BBS stands for Bar Bending Schedule. One way slab is supported on two opposite sides only, while two way slab is supported on all four sides.

• BBS is a detailed list of reinforcement bars in a structure

• One way slab is supported on two opposite sides only

• Two way slab is supported on all four sides

Unit weight of 12mm diameter bar is calculated using the formula: Unit weight = (d^2/162) kg/m, where d is the diameter of the bar in mm.

• Calculate the cross-sectional area of the bar using the formula: Area = π*(d^2)/4

• Convert the diameter from mm to m by dividing by 1000

• Calculate the unit weight using the formula: Unit weight = (Area * length) * density

• For example, for a 12mm diameter bar with a length of 1m and densit...read more

Slump test is a method to measure the workability of concrete by determining the consistency and stiffness of the mix.

• Involves filling a cone-shaped mold with concrete, then lifting the mold to see how much the concrete slumps or settles

• Helps determine if the concrete mix is suitable for the construction project

• Results can indicate if more water or additives are needed to adjust the mix

• Commonly used in construction ind

Cube test is a method used to determine the compressive strength of concrete by testing cubes of concrete in a laboratory.

• Cube test involves casting cubes of concrete and curing them for a specified period of time.

• The cubes are then tested in a compression testing machine to determine the maximum load they can withstand before failure.

• The compressive strength of the concrete is calculated based on the maximum load appl...read more

Density of steel is approximately 7850 kg/m^3.

• Density of steel is commonly expressed in kilograms per cubic meter (kg/m^3).

• The density of steel is approximately 7850 kg/m^3.

• Density can vary slightly depending on the type of steel and its composition.
