Mölnlycke Health Care Interview Questions and Answers

Cube filling rod is technically known as 'Tamping rod'.

• Also known as tamping rod

• Used to compact concrete in cube molds

• Helps in removing air voids and ensuring uniform density

• Typically made of steel or iron

• Standard length is 16 inches with a diameter of 5/8 inch

Slump in concrete refers to the measure of consistency of freshly mixed concrete.

• Slump is determined by the amount of water in the concrete mix.

• It is measured by filling a cone-shaped mold with concrete, then lifting the mold to see how much the concrete slumps.

• Different types of slumps (true slump, shear slump, collapse slump) indicate different levels of workability and strength of the concrete mix.

• Slump test is commonly used in construction to ensure the quality of concret...read more

Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.

• 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 water cement ratio of 0.5 is commonly used for normal strength concrete.

• Excessive water in the mix ca...read more

M20 grade concrete is a mix of 1 part cement, 1.5 parts sand, and 3 parts aggregate, with a compressive strength of 20 MPa.

• M20 grade concrete is commonly used in residential construction.

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

• The compressive strength of M20 grade concrete is 20 MPa.

• It is suitable for foundations, beams, columns, and slabs.

BBS stands for Bar Bending Schedule.

• BBS is a document that provides details of reinforcement cutting length, type, and size of bars used in construction.

• It helps in estimating the quantity of steel required for construction.

• BBS is essential for ensuring the structural integrity and strength of the building.

• Example: BBS includes information on the number of bars, their diameter, spacing, and placement in beams, columns, slabs, etc.

Steel cutting length is the length of steel bars required for construction purposes.

• Steel cutting length is calculated based on the dimensions of the structure and the required reinforcement.

• It is important to consider the bending and overlapping requirements when determining the cutting length.

• Steel cutting length can be calculated using formulas or software programs.

• For example, for a beam with a length of 5 meters and a bending requirement of 90 degrees, the steel cutting ...read more
