Scc Infrastructure Civil Quality Engineer Interview Questions and Answers

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)

Bar bending schedule is a document that provides details of reinforcement steel bars used in construction projects.

• It includes details such as bar mark, bar size, quantity, shape, and bending dimensions.

• Helps in estimating the quantity of steel required for construction.

• Ensures proper placement and bending of reinforcement bars as per design specifications.

• Used by contractors, engineers, and construction workers for re...read more

28 days concrete strength is the standard measure of concrete's compressive strength after 28 days of curing.

• 28 days concrete strength is the standard measure of concrete's compressive strength after 28 days of curing

• It is important for assessing the quality of concrete and its ability to support structural loads

• The strength of concrete typically continues to increase beyond 28 days, but 28 days is the standard testing

Mivan is a modern construction technique using aluminum formwork, while conventional construction involves traditional methods like brick and mortar.

• Mivan is faster and more efficient than conventional construction methods.

• Mivan requires skilled labor for installation of aluminum formwork.

• Conventional construction is more labor-intensive and time-consuming.

• Mivan provides better quality finishes compared to conventional...read more

Self leveling concrete is a type of concrete that has a high flow consistency and is used to create smooth and level surfaces.

• Self leveling concrete is designed to flow easily and settle into place without the need for troweling or leveling.

• It is commonly used to level uneven floors before installing flooring materials such as tile or carpet.

• Self leveling concrete can be applied in thicknesses ranging from a featheredg...read more

The 1st Aluform mockup concreting typically takes 1-2 days to complete.

• 1-2 days is the usual timeframe for 1st Aluform mockup concreting

• Factors such as weather conditions, size of the mockup, and availability of resources can affect the duration

• Proper planning and coordination can help expedite the process

Process of variation involves documenting and analyzing changes in project scope, cost, or schedule.

• Variations are changes to the original scope, cost, or schedule of a project

• Variations must be documented and approved by the relevant parties

• The impact of variations on project budget and timeline must be analyzed

• Examples of variations include design changes, unforeseen site conditions, and client requests

The basic concept for construction of a substation involves site selection, design, equipment installation, and commissioning.

• Site selection involves identifying a suitable location for the substation based on factors such as proximity to power sources and load centers.

• Design involves creating a plan for the substation layout, including the placement of equipment such as transformers, switchgear, and control systems.

• Eq...read more
