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...
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...
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.

Cement grade refers to the strength and quality of cement used in construction.
Cement grade is determined by the compressive strength of cement mortar cubes after 28 days of curing.
The most commonly used cement grades are 33, 43, and 53, indicating their respective compressive strengths in megapascals (MPa).
Higher cement grades are used for structures that require higher strength, such as bridges and high-rise building...
Yes, the standard size of a concrete cube is 15 cm × 15 cm × 15 cm.
The standard size of a concrete cube is used for testing the compressive strength of concrete.
The cubes are casted and cured for 28 days before testing.
The cubes are tested using a compression testing machine.
The compressive strength of concrete is calculated by dividing the maximum load applied to the cube by the cross-sectional area of the cube.

Curing is the process of maintaining moisture and temperature conditions for freshly placed concrete to promote its hydration and strength gain.
Curing is essential for the strength and durability of concrete.
It involves keeping the concrete moist and at a proper temperature for a specific period of time.
Curing can be done using various methods such as water curing, membrane curing, and steam curing.
The duration of curi...
The strength of cement depends on its grade and type.
The strength of cement is measured in terms of compressive strength.
The grade of cement determines its strength. Higher the grade, higher the strength.
Type of cement also affects its strength. For example, Portland cement has higher strength than lime cement.
The strength of cement is also influenced by factors such as curing time, temperature, and humidity.
