Lea Associates South Asia Assistant Engineer Interview Questions, Process, and Tips

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
