement, aggregates, water, and admixtures

• Calculate the proportions of each material based on desired properties and specifications

• Perform trial mixes to test the properties of the co...read more

The weight of green concrete varies depending on the mix design and components used.

• The weight of green concrete typically ranges from 140 to 150 pounds per cubic foot.

• Factors such as the type and amount of aggregates, cement, water, and admixtures used can affect the weight.

• Lightweight concrete can have a lower weight, while high-density concrete can be heavier.

• The weight of green concrete is important for structural

The formula for tensile strength of concrete is based on the cross-sectional area and maximum load applied.

• Tensile Strength = Maximum Load / Cross-sectional Area

• The units for tensile strength are typically in MPa (megapascals)

• Tensile strength is an important property of concrete for determining its ability to resist tension forces

• For example, if a concrete specimen with a cross-sectional area of 100 square millimeters ...read more

The water cement ratio of concrete refers to the ratio of the weight of water to the weight of cement used in a concrete mix.

• The water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The ideal water cement ratio varies depending on the type of concrete mix and its intended use.

• For example, a typical water ce...read more

IS code of steel refers to the Indian Standard code for steel materials and products.

• IS 2062:2011 - Steel for general structural purposes

• IS 1786:2008 - High strength deformed steel bars and wires for concrete reinforcement

• IS 8500:1991 - Structural steel - Microalloyed (medium and high strength qualities)
