BB Stark & Group Interview Questions, Process, and Tips

M25 ratio is the mix design ratio of concrete which represents the ratio of cement, sand, and aggregate.

• M25 ratio is commonly used in construction for making concrete structures.

• The ratio represents the proportion of cement, sand, and aggregate in the mix.

• For example, a common M25 mix ratio is 1:1:2, which means 1 part cement, 1 part sand, and 2 parts aggregate.

The quantity of steel required for a 1000sqft house depends on the design, structural requirements, and type of construction.

• Quantity of steel will vary based on the type of construction (reinforced concrete, steel frame, etc.)

• Steel quantity is determined by the structural design and load-bearing requirements

• For a reinforced concrete structure, typically 1-2% of the total volume is used for steel reinforcement

The length of 1 TMT bar varies depending on the diameter and manufacturer.

• The length of a standard 8mm TMT bar is typically around 12 meters.

• Different manufacturers may offer TMT bars in varying lengths, such as 6 meters or 18 meters.

• The length of a TMT bar can also be customized based on project requirements.

M25 concrete ratio is 1:1:2 (1 part cement, 1 part sand, 2 parts aggregate).

• M25 concrete ratio is commonly used in construction for medium strength concrete.

• It consists of 1 part cement, 1 part sand, and 2 parts aggregate.

• The ratio is expressed as 1:1:2, meaning 1 part cement, 1 part sand, and 2 parts aggregate.
