Plywood, steel, aluminum, and plastic are commonly used materials for shuttering.

• Plywood is the most commonly used material for shuttering due to its durability and affordability.

• Steel is used for heavy-duty construction projects as it can withstand high pressure and weight.

• Aluminum is lightweight and easy to handle, making it ideal for small-scale projects.

• Plastic is a cost-effective option for simple construction projects and is easy to clean and reuse.

• The choice of materia...read more

Diaphragm walls are used to create a barrier while retaining walls are used to hold back soil.

• Diaphragm walls are underground walls that are used to create a barrier to prevent water from entering a construction site.

• Retaining walls are used to hold back soil and prevent it from sliding or eroding.

• Diaphragm walls are typically made of reinforced concrete and are used in deep excavations.

• Retaining walls can be made of various materials such as concrete, stone, brick, or wood.

To calculate the quantity of concrete for trapezoidal footing, we need to use the formula for volume of a trapezoidal prism.

• Measure the length, width, and height of the trapezoidal footing

• Calculate the area of the trapezoidal base using the formula (a+b)/2 * h

• Calculate the volume of the trapezoidal prism using the formula area of base * height

• Multiply the volume by the number of trapezoidal footings needed

• Add an additional 5-10% to account for waste and spillage

Unit weight of circular bar can be calculated using a specific formula.

• The formula to find the unit weight of a circular bar is: Unit weight = (π * D^2 * L * ρ) / 4

• Where D is the diameter of the circular bar, L is the length of the bar, and ρ is the density of the material.

• Make sure to use consistent units for diameter, length, and density in the formula.

• For example, if the diameter of the circular bar is 10 mm, the length is 1 m, and the density of the material is 7850 kg/m^...read more
